400ex build

[jkosakowski]

Im starting to plan for the winter build. I race harescrambles so i want more power all the way around im thinking of going with a 11: 1 comp piston and a stage 2 cam and a new cam chain just wondering if you guys think this will help get more power in low mid and high.

should put you in good shape just make sure to check the bore and make sure its within spec . and do new valve seals while ur in there LD

.020 over 11:1 piston (only if you have to bore it out) an 05 450r carb 1 tooth bigger on the rear sprocket

I race harescrambles and did an 11:1 je piston, sparks x1 cam ported and polished the head and 450r carb. Really woke it up and makes it a good contender...
