Rebuild of the skyjet SJ125 GY-6
Hi all, been a while, not long ago bought a skyjet 125. Dead cheap and on a 2008 plate. Here in the uk. using the cg125 156fmi pushrod engine.
The bike was well worn covered 12 thousand miles already. but was in dire need of repair. The engine was wobbling around in the mounts when changing gears, later on investigation the mounts had broke from the frame. I have stripped the bike down to the frame and rewelded. also one of the mounts has cracked the case at the rear, I small puddle of oil under the engine. now fixed. Whilst the engine was out, it was stripped down, split the case, and then tig`ed. so here is the bike, when I got it. Been buying new bits here and there, better bars and grips, 17t front sprocket, new chain, even new valves. as the old ones were pitted due to being badly adjusted. |

This is a great project! Thank you for documenting you work with photographs, and sharing it with us.
I have moved your thread to the Dual Sport Forum where it will deservedly receive greater exposure.

You're really transforming that bike. I like the socket head cap screws on the rear sprocket; are they stainless?

We love photos; thanks for posting them. Did you install new grips? If so, what brand?

Almost a whole bike again. What are you doing with the magneto cover?
As a point of interest, another fine member from the UK found an 18 tooth sprocket, but that might be a bit much for your application.

I think that's the same headlight I just bought. May we see how you mounted yours?
