top end kits

[trx400EXtreme]

i was wanting to get a new top end kit for my ex. i was lookin at wiseco's kits. they good? are there better ones? also with a stock motor should i go with the 11:1?

Wiseco isn't bad, i've'd used them before. The only problem i've had with them is the ring that was supposed to go in the top grove didn't fit. Most people prefer JE pistons. you can get top end kits from colby at c&d racing< site sponser. As for compression 11:1 would be fine.
