About Me
My bikes are a Honda CR125 1994 and a Suzuki RM125 1977 AirHammer !!! Love old school Motocross!!! Been bringing back to life again the Suzuki RM125 after it was almost total trash,, No seat, no plastic, locked up engine from water rust,, dented tank..... After lots of work,, Now it runs!!! It had a 1976 motor on the RM and I just located cases for that are 1977 RM125. Switched out transmission ,clutch, new bearings and seals and a 1977 crankshaft, new top end first over bore ,just doing suspension work and than will add some paint soon! Love the bike!!

In my manual it says to line up the mark on the stator in the center of the .screw for a quick reference if you don't have the Suzuki tool dial gauge. The '76 RM125A engine has a 8 degrees BTDC if you have a dial indicator or use the method with mark on the stator. My '77 has the...

My basket looks good! When I have the basket in my hand , the bearing does feel loose. The tangs look decent , not all notched out. Hope the new bearing fits tighter.

Thanks WRH ! any idea though could the bearing have come from a street bike or would it have been a dirt bike of that era??? I think I will go the way of getting a larger bearing and getting the case machined.

Hello, I believe I have a problem with the crank seal on the clutch side. My friend and I replaced split the case, rebuilt crank and when we put in the clutch side crank seal, we believe it could have been little bit damaged in the process.
