Hi Marcel thanks for getting back to me

Had a ride out today did 4 miles if that bike died would randomly fire but not run pushed it home it then decided to fire up again while running it still has the flat sound to it most it would do is 50-60mph also struggled to rev past 11k rpm’s did a compression test bike near the limit on the rear bank but the bike has been like that for a while (125psi when warm throttle open) yet it ran spot on when I first got it compression hasn’t changed i looked over the bike valves sealed fine piston rings where snug at 0.25mm on my feeler gauge put it back together and ever since I’ve had this running issue and a flat single cylinder sounding vtwin
