pro-x piston rebuild

[LT250Racer609]

on the top of a Pro-X piston where is says IN....does that stand for facing towards intake or facing IN towards the exhaust...the reason why im asking is because i have never installed pro-x i have always ran weisco and they have an arrow which i understand....someone tell me pretty quick

thanks

its not my quad im rebuilding....its my friends im doin for him

what year piston

[LT250Racer609]

88

is there a large hole on one side? if there is thats the intake side

also IN is the intake side on that style, I just checked a old piston of mine which was 88 style.


listen make sure you warm the motor up real good when you start it and take it easy for 2 full tanks of gas. then you can rip it

tell me about your inline radiator cooler.... how does it work? where did you get it? does it work? how much was it?

Thanks

[LT250Racer609]

25$...motojoe sells it or i believe nacs racing does...it cools the anti freeze 30% more or somethin like that...works pretty good

[ESR350r]

can you find that on motojoe or nacs and send me the link? also is it just something splice into your line or is it powered by something?

I can't imagine it cools by all that much. It's just a finned piece of aluminum you stick inline with the hose, right? Have you ever done any actual tempurature comparisons with and without?

[LT250Racer609]

tests show it cools that much....its about 6 inches long and its wider then the actual tubbing of the radiator lining....with fins that are spaced evenly apart...just by lookin at it you can tell it makes a difference...its common since....more surface space which equals faster and better cooling...
