Alright so i'm looking at making the bike a little quicker here soon. I want to go with stage 2 hot cams exhaust and intake. I haven't quite made my mind up on which piston to go with yet. Is there a certain brand that is better for 4 strokes or better specifically for kawi? Also, I do want to go high comp to run race gas. Has anybody heard anything on the Vertex 14.5:1 high comp piston? I know a few guys with the 13.5:1 in their 12 and 13 kawi 450s that said it didn't make a huge difference. I'm 235 pounds and always seeking more powaaaa. Stock exhaust as of now going to do a full system soon. Also have a loudmouth intake installed on bike.
