Wk125rr

[bennell]

Hi all!

Ive recently acquired a WK125RR as a cheap run around and project. To cut a very long story short, im wondering if any of you informative bunch know how to do valve adjustments i.e. have a "guide" and also know the clearence sizes? As they are really loud despite the throaty exhaust. I believe the engine is a a zongshen SB125(zs156mi) watercooled but there is zero info on the net about them.

Ive attached pictures of the engine if anyine could help
The first picture showing the left of the engine, basically mine looks identical except those two covers arent chrome nor oval, they are black and round.

The other part ive outlined is mewondering if thats the cam chain tensioner? If so, how do i adjust.

Thanks in advance
