I have modified the tail pipe, taken off the smog, re-jetted...
I am thinking about a FMF Q for better performance and sound -
I hate the sewing machine effect that I have now.
What is a good tail pipe?
Can someone help me???
My CRF450X sounds likes its having major valve problems.
I had (1) adjustment then went riding, within 2 hours its making some rattling sounds that just arent right-especially after spending $7200.00
