  1. Past hour
  2. From my past experience with other electronic devices (like remote controls), buttons like this are usually made in a sheet, so I would expect both of these buttons are part of the same sheet sandwiched between the plastic and the circuit board inside the instrument panel. If so, wouldn't it be possible to 3D print such a sheet using TPU filament? Not something I've ever done, but I have read about it! Ciao, JZH
  3. (Does everyone understand that "ergal" in Europe refers to 7071 aluminum? For that matter, the same question re "inox"!) Ciao, JZH
  4. That's a cool little plane BLS. And now I need to apologise to JZH for hijacking his thread.

  6. Thank you for the advice. I will get it checked during weekend and see how it goes. I always questioned it as it looks odd. I used to have a yamaha xj600N and i remember it was running a bit better and starting as well, holding idle revs much better, being a carburettors fuelled bike as well. Also, i forgot to mention, that ifi keep the throttle steady at let's say 4000 revs, it will fluctuate as well. Cannot remember if the engine sound was changing as well. Will check that and post a video.
  7. Very slow progress, unfortunately: huge workload and family issues take me away from my shop. Then, where were we? Carburetors assembly and protection panel. This panel is meant to isolate carburetors vane from the heat coming from the front cylinder, also calming air turbulences ahead the inlet snorkel. Well, I thought to use it to hold the horn, too 😁 It should be cool to say that I did to bring the masses close to the center of gravity, improving handling and blah blah blah 😎 In reality, I did to remove its bracket and connection bolt (simplify, then add lightness) and to get free room on the bottom yoke to use the workshop pivot stand without any constraint. Working in that zone, I did another small mod. This is the only addition I did on the bike, but the pros are enormously overpowering the added weight. I installed a vent port for brake bleeding into the threaded hole just below the front cylinder inlet manifold, used to connect a hose for carb sync. This procedure is very annoying, so I decided to keep a hose permanently connected and way more accessible. Then, carbs went in place and it was the time for the airbox to be refined. Since I removed PAIR and crankcase vent connections, the internal bracket for its reservoir are useless. If they're useless, there's no reason to keep'em aboard. Here's the airbox with its bracket and hose connection: and here's with no more 😆 then, airbox went in place and the new 3D printed trumpets as well. They come with 4 arms covering the 8 connecting bolts, preventing them from drifting all around in case of loosening. To prevent their own screws to get loose, I secured them with safety wire. NOTE: the 3D printing material is solvent-proof. In fact, I submerged the prototypes in gasoline for a whole night and they resisted perfectly. To close the airbox cover, I found a set of ergal Parker screws; why using heavy screws to connect light plastic items? 😎 Next time I'll take the occasion of the oil change to replace the flywheel with a lightened one:

