If it was fuel related, and I'm guessing you're thinking it wasn't mixing well with the oil and not getting enough lubrication, wouldn't the pistons also be nasty?
I got a 4mil cub unported, M&M crank w/ TZ bearing, M&M pump gas and alky domes, 1-5 duneable override, billet basket, real strong runner.
You lookin to trade straight up?
The 2 FAST bikes (I believe both are DMs) are always there and area always some of the fastest bikes. Bo_didlys DM and 4mm cub was holding it's own as well as M&Ms bikes and Shearers. I saw one or two pretty quick Packard cubs and one sexy bald guy on a pink frilly banshee
