oil build up in silencers


Recommended Posts

I was at 25/320s with T5s, pro flow w/o lid, UNI filter, +4 timing, 150psi,145'asl.

 

With the lid on, I was at 25/280.

 

Different riders will ride in different parts of the rpm range and require different jetting.

 

In my experience, FMF have generally liked a one size smaller main jet when compared to T5s.

well guys it looks like the 280 is perfect for me I went to 260 and she was boggy out of the hole so I went to 300 and the plugs were just wet seems to like the 280 best

What was your testing process that led you to believe that 280 was perfect?
