All 32- 1986 Vfr 750R Rebuild I'm so mad at myself for having taken so long to discover this thread. What a fantastic build and a gorgeous bike! If you're in DFW and still happen to have the bike, I'd love to see it one of these days!
- 96 vfr750 cbr929 pistons???/ gotta give this topic a bump just cause its too cool not to... and eddy, your idea of machining the tops of the 929 pistons (if theyre too tall from the wristpin centerline to the top of the piston deck, that is) is…
- Texas VFR Meet 2011 Oct 28 & 29 sounds interesting. im looking forward to seeing when the date is set for this one.
- 96 vfr750 cbr929 pistons???/ flyguyeddy Hmmm. Do u think 1mm would be too much rise? at this point, a proof of concept using the silly putty idea i posted here earlier might actually be necessary....
- 96 vfr750 cbr929 pistons???/ JZH I should have my 837's original pistons in the garage. Which measurements are needed? The RC24 was originally designed to be 750cc (or 748 or whatever); the VFR700F was designed afterwards (RC26), so it would be…
- 96 vfr750 cbr929 pistons???/ ok to start with, YoshiHNS, you did pose 2 good questions. the 837cc kit is an overbore only. this basically replaces the stock 70mm pistons with 74mm pistons. and yes, the VFR engine cases can in fact take the giant…
- 96 vfr750 cbr929 pistons???/ Dutchy Please do the test run with you standing behind a thick Lexan shield...... well one trick ive seen engine builders use is to check the valve clearances to the piston using playdough or silly putty. basically, put…
- 96 vfr750 cbr929 pistons???/ ok i answered my own question on this one....the 900RR piston is only 71mm and the 954RR piston is 75mm, so the 929RR piston is the only one that will substitute for the straight out 840cc, +4mm overbore conversion for…
- 96 vfr750 cbr929 pistons???/ suddenly i'm curious..... are the CBR900RR and CBR954RR pistons still 74mm like the 929 pistons are? this comes down to the question of whether the displacement difference in the 900RR, 929RR, and 954RR engines were…
- 96 vfr750 cbr929 pistons???/ mcrwt644 'Mike Velasco' that name sounds very familiar from my days at a speed shop in San Diego...I'm wondering if he did my 99 F4 1mm over in 01..... Ok, so 929 pistons are very much less expensive. My question…
- 96 vfr750 cbr929 pistons???/ rangemaster Those listed big bore pistons go +4mm = over 880c-thats BIG. The kits I remember went 840 tops, did JE make TWO sets of big (and really big) bore pistons? I would think 880 0n a 4th gen 750 case would be…
- 96 vfr750 cbr929 pistons???/ i agree with the idea of using the 929 wristpins with the 929 pistons....that does make more sense than using the vfr wristpins. as for the rings, i think it would be best to buy new piston rings, as well as connecting…
- 96 vfr750 cbr929 pistons???/ ok 3 replies in order of posting.... Rosso.....are you saying that the valve measurements arent in the factory service manuals for the 3-4 and 5th gen vfr's? I was able to easily find these measurements in a chart in my…
- 96 vfr750 cbr929 pistons???/ does anybody have links for various VFR service manuals that can be downloaded in .pdf form? regarding this thread, I'm specifically looking for the manuals that would cover the gen 3-4 bikes, and the manual for the 5th…
- 96 vfr750 cbr929 pistons???/ I just found a page in the service manual for my bike that lists the specs and measurements of the valves in very similar detail to that of the charts that Rosso posted earlier in this thread on the pistons. If we can…
- 96 vfr750 cbr929 pistons???/ mcrwt644 That is exactly what I was thinking ^^ I've got a line on a gen 4 engine for about 150, and it runs, so that is where all 'experimentation' would take place wow, 150?! seriously?! dude thats WAY cheaper than id…
- 96 vfr750 cbr929 pistons???/ V4 Rosso mcrwt644 and you can do a valve job at home, leave stock cams in, You can also have the cams reground for some more lift or fit VFR800 valves (and seats) which I think are about 1mm larger in diameter. The…
- 96 vfr750 cbr929 pistons???/ hmmm seems ive really started summin here lol :biggrin: , i reckon it needs to be found out once and for all with a definitive answer. oh yes. this thread could potentially open up one hell of a can of worms. my…
- 96 vfr750 cbr929 pistons???/ just to put a little note on this thread...im about to absolutely lose my mind here, as I am looking at the same piston spec chart in the manual I have for the 86-87 VFR's, an already knowing beyond the shadow of a…
- 96 vfr750 cbr929 pistons???/ V4 Rosso I doubt you can go this far with an overbore. You decide, here are some numbers: y'know rosso, you say that, but this is the typical size of the pistons in any 840cc overbore kit. I'm gonna start doing some…
- What's the best R/R Go with either an OEM replacement, or Rick's. Whatever you do, AVOID Electrosport R/R's. I've heard nothing but terrible things about those.
- Building an RC30 ooooooooooo, bike porn! (and here i thought this was a clean, family oriented website!) ;) love the vid dude, thanks for posting it!
- Has Anyone Ever Seen Delkevic Headers I cant speak for any VFR as of yet, but I do have experience with a Delkevic header. After I acquired my 1998 Yamaha YZF600R, i decided to find a header to couple with the Yosh slip-on so I could complete the exhaust…
- crash sliders [image: View Post]coffeebrake, on 22 October 2010 - 07:00 AM, said: That's it, frame sliders. Are there any for the VFR700/750? as fate would have it, ive been looking into this exact question in the past week, and what…
- Pics of VFR700 (86) w/ F2/3 wheels please? smackdoogle, this is a conversion that ive been wanting REALLY bad for my 87....ive seen other pics of bikes with these wheels, and IMO, they look 100x better than the stock 3 spoke wheels that our bikes came with (not…
- More woes from a 23 year old bike So I'll get right to it...normally, my old 87 VFR is the perfect example of age-old Honda reliability. Lately though, it's been giving me plenty of grief. I can ride it around for about 15 minutes or so, be it around…
- 1986 Vfr700 Conversion To Electric yeah no doubt, frodus had mentioned something about fitting that e-vfr with some cobalt racing bodywork, and im itching to see how that bike will look when that work is done....
- The High Mileage Thread... What Do You Have On Your Vfr? so im curious....some folks on this thread have some REALLY high miles on their old viffers (107k + on a 1st gen! wheatie, you rock!) im curious as to how some of yall get so many miles on your bikes. i guess this would…
- Engine Swap 86-87 Vfr im surprised somebody even got an 87 motor to run on an 86 bike with the 86 wiring harness and CDI box....ive had both an 86 and an 87, and the CDI boxes were different. as for the camshaft position sensor, this part…
- The High Mileage Thread... What Do You Have On Your Vfr? 46000 miles on the clock so far, but i ride this bike more than i drive my truck (at least when she's running right and the weather isnt horrid). vfr's really are great commuter bikes, even the old 1st gens :fing02:
- Shoot Me Now Please ok for the record, the DN01 is *not* the same as the SD01 scooter.....its a totally different bike that thus far hasnt been imported to the US. now as for the DN01 being rumored as the next platform on which the VFR is…
- Quick R/r Question one major problem on the r/r's on the older vfr's is the fact that theyre internally grounded. this causes them to heat up significantly, which is one of the root causes of why r/r's burn out so often. I realized that…
