GPZ750 racer - Ti retainers?

hi guys

the GPZ racer project goes on....

have just finished removing a ton of crap from the GPZ frame (the side stand bracket alone was half a ton or so..), bracing tubes ready to be welded. Should be able to put the frame on the workbench and start adding parts rather than removing stuff soon.

engine cases are ready for assembly too so starting to think about some engine mods.

Had good experinece in my previous racer with Ti valve springs retainers, so looking for some for my 750/810.

Does anybody know about a source?
Or could kz 900-1000 Ti retainers work on 750 valves/springs too?

Cheers and Thanks

You beat me to it,

great dragbike stuff but not for long life.
stick with stock retainers but use a.p.e springs.
after all, he is the best source for valve springs out there.
nothing against him or his parts. that is just one part i have seen fail on a regular daily driven motor.
you need a lot of upper end oiling to keep them fresh.
a stock oiling system just can't provide enough.
but everything else from him for a as close to bullitproof motor as you can get but stick with stock for a daily driver.

Did you miss this part?

the GPZ racer project goes on.

It's a race bike, not a daily driver, Vintage racing.

Thanks guys, good to know that 1000 retainers will fit.

Will also 1000 springs will work on the 750?

cheers

Yes, I just posted the interchange from kawasaki.com parts diagrams showing all the bikes that used the 650 springs, and that included 750 and 1000. It was just posted yesterday I think.

Found it.

So only the J motor 1000 springs interchange apparently.

Contact Jay at APE and he can tell you exactly what fits.

thanks

good to know
