Who is the best person to speak to about vfr750 tuning?

Hi there...

Im new to the forum and was looking for VFR400 frame info and 750 engine info... So I was wondering... Is there anyone specific on here I can chat to about tuning a VFR750 engine, or even where the best place to start is on engine development (94 - 97). Really I mean... Are there any known places where the 750's lack development or proper engineering. Are there any charicteristics that need working on? And does anyone know what company's still do bolt on parts for engine performance, etc?

Any info would be brilliant.
Cheers. C.

If you want to fit a 750 motor in the NC frame, then great, it has been done before with good results.
However, there is not much 750 info on this 400 site, try the VFR Owners club forum.
Brian Capper in Plymouth will tune your motor, but time and expense are not an issue with him, he only understands perfection.

Yeah, I figured as much, I was mainly on here for frame info, but I'm not entirely sure what I'm asking yet. I didnt really think I'd have much joy on the motor.... As for the engine work itself... All the development work will be done by our lil team. So im mainly looking for people to very roughly point me in the direction of stuff that needs looking at. So maybe someone has gotten a good result from modding the cams, for example... Or maybe they didnt. So knowing that gives me somewhere to start looking at... If you get my meaning.

Tony Scott used to be the man when it came to RC30 engines, I dont know if that applies to 'normal' VFR750's too.

Cool beans... I'll have a poke.

Some friends have been up to Tony Scotts today, and one is building an early VFR750 race engine and looking at chassis mods too.

If you really are genuinely looking to tune an engine, then I can put you in touch with him.

Well... Its a uni project on a motorcycle engineering degree, so it's actually all I'll be doing for the next 3 years. So if you could, that would be fantastic. So your mate knows its a proper project, the endgame is a bike using a carbon frame, 2D datalogging, carbon body and parts (brackets, rearsets, etc), full engine modeling in NX5 (and solidworks), Wave model and validation, microsquirt F.I. conversion, engine development and lightening with full FEA and whatever else we find. So its not just a "I might do this... Maybe, if I can be bothered"... It's actually a real thing. lol

Do you need any specific contact details?

That is just the sort of thing Richard is in to.
I also have a friend who built his own F.I. RFV 750 replica from scratch, using an RC30 engine and swinging arm, but made most of the rest of it, including frame, converted USD forks, new yokes, carbon airbox etc, modified NC35 boywork, his own EFI and injectors/linkage, did all the drawings, machining and building.

Email me at arsey30athotmail.com [at = @]
I will put you in contact with them.

Dave.

A friend was at Tony's on Sunday and he no longer prepares engines due to the compensation culture.
He is worried about being sued if a motor blows and causes an accident.

I know he has been worried for some time about the 600s running at very high revs using standard components [as the regulations stipulate]
