Jeff, I'm curious what the issue is with pump gas. I use ethanol free 92 pump gas and at my elevation (about 3300 ft) it seem to work fine. Is there a symptom I should look out for that will steer me towards race gas?

Are you still using the oem front sprocket? I read somewhere dropping 1 tooth in the front in addition to the black throttle tube is a great combo for the contact 250. I'm ordering the black throttle tube this week and might also get a new front sprocket.

Thanks!
