Hello,
I have a 2004 Yamaha SR 250. I have recently changed the oil and cleaned tappets and the engine sounds great and has a lot of power. When I start accelerating it is fine but when I accelerate fully the clutch slips and the bike sometimes misfires. Is this serious? Do the clutch plates need changing? Or is it just a matter of adjusting the clutch settings and if so, how do I do this? Any advice would be great as I am new to the bike.
Thanks,
Grant
