I agree with 22 racer on the idle gap. for some reason go-tec's seem more sensitive to that then other engines I have owned. I would have to say that would be because we use the lsn to tune it in. as far as sealing up the go-tec engines I did not until this past Sunday when I took my 5-port apart. now I will seal every engine I own,especially the go-tec's. when I can't get a 2.00 seal here in the states it's time to take extra measures to not ruin my engines.

By the way Rex have you tried the nitride parts yet?[crank shaft] Just wondering what you thought of them? advantage or gimmick? we are having a similar discussion on the shock towers, carbon fiber or aluminum on are jamminx-2s.
