Mella yella (zxr400) rebuild.

[Kwaka-Kid]

ohhh man OUCH! shit me if i do my engine i couldnt afford to get it back again!
i remember my CB250RS piston was like $50 inc rings!

[FROSTY:Me]

yea -painfull hu -sheesh

[FROSTY:Me]

wel finally I have some action. The new valves have their seats cut, Pistons and rings are in and going up n down.8 valves of 16 are fitted the other 8 are waiting for the valve guide seals to arrive from japan.-for some reason kawasaki only kept 8 in stock at any one time. Mind you at $16.00 each I guess I can understand why.

50psi . I had 140 when i did the test. By the way if you had all the parts . How long did it take to do all the work??

[gav]

So, finished yet?

[FROSTY:Me]

still waiting for the valve guide seals to turn up. No point in puttin the thing together then takin it appart again

[FROSTY:Me]

now i'm in a total panic. -some clumsy clod-um er -moi -broke a compression ring on the zxr -big panic--and praying I can get a new ring set in time
the heads all back together butall off again

[Kwaka-Kid]

bugger dude! howd u manage that >? forceing on too much?

[badlieutenant]

I still need to sort out the rear shock but It might be a case of borrow the olins out of my zxr750

I might know a guy who can rebuild/fix ur shock. PM if your interested and ill get the contact number, I would name him here but I like been able to take my shock to him and dont want every1 too but he does an awesome job. My original shock has been rebuilt by him and its better than it was new. Even put a valve in so that I could re-gas if i wanted. Alot of people here probably already know who im talking about. I dont know what people charge for a rebuild but mine was 215.00 and soooo worth it. bike fells so much more stable and goes round corners like its on rails.

[FROSTY:Me]

bad-if ive got the time the shock wont be a problem--um ohlins.

[F5 Dave]

Maybe I should have popped in earlier, but apparently the go &/or if you have further problems is to use FZR valves in the ZXR, else replace the ZXR ones regularlyish.

The shock should fit straight in but the spring might be too stiff for the 400 as the 750 is like 40kgs heavier. It might be fine tho... you'd really want to test it first before rolling up to race day tho!

Ohh and its not that quick to do either....took me a whole evening to swap my rear shock!!!

[Kwaka-Kid]

yeh tell me about it, just spent since 7:30am installing a new Half system + muffler for my racebike... had to take the shock out and front radiators off (well, swinging) and what a friggin mission! again...

And whats stupid is i dont have time to do the same to my street bike as its got the best shock - and my racebike despite having halfway been there has to stay with the shit shock (6 preload settings, no remote res, and its pogo like damping).

So close... And more bad news? i just realised the system i got was a bloody standerd half system with a hacksawed off muffler and aftermarket/homemade muffler put on... ohh damnit!.. worse again? my last system was from the later model NC35 standerd system which gives better midrange!!!

SO WHAT THE HELL AM I DOING?!
man this is so damn infuriating.

Trial and Error is my way of life.
