What should I do to my new Z? On all of my other bikes I always removed my airbox lid, replaced the filter(UNI), unplugged the exhaust and changed the jetting. Do the same things apply to the Z? Also , I'm considering getting a ProCircuit T-4 exhaust and wondered if the head pipe is also needed. I have heard that some bikes dont gain much with the head pipe and some really benefit from it. Is there a big difference in power using the head pipe, or can I get away with the cheaper slip on only?

 

Hey Bubba, nice ride! [img]i/expressions/face-icon-small-happy.gif[/img] Search on this forum, there is alot on the whole air filter/ pipe thing on here.

Here's a list of what I've done (besides adding armor) all prices don't include tax or shipping & handling and are in US funds

(Free) cut out pea-shooter from stock exhaust pipe
(Free) remove snorkle cap and cut holes in top of airbox
($5) 140 Main Jet (has not been trail tested, may need 145 or 150)
($0.20) two No.4 washers to raise needle height (has not been trail test, may need to use only 1 washer or 3, it definitely needs a washer)
($5.00) speaker fabric to act like an "outwear"
($22) Uni filter
($208) 22Hx12Wx10wheel Realtors on Douglas Red Labels 0.190
($14) 13 tooth front sprocket (have not received yet)
($0.78) 7/8 inch clip to hold on new sprocket
Total ~$255

The re-jet, exhaust hack, Uni filter and air-box hack (Total:~$32) have definitely helped the Z's low end. It seems to stall at a much much lower RPM. It hits the rev limiter a bit faster now (according to my butt-dyno)

You can spend $70 for the alba K&N and outwears + $60 for a dyno jet kit or you can do what I did for 1/4 of the price. [img]i/expressions/face-icon-small-happy.gif[/img]
