high compression piston?

[300EXrider02]

how can this help? how much money about do they run at for a 2002 300ex? are they hard to install? worth it?

[honda250xrider]

they cost about 100$ at least mine did it was a weisco high compression piston 12:1 yes it helps and i think it was worth it if you are willing to spend the money for it

What type of fuel do u run with that 12:1

[Blake24]

A piston alone isn't gonna do alot.....you need a cam and such to compliment it

[honda250xrider]

yes it helps alot with cam bigger vavles bored ported and such alone it doesnt do much but when u have these all together u will find a huge gain and i run race fuel right now

with a 12:1 piston you have to run 110 octane

i'm about to go into my motor also, i wanted to know what to get and how much it would cost...i asked for his opinions' on everything...here's what he said....

You could put a high compression piston in it for $85, a cam for $150, valve springs at $105 and an oil cooler at $95. This won't outrun a 400EX - you would have to go to a 330 kit and ported head with a good pipe. Also, you will need to modify your black box for another $85 to get rid of your rev limiter. No matter which way you go with our products, they are very reliable especially when you put an oil cooler on it.
