Hey I need some help on finding which bore kit is the best for my 05 trx300ex. Theres a 350 kit from powroll which involves stroking out the crank and sending in the parts. Pease offers a 313 kit. theres a mod3 stage 3 330 kit which i belive you bolt it on. If you guys know any info on this let me know whats up. Which piston is better wiseco, JE, or the powroll.

yes FST is great to deal with, you can pick, the 330 kit is nice, it doesnt require case machining and comes with an 11:1 wiseco piston,,

its definatly a deal for 295.

remember your gonna need your cylinder bored to match the sleeve and the sleeve bored to match the piston.
