I have a 2006 GT125, when riding and i get up to full revs its like riding a bucking bronco I have to reduce throttle by around half a turn to stop it. Does this sound like a timing issue? Or maybe a fuel issue? Its beginning to drive me mad, Can anyone help?

Is it consistent, inconsistent or just after starting? If you are seeing it just after starting, you may need to warm the bike before hitting the road. If it's happening inconsistently, it could be a fuel line or tank issue. If it's a consistent issue, you could have several issues including timing or rollers.

Just some thoughts....
