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! Tim

Triumph ST 1050 Problem

My Triumph is reluctant to start, then does not run sweetly for first minute or two, then's fine.  New battery 2 months ago, kept on "smart" charger spins the engine well.  Several good doses of injector cleaner and new plugs have made no difference.  Any suggestions?

Anyone with opinion? Sorry language mistakes.Regards

Front wheel/brake.

Then today I was riding to work and starting getting a kind of rattle through the bars and what sounded like the front brake rubbing every few wheel turns. I changed the brake pads and the inboard pad was worn pretty much all the way down, and the brake calipers and discs were red hot (obviously indicating rubbing). The problem still persisted and I ...

I had no front brake light on my 2002 Fzs600fazer, I removed and cleaned the microswitch and tested it was working, then I touched together the two wires and the brakelight came on, unfortunately I forgot to switch off the ignition when I re-connected the wires to the switch, I now have no lights or horn and it's not the fuse that's blown, any ideas?
