Hi team, My ultra 150 keeps blowing the same #3 cylinder every 30 hrs or so, it has a new oil pump installed and checked to spec, full gasket set with leak down test for crankshaft passed, full carbs rebuild. I have had the cylinder done professionally with full nikasil coating every time. From reading all of the forums out there it appears as though I have checked everything off I can. any ideas most welcome. cheers

Re: Ultra 150 keeps blowing #3 piston
I have been reading a bit on the forums and I have done the following, removed the air cleaner to see if all slides are opening fully, they are but all at different rates, the #3 cylinder is by far the slowest. what causes it to be behind and could this be the reason it is causing it to run lean?Cheers
