I got a white bros e series exhaust and head pipe because my old exhaust was stock and looked rusty and bad, anyways, i got the axhaust on, but i couldnt get he headpipe on because the bolt on the back of the headpipe is rusted ( the one near were the exhaust pipe is, the 2 up front can be done with patience) so i am looking for help and advice on how to get it off, i was thinkin about cutting it thro the middle, taking off the front and then yanking the rear part of it off, but that leaves me with a half broken screw, so i dont think that will work. if any of you have any ideas plz tell me, i wanna get my new clean pipe on there. and one more question, when i am going top speed it seems to sputter at me, is that because it just wont go faster, or is it a breathing problem, because i kinda would imagine it would just be revving high without the gasps for air. thanks ahead of time.

 

that happens to me too at top speed.

 

spray some wd40 on it

 

you're probably hitting the rev limiter. that happens alot easier with a pipe. you may want to try some larger mainjets with that pipe to see if it runs better. as for the clamp, cut the old one off and get a new one.
