I have an 05 TRX 450r - I replaced the exhaust with a FULL exhaust system from AC racing - was told to run the main jet at 162, the pilot is a 42 needle in 4th clip.
It ran great at El Mirage 2800 ft. It did seem to sputter at the top - I'm assuming this is the rev limiter... I do have a non-programable PRO-COM cdi (don't notice a big difference)
First of all ...does this seem like a rich enough jet?? Should I go richer? Can I do anything else about the rev limiter - anything that would run better??
If i run my quad at pismo beach (sea level) How much should I go up in the Main Jet size??
I am also running a K&N with the lid off. Everything else on the bike is stock
