'jet' 80's info

[gubba]

does anyone have experience/knowledge with the "jet
80's"?
i've installed about 30 moters into customer's bikes but never a 'jet'.
the price is right but what is their reputation?
i don't want to put a piece of crap in a customer's bike....



thanks for any input

stay dry

Well in my case, color would be a HUGE difference! (I bit my lip while writing that), For X-mas. I did 2 builds using new Schwinn Riverside's(7speed). I ordered 2 PK80 Stealth slant head kits. and the usual front mounts (SBP) etc,, well after the usual NGK plugs/tuning etc. The black is a Lame dog, un-tune-able, @#^%$#@$^^. The Silver is a dream machine. I plan on getting with PK tomorrow about warr. No power to.

The quality was good as far as being clean and clutch adjusted, rings all on ring pin guides, nothing missing.

I took the Silver for a ride today, I was taking advantage of the cooperating weather of 20deg F. :-). I finally tweeked the carb enough for it to clean out upstairs. Good pull and Huge Q too.
If you need any measurements or anything, let me know. The only thing that is different about the kits is the paint color.

I have both the black and the silver PK and they have both run the same for me.

If your black one isn't running good there must be somethin goin on.

What exactlly is it doing. I can prolly help you get it fixed up and runnin good.
