Prima Pipe owners

[goatlover]

I had a shop install the prima pipe and the jet. Runs nice. powerband is smooth all the way through to 50.

got a couple of questions:

underneath where the pipe connects to the motor there is a lot of oil residue, is it normal? It looks like its leaking from from the exhaust gasket...

also my top speed is 50 maybe 55 is this normal?
anyone know if we can change the reeds to carbon fiber reeds for better flow?

Thanks.
