Jetting my 2007 TRX 450R

[Costa Mesa TRX]

I just put on a Trinity Racing slip on exhaust and received a jet kit with the pipe. It came with a 172,175,&178 main jet and a larger pilot jet. Anyone had any experience with the trinity exhaust systems and jet kits?

put the larger pilot in for sure,if its hot were you are I would put the 172 in if it cooler I would put i n the 175 and go from there.hope this helps I have a 165 in mine with FMF slip on Q4 and this is perfect.(this is with the lid off of course.):D
