I have 2000 Yamaha blaster 200cc. When I ride it the throttle is really not their. Sometime when its warm up a little sometimes it starts to rips but, It doesn’t really rip in any gear. I check the compression And I had low compression, so I put a new top end on it and I still have the same problem. I really don’t know what it can be. It was running good before the tors is still on but the wires for its removed any help.
