What size bolt holds the sprocket to the Cam. I am putting one back together amd CANT find it

[@DesertBuilds760]

The thread pitch I am not sure of. The size of the head on the bolt maybe be 14mm or 17mm

A previous owner of my moto 4 welded the shifter to the shaft so I'm screwed

[@runit5772]

I had the same thing happen. I had to cut it off & split the cases to replace it😬
Still making a clicking noise in 1st gear!🤔😖 Shifts up thru the others fine but even on the downshift it hates 1st...

you take the bolt out of the timing chain than like it up

So your title says checking the timing and you just said you don't know how to do it. 😂

[@DesertBuilds760]

I said I didn’t know how to adjust the timing, I was just showing you how to check the timing to verify it is correct. 😅
