I want to change back to the stock Yamaha exhaust from a full White Bros. system that is on my warrior. The noise is too loud with the White Bros. (I don't want to deal w/the cops anymore). Can I just put the old pipe and exhaust back on, or do I need to re-jet the bike? The motor is currenlty jetted and bored 4 over.
Thanks

 

wanna sell me that pipe for like, 20 bucks?

 

oh, and to take that exhaust off, u just take the nuts out, into different peices. i think theres 2. take the header out from the front left fender. then just put the old pipe on the same way u took the performance one off.

 

$20? Come on. I understand how to take off and replace the exhaust, gaskets, pipe, etc. My main question is, do I have to make any internal mods with the motor previously jetted and bored out? My concern is, the stock muffler is for the STOCK motor and not one bored out and jetted.

 

well, u might have to rejet....but thats it. the fact that its bored wont affect the exhaust fitting or anything....$40?

 

If it had to be rejetted for the WB, you'll have to jet back down for the stocker. When you're taking off that header be DAMN careful that you don't put much torque on the header studs, if they are a little stiff spray some penetrating lube on them and let it sit for at least a few hours. They break very easily because of all the heat cycles they go through, and are a lot of trouble to replace.
