Faulty gearbox CG125

Evening all!

Bought a Hongdou 125 (Honda CG125 clone) as a non runner to rebuild get back on the road after 22 years off it.  Gearbox has a problem in that you can only select 1st, Neutral or 2nd but if you turn the engine using the crankshaft bolt then you can go all the way through the gears, but on the next turn of crankshaft it can only select 1st,N,2nd again. Any ideas? I'm in an IVA so sadly I couldn't buy a brand new CBR125R like my niece so stuck with this for the moment!

Hongdou 125 year?

Hi Thenetman and welcome to the site:smile

Sorry don't completely understand what you mean???? but if your talking a none running engine(I think you are?) then I would think when the engine is running it will select all gears as the lay shaft will be turning to(driven by the clutch)and will mesh the gears.

Good Luck KCMC  :tongue:

Faulty Gearbox

Hey thanks, It is a non runner - it's my first time at stripping an engine so I didn't know that :)  Hopefully it'll be running by next week or it'll go bang next when I fire it up.