  11. there's basically no room behind the right side rad, unfortunately.
  12. Yesterday
  13. 220F is not really that hot, if you had a dial gauge it would be about half way. The fan should be cycling on/off around that point (technically on around 208-216F according to the manual). 252F is redline hot, time to shut down and seek shade and cold brew. Because of the side mount radiators I doubt that they work all that well without the fairing being present to channel the air correctly. Different to a front-mounted radiator in that respect.
  14. This sounds sensible Mohawk. My 5th gen does not like low idle speeds and can get cranky and stall much below 1500rpm. I call it a feature, not a bug. My stock 5th gen revs up very freely from idle, much more so than my 6th gen which feels like it needs some fuelling mods (but won't be getting those).
  15. SO! Flushed coolant and swapped for a 50/50 propylene instead of the 30 year old ethylene. Might thin out with water for better heat transfer, and freezing is NOT an issue here. Took it out for a little without the side fairings, STILL hitting 220f+. How hot should a vfr be? Anyway I'll probably do the vtr fan swap, also has anyone put a fan on the right side radiator as well? Just trying to stay cool in this pit I call home. I suppose the heat just makes the breeze of the bay all the sweeter.
  16. So the rpm at idle is low so it will flutter. That pick up is slow when you revved it, probably because the rpm is low. My Rapid Bike shows the stock tacho on mine reads approx 300 rpm low compared to the digital readout from the Rapid Bike interface. Try increasing the indicated idle to 1500rpm & check the balance. I only use 2 gauges. One stays on reference cylinder & the other is connected to reference first & adjusted so they match perfectly. Then #2 gauges gets moved between the other 3 cylinders & then I swap 1/2 & confirm. Mine revs much faster than yours & is smooth all through the rev range when throttled up at idle.
  17. Very interesting and thanks for the thoughtful diagnosis. Do report back on the effect of your changes please.
  18. Ah, now there's bragging rights. You can't beat a bubble canopy, a lot of horsepower and free airspace!
  19. Not sure how I missed this, but I flew a P51 for an hour back in 2009. Still the best hour of my life 😁👍
  20. Not quite the Top Gun hangar that Terry posted a picture of, but you've piqued my interest. So what is the aircraft? Presumably prop powered? Homebuilt. Microlight category? Aerobatic capable? Looks splendid. I've always been rather envious of you chaps in the US with so much freeish airspace
  21. I managed to get a quick ride in on Sunday afternoon which was a mix of good and bad. The good was that the fork was considerably more supple and comfortable to ride on. The bad was that when using the brakes in anger downhill on a bumpy road, they dived really quickly and bottomed the fork out which started the tyre hopping with the ABS doing its thing, which was hardly ideal! I believe this was indicative of way too much compression damping bypass (where the oil bypasses the shim stack), but not related to spring rate, preload or oil height. There is a built-in bypass port (a small diameter drilling) in both the stock pistons and the Gold Valves, that allows fluid to pass from the high-pressure to low-pressure side during compression, and this provides much of the low speed compression damping, with the shim stacks controlling the high speed damping. Fork dive on brakes is a "low speed" movement, hitting bumps is "high speed", where the speed referred to is shaft speed. Some further diagnosis was required but I think I have solved that. It appears that the compression pistons have to be installed near the very end of the mounting shaft, otherwise they sit too close/slightly over the open ports in the cartridge wall, which allows fluid to bypass the valve. The Gold Valves are a different thickness to the stock valves, and so spacers are in any case needed to make up the total length so the retaining nut sits in the correct place on the threaded section. I suspect I had the Gold Valves sitting a little too low on the shafts due to incorrect spacer placement above the valve. I have shuffled the components so the sequence is now: cartridge base / spacers / shim stack / valve body / check valve / check valve spring / retaining nut. When I compare the revised configuration to the OEM compression valve, the o-ring my Gold Valve is now sitting 1mm further into the cartridge tube, which should ensure it seals properly now. Garage bounce tests feel a lot better, now hoping for some fine weather this weekend for a test ride. I have also decided to add a cruise control unit to the 1200, and have ordered the Veridian system from Canada, which was remarkably cheap (CAD$416 = USD$306, including freight and a 12% discount code I found in a Manwithabike Youtube clip). Sadly the local poilce are upping their speed monitoring and CC will be an aid to retaining my licence. I will post up any observations around the installation and use when I receive the gear. I have also bought some PAIR blanking plates and will install those at the same time, just to get rid of the extra plumbing. Lastly I have some footpeg lowering blocks from Jaws Motorcycles, intended for a CBR1100XX but visually they look like they are spot-on for the 1200 which will hopefully give my ageing knees a little more relaxation; my only resevation is that the brake pedal will need to drop further which may entail removing the locknut as that is already bottomed out.
  22. I doubt if 3D printing would lead to a successful replacement. It is just a bit too small I think. You could try. There is no need to 3D scan it. Anyone with some 3D modelling skills can remake this part when it's in his hands.
  23. one option might be to pop out the good one, have it 3D scanned, then 3D print new ones out of TPU, which is a soft flexible rubber.
  24. Hi Anonymous, Thank you for your donation of 25.00 USD. We look forward to improving the forums with your donation. Thanks VFRDiscussion

  25. I agree with Terry. That looks completely normal; my 8 gen is the same.
  26. Sorry, I have no idea where you could get a replacement button beyond buying a panel off eBay or similar and cannibalising parts. Others may have a more info. Perhaps look at threads on instrument panel repair on the 5th gen forum. Many have taken them apart to install led bulbs or repair circuit tracks. The photos might well show you what's possible. If your button pressed in, it might be retrievable.
  27. surely some clever lad could easily nock out copies with a proper 3D printer, eh ? maybe even carbnfibr ?

      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

      gallery_491_3463_419309.png

      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

      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 smile.gif

      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:
