I use batteries with a built-in booster: https://antigravitybatteries.com/products/starter-batteries/restart-oem/atx12-hd-rs/ I have yet to charge one, and the first one I bought sat on the bench for almost a year before I installed it. That was 6 years ago, and it's still going. I've never had to use the restart function, but it's nice to know it's there if I do.

Hi Alex, sounds like you did a thorough investigation! Some less obvious causes for not priming is disconnected / poor connection to the injectors (ask me how I know!), cam pulse generator and ignition pulse generator. But, the FI light is expected to be turned on when the ECU detects these error conditions...

Picking them up Saturday looking forward to it

I had eight CBR929RR injectors tested today on similar 'spray pattern' and similar 'total amount of fuel over time'. Only one set of four (all four from the same donor) came out consistent and well performing. The 'shop owner' that tested the injectors was very kind and let me see it 'live'. He was surprised to hear I would be inserting it into a VFR from 1998. All kinds of questions came up: you do realize this injectors are used at 3.45 bar (VFR800 5th gen is at 2.5 bar)? But, your cam timing is fixed, so will you make changes to the air box to get more air in? How will you know you aren't running way to rich/lean? I explained that I will run it with a RapidBike ECU in combination with a O2 sensor (aka MyTuning), so I will be able to detect to rich/lean and it should be able to self regulate (when enabling that feature). I also explained I would see a 'tuner' to allow having a good first map and just see how the MyTuning would work out. The shop owner added that he would advice me to borrow a tool used in the Netherlands for periodic checks on gasoline cars, which measures CO, CO2, HC and O2. And the pro's would monitor 'knock' during the tuning.

I should not be attributed with anything in this area, except that I do pay attention to and note the different ways to accomplish this, and continue to voice my opinion that linked brakes do not belong on a VFR. A goddamn master cylinder mounted to a fork leg is just the start of the Rube Goldberg insanity, with multiple extra possible failure points, maintenance headaches and extra (unsprung) weight. "But... when it works, it works really good." That's great. So does my brain, hand and foot. And they are already along for the ride.

That's a steal! Enjoy the restoration.

Hi orendanger, having some experience on the subject (after learning a lot from this forum and its members). Front: - Original fork/calipers: drill an hole in left and right caliper (at a specific location in cavity of middle piston) to allow moving all three piston with one hydraulic connection (which then requires you to change the front primary brake master cylinder; 6th gen worked out great. Biggest 'issue' with original fork you have to fixate the front secondary brake master (the 'weird' moving caliper bracket on the front left). I did my own take on replacing it with a custom bracket, see here. - VTR1000F fork lowers and some RVT1000R calipers (Captain 80s) - needs some work to get the front fender mounted - VTR1000 fork lowers and some CBR954/SP2 callipers (Terry) - needs some work to get the front fender mounted Rear: - Original caliper: drill a hole in the caliper (at a specific location in cavity of middle piston) to allow moving all three piston with one hydraulic connection (which then requires you to change the rear brake master cylinder; the one from a CBR600 F4 worked out great - CBR600F4 calipers with a CBR600 F4 rear master cylinder (Terry)

I took the bike to work yesterday! I only live about 10 miles away, but after 18 months without a bike, it's great to be back! I did a longer loop on the way home (15 miles - had to be home for the kids!), and then pulled in to get petrol. Got back on the bike....."click". Dead battery. Grrrr. A friendly chap gave me a push start and I got it home and stuck it on a charger. Spent about an hour starting to chase reg/rec/stator stuff and then realised my solar charger isn't working!! So the battery must have been pretty low anyway, and when I got back on the bike in the petrol station I had the ignition on , didn't realise the lights were on as I as messing with the trip clock so I think that killed it. Checked with a multimeter and getting over 14ish volts when the bike is running so it's definitely charging. Easy fix there - use the bike! Exhaust clamp fitted. The clutch is not particularly happy when it's cold. This might be lack of use? It might also be that the oil although fresh enough looking has been sat in ther for quite some time so I've ordered oil/filter and will change that over the weekend. Speaking of oil, there is a little milky stuff under the oil filler cap and on the threads, but with the bike sitting up so long, I'm sure it's just condensation. Once she's warmed up, the bike pulls well but I'm idling at about 3k. Starter valves haven't been synced so I'm going to get a local mechanic to do that, I don't have the tools. Exhaust leak may have contributed? I'll find out when I take it out tomorrow . In the first 5 minutes it doesn't like anything over 1/4 throttle. It's still bogging down a lot until warmed up. Again, maybe this is just lack of use as it seemed to clear a bit quicker on the way home. I've put a bit of redex in with a full tank so I'll see how that goes over the next week or so.

The COP conversion is discussed here, Denso coils (Suzuki or similar) and a section of the FI wire harness from an earlier CBR1000, and it connects right up. For the rear caliper, you can make a short section of hose/line to bridge them. As I recall, swapping in a F4i rear master cylinder worked best with this mod.

Thanks for the looking out. Never can be too cautious. Yes, I have a batt tender with lithium setting. My other bike has had a lithium batt in it for 3 yrs. I don't ride many cold days any more, but I have never had an issue with the bike not starting up. My bike are always on a tender if they are not rode. I even have 2 elec scooters that have lithium batteries in them and rode them on cold days. From the sounds of it, you must steer clear of lithium batteries. I understand there use to be a big issue with lithium heating up and starting fires. I don't see that much any more. With that being said what do you do with your phone or any other rechargeable devices that you buy now a days? Again, thanks for looking out. I really do appreciate it.

much appreciated!

My search says that is correct. Every VFR from 1998 to 2008. It was superceded from 53105-MN4-000.

Looking to order myself some OEM handlebar weights off partzilla for my 5th gen, wanted to double check I'm ordering the right part. I googled the part number and put it into partzilla, it looks like the correct item but partzilla's fitment checker is saying it's incorrect. Anyone have some input? Part number: 53105-MN4-010 Partzilla link: https://www.partzilla.com/product/honda/53105-MN4-010

Just don't use the wrong type charger and carry a booster pack for colder weather as lithium doesn't like the cold. You will also need a dedicated charger if charging off the bike/ Dont charge it in the house ot garage unless you have good fire insurance. Seen too many pride and joys up in smoke, and the garage. Lithium apparently cannot be recycled either by all accounts as it is poisonous when made into batteries and cant be put in the ground. Is there not a picture floating about with thousands of tonnes of redundant lithium batteries that no one can take or wants?

I would assume not in the USA due to the restrictions on handling Lithium here. I placed the order yesterday morning and the battery was shipped and going to be delivered today. Gotta love quick shipping.

Hello all! So I started a project on a whim when I managed to score a pair of 8th gen lowers for cheap on fleabay. Managed to swap over my forks and Andreani cartridges from my 6th gen lowers… BUT. In my eternal wisdom and short foresight, I assumed that since the 8th gen used 310mm discs, I could get away with using CBR1100XX discs (310mm with the same mounting configuration as the 6th gen wheel). However, I forgot that brake disc offsets were a thing and now I’m stuck with a wheel that can’t fit between the forks. The 8th gen offset is 8.5mm whereas the Blackbird has an offset of 17mm. Does anyone know of a brake disc that would fit or how viable would it be to machine the mounting surface on the wheel to shave off a couple mm to correctly align the brake disc? Hope you guys have a great week!

Really good looking bike aren't they 😍

Ok that'll be my first checks to do then 👍🏼 cheers bud

Well, I have rebuilt and maintained a linked 5th Gen 800 and I'm a buffoon, so if I can do it, it's cant be that difficult. If you just want de-linked brakes, thats a different story. Best of luck

Looks like a fun project! I'd do a compression test on the engine(s) first which will tell you whether they are worth any effort. Then take the cam covers off and check the cam lobes and rockers for excessive wear, which was this model's Achille's Heel. It's been a long time since I have owned one of these (hence the black and white image...).

Ok so one of these has had the frame powder coated and some of the plastics and tank resprayed it was a mates dad's project he started probably 20 years ago was gonna strip both down to parts decide what's good and make one decent bike 🤞🏼 anything I should do engine wise to make sure all is good one was his daily ride before he started so hopefully there's on good engine there 😂 any checks I should be doing before I get things apart or any advice would be most helpful only just completed a cx 500 build but didn't have to do anything to the engine apart from clean and polish it ! So if there anything I should be checking let me know IMG20260404113845.heic

I create more easily fixed problems. The issues with bleeding, and maintaining the linked brakes are way more complex then calculating the piston diameter and stroke

Looks good, but I've never heard of Ionic. They don't say where the batteries are made, so presumably in China! Ciao, JZH

I will add this video to help owners decide...
