CLASS at Infineon 2007
In 2007 I attended one of Reg Pridmore's CLASS days at Infineon and it was a blast. A sunny mid-May track day in NorCal is damn hard to beat.

Hello all VfR 800 1999 5th gen For the past weeks I’ve delved into fixing all the small and complex issues from my vfr, but it seems that I’m completely stuck with some topic in particular. Chronological Order of Events: 1. Initial Symptom: - The engine began to exhibit hesitation and jerky movements while maintaining a steady throttle position. 2. Diagnostic Code: - A long blink indicating an error code 10 was observed, pointing to an issue with the barometric sensor. 3. Sensor Replacement: - After conducting tests, a barometric sensor from a 6th generation model was procured and installed. 4. Resolution of Error Code: - The replacement of the sensor eliminated the error code, and normal operation seemed to resume, prompting a continuation of repairs. 5. Throttle Valve Synchronization: - During the synchronization of the throttle valves/starter valves, a problem was encountered with cylinder number 2. Detailed Issues and Questions: 1. Cylinder 2 Synchronization Issue: - Cylinder number 2 could not be synchronized; adjusting the screw only decreased the vacuum, and completely unscrewing it did not increase the vacuum beyond 1.8 cmHg. - Question: Could the mechanism be broken, or is there another issue I'm overlooking? Is it possible for a vacuum leak to affect only one cylinder's adjustment, despite all four cylinders sharing the same intake from the airbox? The hose from cylinder #2 does not appear to be cracked. 2. Power Delivery Delay: - After reassembling and testing the bike, a delay in power delivery was experienced during rapid and forceful acceleration, nearly causing a loss of control. - Subsequent testing revealed an error code 8, indicating a potential issue with the TPS (throttle position sensor). - Question: Can a vacuum leak be related to the issues I'm experiencing, including the inability to adjust cylinder number 2 and problems with the TPS sensor? 3. TPS Grounding Concern: - Research on various forums suggested that the TPS could be grounded, although the contacts appeared to be correctly in place. - A resistance measurement between the negative pole of the battery and the engine block showed approximately 200 milliohms. - Question: Is this resistance value normal? I'm not an expert, but having resistance on the engine block itself seems unusual. Please let me know if you need further assistance or clarification on any of these points.

How are these working? I see reviews of people banging their shins into them whilst getting on their bikes. Any feed back? thanks.

Managed to get quite a lot done. Found a good oil cooler with very good pipes this has allowed me to fill the bike with oil and confirm oil pressure is good. Fitted the new radiator and finished wiring the new switchgear but in the process I think I fried the ECU by sending voltage through the clutch switch. I also modified some plug caps from aliexpress for a cbr600 to fitvthe vfr as you can see in the photos. Clutch slave cylinder is leaking badly so will replace with an aftermarket Oberon one

I have never heard of this hack before. I'll have to say, I am absolutely not surprised it didn't work.

Greetings from Finland I thought I'd put here a little of what has been done to my beloved motorcycle over the years, especially in terms of power increase. the first two pictures show the difference between the old configuration between the Delkevic and the original exhaust. other mods are the same. -PAIR valve mod, Flapper mod, and airbox mod -O2 sensors bypassed -Power Commander V -Air filter Pipecross -Iridium plugs -LeoVince Slip-on. Dynorun 2023 in the picture shows the changes made during the last year. Other mods are the same except the original headers catalysator cut off. -cylinder heads are lowered by 0.4mm -intake camshafts 8gen. -Air funnels all long. In a week there will be another attempt on the dyno. Changes to the old one. -intake and exhaust camshafts have been increased by 0.8mm more lift -adjustable camshaft sprockets -exhaust camshafts 6gen the camshafts are 4 degrees later -intake camshafts -8gen the camshafts are in their original position -V-tec system deactivated -airbox modded (own design) -Modded Delkevic 4-1 headers to 4-2-1 headers (1 Cyl-4 Cyl. pipes same Collector and equal length. 2cyl-3 Cyl. pipes same Collector and equal length. ) 2/3 cyl. pipes are 10cm longer than pipes 1/4 cyl. I don't own a tig welding machine, so the exhaust pipe seams are welded with a mig and stick machine and it looks like that 🙂 I haven't been able to do a test drive yet, because the arrival of summer is late and it's too cold outside to go for a ride. My english is bad so i have used google translator

FJ still, but not fork yet, but carb diagrams. The old where no good anymore, even the plastic dip paint treatment didn't help, only worked for a day. Costly parts, OEM list price ~150€ each!, aftermarket parts locally in shop ~100€ each, managed to score these from ebay for 320€ for 4, and they are OEM mikuni ones! Have to say was quite tricky to get the needle plate in place as there is a spring under it to hold needle down, other a straight forward jobb. Next to get motivated to pull one more fork apart as lube the shock linkage

Hey guys, I have a bunch of levers for Hondas that don't fit on any of my cuttent bikes. Some new. One lightly used. Some OEM. Some aftermarket. No reasonable offer refused. Include shipping if you want them shipped. I can bring them to the May rally if someone would like them. They're in Charlotte, NC in case you're nearby. I think that the OEM ones are ~$20 each new and the aftermarket ~$10 each.

