jetting??

[john.E.business]

I just installed a yoshimura trc comp system and a k&n air filter and with the pipe it said run stock jetting... i took it out for about a 15 min rip and when it was idling the header would start glowing orange... now it is colder up here in canada but does this mean i should jet it? when i was riding though it cooled down and felt good didnt sputter or anything? should i jet it? i do have a dyno jet kit? and if i ride it without jetting it will it hurt my machine? thnx for any info....:confused:

it will burn a hole right throught the exhaust valves use the jet kit works awsome

Yeah if you get a pipe you most all the time have to rejet for preformance. Otherwise you wont get half the preformance you can get.

I run a sparks full system with the airbox lid off and a 190main with 50 pilot
