He may just need a freshened up top end. Sure bad gaskets to cause the problem. If the rings were stuck in the grooves, i'm thinking you need to rebuild the top end.
The only problem with VDR is Dale and all these guys are not track riders, for them to buy a membership on top of gate fee is kinda painful for a guy who might go there 2 times in a year.
I had an amazing time, I need to get my stamina back... SOON! Trevor is frickin fast on the DS, I was eating him up on the straights but he would throw up a wall of dust and I couldn't see. I'm not about to push it through the dust just in practice.
