No leaks on the fuel tank.. checked it under water and blew unto the pressure line.. I also loosened the mounting screws because of the 1st gen v-one rrr tank issues with the upper plate.

Basically it is very inconsistent to tune.. I had lost the factory defaults for the needles and very well out of the ballpark for the settings. So I started flush on the medium speed and low speed needles and started to tune the high speed needle. But when I get I thought that I got a good tune on the HSN (good response and good smoke) after a while it suddenly richens itself. Maybe because it was loading fuel at idle due to very rich LSN? hmmmm.. Will try again to tune..

Thanks!