So I normally run a VFR400 axle/brakes & custom cush drive to allow that, so I could run my RC45 BST Carbon wheel. That wheel has an issue at the moment, so had to fi d a replacement. When I did the conversion 12years ago, there were loads of RC45 rear wheels about. But today they are almost unobtainium. So I had to come up with a means to get the bike back on the road. So stock axle was acquired, but without all the other stock bits it would not work. So a cunning plan was hatched to modify it to allow me to keep all my other custom parts. And hey presto here it is 😁 520 X-Ring Heavy duty chain (rated to 120hp), custom cush drive. Now stock rear axle nut & stock rear wheel, with VFR400 rear brake system. Note how much daylight through the stock wheel with my setup. Sprocket is an Afam 45 tooth for a Ducati 916 on a JT Ducati 5 bobbin QD carrier👍

What is it about that screw on arrangement that looks so, well just elegant? What chain are you running there Mohawk and is that a steel or alloy sprocket? EDIT: Oops that's a standard nut arrangement. Too much of the vino rosso. My apologies

Another run to Cycle Gear and tried on a couple Shoei's... same size, dammit they fit better. Lesson.... the supermodel is not always the one you want to live with!

So spent most of today putting my rear end back together. Took wheel to local tyre shop to get tyre put on, they did if FoC 😁 👍 Then reassembled the axle & disc, needed different washers as spacers due to 800 & 400 axle having different cutout for disc mounts. But we got there. Fitted axle to the hub & tighten everything up to the correct torque & axle spins freely 👍 Then connected the rear caliper to the brake hose & hung it from the rear of the bike to bleed it, much simpler with the bleed nipple at the top. Remembered to put something between the pads to act as disc spacer. All bled up very easily, hardest part was keeping my mini reservoir topped up, 2 full pumps & its empty. Then bolted caliper in place & put wheel on the bike & torqued up the wheel nuts. Removed centre stand whilst bike warmed up & took it for a brake test up my dead end street. All good, rear brake works & wheel didn't fall off 😂 Get an MoT Monday/Tuesday & then some test rides 👍

I think, this is maple syrup, not fork oil!

Thanks for sharing the pages

With style like that, could it have been anything else? Ciao, JZH

I've never seen fork oil that dark in anything!

Opened up the orginal forks today, Should have had a overhaul a few years back, I would say many years back..... Oil just black as a night And fork seals far from fresh looking The fork caps are sure billet made, but finnish is lacking Sadly the bush sliders are past there best.... So something again to order..... 90's CB500 should have same parts so should not be to hard to find. A quick search do offer them as package whit seals that I already have thro

If plugs are connected and not worn out ... Carburettor cleaning and new O ring gaskets all over sounds sound right to me. At least that was the diagnosis for my bike with similar behaviour. In my case the acceleration behavior was felt like a hesitation in the middle rpm zone - or rather the middle caburation zone. Idle and full throttle was OK, but these are different work zones for the carburettors. Spot leaks (smell) or sometime waterfall like leaks from carbs are due to aging of the o-rings and chemical reaction to the modern (unleaded) fuel. So this rebuild will be needed sooner or later.

Got my modified Crossrunner (same as VFR) axle back. Shortened then threaded so I can use my custom cushdrive & VFR400 brake parts. Thus keeping my chain & sprockets the same. Should get rear end back together this weekend 😁 Ready for MoT next week & NW200 trip on the 8th 👍

Indeed, this would be my last resort, too many opportunities to F... things up. running on 3 cilinders smell of fuel? been there done that, forgetting to reconnect 1 sparkplug boot.... Pull the sparkplugs and inspect them. Fitting new ones doesnot cost the workd idle the engine and spray brake cleaner amongst the carbs (take side panels off). does the engine react to this? False air Check that each of the 4 vacuum porst (1 each on each ciliner is cappd. Either by a small bolt or the spout with a rubber cap+clip any crack in the boots between carb and engine Take the fuel pump out the circuit (and disconnect the plug), reroute the fule lines. Will run fine this way as long as the tank is > half full to be sure.

The Last Day Of Good Riding Weather
Juniper Pass
I took a day off from work and also from my bicycle training to take out the Veefalo one last time before the weather turns ugly, supposed to snow the rest of the week and possibly start sticking to the ground along the Colorado Front Range. I took a leisurely pace up hwy 105 toward Morrison and got reacquainted with the bike since its been over a month since I took any sort of twisties on it at all, hwy 105 is a scenic ride along the front range between Denver and Colorado Springs, its mostly easy fast sweepers and lite traffic so its a favorite road of mine when going north. Then I have to negotiate a bit of traffic near Highlands ranch and up hwy 470 into the mountains. I decided to take the Morrison Exit and try either Lookout Mountain or head up Golden Gate Canyon - this time it was Lookout Mountain, I was sort of making it up on the fly as I went along. Lookout Mountain is my old bicycling haunt from my days while I was working at Coors, its a killer ride and all uphill - I don't think I could do it today If I had to, not quite there yet! I saw a whole bunch of riders doing it though and wished I was in shape enough to be there doing it as well. 30 more lbs and I will be able to do it! On this day I would do it on the Veefalo instead.
I took a video from the gateway to the top at the Lookout Mountain State Park, getting past riders, the guy in the green jacket actually pretty much astounded me with how far he had gotten in the short time it took me to set up my camera, some 3 miles at least and up to the gateway from the turn off at hwy 6! Amazing I thought. I took the first two turns slow then got more comfortable as I went up further, till I was doing well, I made some gearing mistakes and took the tight 15mph marked hairpins in the wrong gear so I lugged it a bit on one or two. Still enjoyed it though and then got off at the top and hiked over a rock outcropping for an overview of the road for the pictures below.

