Sir, maybe your valve tappet is not properly adjusted...LOOSE and over TIGHT/ TUKOD Valve Tappet has the same result. IRRITATING TICKING SOUND

That Sound is your limiter stock CDI has a limiter for safety porposes .....
Change your stock CDI to RCDI ...
But if you change to RCDI you need to change your Stock CAMS and Stock Valve Spring to RCAMS and RACING VALVE SPRING ...

Good day to all i would like to ask about my mc i just put an kawahara black cam i am worried in my engine
When the engine is cold especially in the morning the tik tik sound of the cam is too low and sometimes i didnt hear the tik tik sound
But if the engine is hot the tik tik sound is too strong and so fast
Hoping in your kindness replies

Unfortunately, the UMA is not lighter than this(see below), a modified stock sprocket. But the UMA is a much needed piece for those running a jack-up(stroker) crank with a longer cam chain. The timing ends up being too far off, hence the adjustable cam sprocket.:D
sir, how u remove the housing? i try to drill the tag welding from the back, but failed, is too hard.
