Hello I have a 2006 Honda Trx 250 Ex quad. The only mods I have done to it are installing a Uni air filter and a full Yoshimura Rs-3 spark arrested exhaust system. But after installing the exhaust I noticed it started to pop or backfire after letting off the throttle. Does anyone out there now what jet I need to run in my carb?? I think its running to lean.. Do I just need to change my main jet?? If so what size does it need to be changed to?? Keep in mind the stock main jet is a 95.. What about changing any other jets is that necessary??
Thankyou
Ricky