From there I headed up interstate 70 to Idaho Springs for a beer at the Tommy-knockers brewery, I was the only customer in the joint - slow day for them so they treated me like a king! I got a nice tour of the place sort of impromptu, they made me a nice Pastrami sandwich on rye and with the brown ale it was fantastic. I must say the beer is much better there than in the bottles - its always good at the brewery. I am glad I stopped

I finished my lunch and since the road to Mount Evans is right there I headed up Squaw pass hoping to get in some nice pictures I wasn't expecting what I found, ICE IN ALL THE SHADY PARTS
Icy patches on Squaw Pass definitely taking it easy on that road
There were some section where the ice covered the whole road for 300 yards or so I had to roll through it with my legs out to help keep the bike from sliding and falling over, I took it real slow. A Ford pickup was right behind me so I pulled over to let him pass but the guy was going slower then even I was so I pressed on - in places where I could see I just cut over to the oncoming lane and out of the ice where the sun was shining on the road more, but some places there was not alternative so I just had to go slow, good thing it wasn't slick but rather they tossed some gravel over the worst parts so I had some traction!
I did stop for pictures in all the best spots

I Am Back !
Not that it matters and not that I expect anyone had noticed, but to those who sent me "where are you?" I would like to say I am back. Not only that I am officially returning to VFRD after nearly 2 months break but I have also ridden my Hawk last weekend and had FUN! Let me restate that; I had major fun riding! Something I have almost given up on.
Most of you have been riding your whole adult lives and riding is not only a hobby to you, it is part of you. But I started riding three years ago and even though I have encounter some setbacks, till this spring I loved riding with whole my heart. However, I have always considered riding as my hobby. As a hobby which suppose to make my life better, more fun and more rich. Life is too short to do something which we don't fully love.
My love of riding received a first major scar this spring: I lost a friend on the racetrack. He was a total stranger who offered me his help after I lowsided at CMP track last year. I still remember hearing his "Hi, my name is Todd, do you need help?" while I was duct-taping my roadrash from ripped jacket. He helped me straighten up the shifter and we kept in touch. The next time we saw each other was the day he died.
With 9 months delay, I can say that Todd's death shook me more than I have realized. It rooted fear in me which was fueled by seeing and hearing about others getting hurt over and over again. If I was to summarize this year - it would be one big accident report. I became sensitive to every broken bone, every roadrash, every lowside. And even though I did 10 track days this year, I became slower and slower and slower. Suddenly, I have acquired this 'grandma' riding style on the road, frozen with fear that behind every corner there is car standing in my lane, or major sand trap or deer staring at me ... I was crippled with fear not only for me about also for my fellow rider.
So, at the end of this year, I rode more and more by myself. I could not bear the feelings of responsibility for others on the road and my lines were crippled by my own fears. It all culminated this fall at WDGAH. In a freaky accident Love2rideh82crash was taken down by a truck crossing into our lane. I was done. I finished the weekend, locked the VFR into a garage and took a break.
Until the last weekend, I pretended that motorcycles do not exists. As a last instance after 2 months break from riding, I decided to go to CMP track to see if I can still have fun. I also felt like I should go for the memory of Todd. I went and I had fun! I had much more fun than I expected and the most fun on track I can remember. Suddenly the whole track connected into an uninterupted line of turns and I felt one with the bike riding around! I was giggling like a little girl in my helmet and keep on giggling ever since
Granted I was not the fastest one and through out the weekend, I have never exceeded about 60% of my riding abilities, but I had no "oh-shit" nor 'blond' moments. I could have maybe go faster, I could have brake later for the turns and I could have lean further, but I am no Rossi nor Stoner. I decided to ride for fun and I had amazing blast riding well within my comfort zone.
I was proud of myself when, after bandaging Ricks arm, I was able to distance myself and go back to riding without the year-long fear. I did feel bad for him but the feelings were not crippling my lines nor my mind. And when a total stranger came to me and said "Hi, my name is Todd", my heart stopped for a minute though but I suddenly knew that my life went a full circle. I probably will never win MotoGP :idea3: , but I am back! :wheel:

Oops. I do believe I know how to post YT videos or they wouldn't be on YT. However I may have screwed up copying the link to the playlist. Thanks for the helpful comment. -
I think that you might not know how to post videos. You're in your YT studio in these links. You need the link to the actual video. -
