coffman's jetting?

[subdude]

well,I finally got a ride w/my new coffman's lightning pipe,as I was dissappointed to say the least.It was bogging and stuttering like the was no tomorrow.I was under the impression that I didn't have to re-jet.Am I wrong?Is jetting necessary?If so,what should I go with?It is a stock twin-carb superjet('97) with a solas 14/18.5 impeller(no other mods).Thanx in advance!

I would give coffmans a call. They were very helpful with my sizzler pipe and got the jetting dead on.

what do you mean no other mods, don't you have a a/c handle pole, and one highly cracked up ski????

sorry lenz just had to do it.

you almost always have to rejet when adding a pipe.

call them, Gary and Pam Coffman ( I think) they are really nice, and will fax you the pipe install instructions.

you need to verify your water routing to.

I sent an e-mail(2) to coffman's earlier this week,but,still no reply.Jetting is kind of touchy,so I don't want to mess it up.
Oh,by the way,slopokegtp,didn't you just blow up yer YZF?Not an issue with exceeding the carrying capacity,I hope!
