I see what you mean tho. It has been spluttering pretty badly and popping on decelleration..
Also the plug read as mega lean
Is it worth spending the £40 on a new valve or should i look for a used one?
What could cause all of this to happen? just wear and tear? |
Desmo cams accelerate and decelerate the valve without help from a spring, so all the forces are transmitted to the cam drive, and if the nut is not doen up properly, it will allow a tiny bit of movement, which, when you ride, er, enthusiastically, as you have to on a 600, causes a tiny hammering effect, which can only get worse.
A good mechanic will notice this movement when they change the belts, but if corners have been cut, the movement will get worse faster.
