Good thread I would also like to hear how many miles most peeps have on there tnytros and apex's w/o any internal engine issues (especially on stock rods and pistons). My cylinder guy (machine shop) bet me just the other day that my tnytro won't stay together for the whole season w/o breaking a rod or some other internal trouble. He thinks that 250 plus horse is just to much for the stock motor. He is not really up on this particular motor but has alot of experience with r1 motors racing street bikes. I took the bet and hope to be kicking back drinking my two cases of beer this spring and polishing my tnytro. When replying please post boost levels and if you have rods and pistons.
