Are parts hard to find? Any trouble area to look at? Place to look for parts? Any info helps. It will be raced so it needs to look and ride good... thanks for the help vital
I pulled lots of holeshots in 1981 on the Kx,,,class was full of Rm125s and Yz125s
I dont know what kaw did to the motor in 81,,but it was not slow
The 80 and 81 looked the same,but they were not,,just make sure its a 1981
The Shop
Not one problem,,I think I did the top end 5 times that year
Maybe I got a good one,,but it was very reliable for me
No mods but top ends and tires
Not very many around here,,lots of 1980s,,but hardly any 1981s
My friend advanced the tmng and cut the back of the piston. I never rode it but he said it was fast and he had good results .
Keep fresh o rings for the exhaust manifold. They were the worst leakers. When they do they sound horrible SD power really drops
