I was riding wot and the spark plug along with the threads came out.

As far as I know, the cylinder studs only come in two sizes, a 6mm and a 8mm. BUT with the 8mm you may have either a 8x1.25 (most common) OR a 8x1.0 thread.i have tried this on my ht and it works like a charm! i tried it only because my old head got warped and wonders if it would work so i got a 48cc head with the bigger stud size( srry i forgot the stud sizes lol) and bolted it right on and i gains some speed outs of it, i never measured compression before and after but if you look at the combustion chamber size you can tell its a big difference, and by doing this with the current mods that i have(dellorto she 14.14 carb,trimmed piston skirt) i was getting 53kmh but after the head swap i got 56kmh
on some of the BGF rico 66cc motors one end of the stud is 8x1.0 the other ende is 8x1.25As far as I know, the cylinder studs only come in two sizes, a 6mm and a 8mm. BUT with the 8mm you may have either a 8x1.25 (most common) OR a 8x1.0 thread.
