🤔Hello guys so I have an 03 banshee 350 that recently had carbs sync by a pro mechanic. However, after I got the bike back the bike kinda ran alil slow than usual and feels like only running off one piston. So I assumed I needed a rebuild but I wanted to take things in consideration i just replaced the spark plugs after I got it back so cant be that also when I put my hand over the silencers both feel hot and are blowing, but I have notice that the left side has oil leaking i haven't tried doing a comp test can anyone help me out do I need a rebuild or can this be a minor fix???🤔🤔🤔🤔
