WANTED Race / Performance parts for 1st gen

[Jason 38]

Wanted,

race / performance parts for 86-89 VFR 750. Looking for, but not limited to:

Any HRC race kit parts (exhaust, radiator, rims, front end, wiring loom, cams etc)
Rear sets
Race rear subframe / bodywork

I am running an 88 VFR750 FJ in a race series here in Australia called New Era. Any setup tips, do's and don'ts, especially engine tuning (jetting, best plugs to run, timing/ignition set up, can run racing fuel? and so on) most welcome!

Rgds,
Jason Light

If you have a 88 J you have a 41mm forks and 17" wheels right?

The 86-87 HRC bits for engine as pipe and cams will not fit as you got diffrent parts.
I would suggest finding a more open pipe like a Laser slip on or Motad full exhaust, are still made. And a jet kit.
If you only ride track whit it, then remove the fan behind the radiator, saves a lot of weight.
As for wheels you can proberly fit a newer Honda wheel whit floated discbrakes as you have 296mm discs. For the rear a CBR 1000f wheel can be made to fit. Spocket needs to be moved inside, stock brake disc fits and is right distanse from center of wheel.

Good look!

Thanks,

Yep it is the 17" model, and I know they did have bigger valves for example over the 86-87 but I had been led to believe cams for one thing were compatible? Certianly a lot of parts were common so I would still think a lot if not all 86-87 bits would fit. Radiator fan is coming off, plus some other bits that will save weight, but how about fuel pump - can you set these up for gravity / vacuum feed only???

At least mine does already have CBR600 wheels however I would still be interested in lighter aftermarket or HRC rims from the racing period (late 80's)

Thanks for the advice, bit by bit I'll get this bike how I want it! It's half the fun, right??

I'd leave the fan on and hook up a manual switch for it. When you start making some real HP it will heat up more. Waiting on the grid, the cool down lap and cruising through the pits is where lots of bikes start puking water.

For the Fuek pump, I guess its a must.
For the cams, The 86-87 VFR had scruve adustable valves, and the 88-> VFRs has chim adjustable valves, so I think the cams aint the same.
The 2 bikes look werry alike but many parts are diffrent:
the 88-89 has diffrent electrical system, fork, wheels (thro rear fits betwen the models), subframe, lower front fearing, exhaust, front brakes, frame (front part), engines top and so on. One big ? for me is the shock length, as I know the rear linkage is identical whit a 87. The 86 and 87 also has soem diffrences, like rear shock + linkage and electrical (ignition mostly)

Also I just found in a dealers catalog micron exhaust a RACE exhaust listed for the 86-87 VFR750F and the 88-89 VFR750F !
