Hey I have an 05 trx300ex and I was wondering which big bore kit would be best. Theres powroll, pease and a mods3 stage 3 330 package which comes with about everything. Powroll has a 350 kit but that involves stroking out the crank and sending in the parts for modification. can you guys help with this. which one would be the best.
