bigtizzles Posted March 28, 2011 Author Report Posted March 28, 2011 So, 20cc or 21cc? Is there really that much difference? It gets pretty hot here, and 4300 ft elevation. I'm probably gonna buy this thing this week. Quote

I'm probably gonna buy this thing this week. IMO I would atleast run the 20's at that high of elevation. My 19's do great at 5000ft on pump gas. Quote
bigtizzles Posted March 28, 2011 Author Report Posted March 28, 2011 Ok, thanks for the info. What kind of jetting do you run at that altitude? Quote
bigtizzles Posted May 2, 2011 Author Report Posted May 2, 2011 Ok, so 20cc at 4000 feet will give me a 140 comp and I should be safe up to 160 on 90 octane? Quote
