Start with some feeler gauges (cheap) and proper values specific to your head/engine. Then determine what type of valve train do you have. Shims or the ''classic'' rockers? If shims, then take all the meassurements you need, and then order some shims, if required. If rockers, well time to get your tools out.
If you have no idea, have a experienced mate checking what you're doing.
Get the feeler gauges (thin metal plates), and start with taking measurements. Write it all down on a piece of paper, then refer to your workshop manual. Maybe you don't even need to adjust the valve clearances. ____________________ '87 Honda XBR 500, '96 Kawasaki ZX7R P1, '90 Honda CB-1, '88 Kawasaki GPz550, MZ 150 ETZ

Well, the least complicated answer would be just keep removing stuff until you can get where you need to be. ____________________ '87 Honda XBR 500, '96 Kawasaki ZX7R P1, '90 Honda CB-1, '88 Kawasaki GPz550, MZ 150 ETZ

Hi the WR125 uses the same engine as the R125 both of which have the head from the YP125 majesty scooter.
They use a single cam acting on dual rockers which use the traditional lock nut and adjusters to set clearances without any shims.
Dug this out of some old service notes for the YZF-R125, sorry i dont have them specifically for the WR but i would be very surprised if they are different.
As said above if your not 100% sure you can do this or your abit of an ape with tools... then leave it to somebody who knows what they are doing
The clearances for the R125 are
Intake 0.1mm - 0.14mm
Exhaust 0.2mm - 0.24mm
Both measured on a cold engine.
From memory you will need to remove the tank, side panels and the radiator. Then front and back of the head remove the 2 inspection covers exposing the valve adjusters.
Next remove the cam chain drive sprocket blank and cam position indicator blank on the left side of the engine.
Rotate the crank anti clockwise (direction the engine rotates) until a small single line (looks like a capital I) lines up with a punch mark on the crank case cover, that will be top dead center and both cam rockers should wiggle ever so slightly assuming the are not under load due to no or negative clearance.
Check your clearances. This is a bit of a pain in the arse tbh as the valves sit along way down in the head, i had a collection of 5 shims i had bent specifically for checking WR and R125 as i was doing them so often at one stage.
If they are ok awesome!... put it back together and go for a ride, if they need adjusting put an Allen key into the adjuster itself loosen the lock nut and move the adjuster out/in, lock it off and remeasure.
Thats as much as i can think of, only other tip is use good tools because if you round off the lock nuts on the clearance adjusters you are opening quite the can of worms.
