I got an FMF Fatty Gold Series pipe and the FMF PowerCoerII silencer to go with it. I just installed it and when I start my 1999 Blaster, the exhaust sounds weird. It sounds like there's a bean in a can jumping around.

I am currently <u>uploading the video to YouTube</u> and I'll post it as soon as it is approved.
Any ideas in the mean time?

The only thing I didn't do, yet, is put the spring on.
I believe the sound is coming from the front, where the pipe connects to the motor.

 

Why didn't you put the spring on? Is it lost in the exhaust?

 

I just put the spring on and it still sounds just as bad and leaks exhaust.

Do I need sealent, or to rejet the carb?

If I need to rejet the carb, how do I do it?
THatnks.

 

STOP RUNNING IT. you need to rejet your carb whenever you put a new pipe on... if you dont you will run it too lean and you will screw up your engine

 

It sounds perfectly normal.

Before you ride it you will want to have the carb re-jetted as was mentioned already.

If you don't know how or can't do it yourself have the local shop jet it properly for you before going wide open throttle. Running it at idle won't hurt anything though. When you go WOT is when you increase the load and need to worry about running lean.

 

Thanks.
I also found this, for future reference to anyone who may need it in the future.
