So for now mechanically, I removed the sprocket and release the chain, screws on the cover were seized and try with punch screwdriver and I almost #$%*ed the philips socket, but after putting release all and using a good manual screwdriver I was good.
I've also put the front end in place cause, finally my machinist Can't do me the job, so I send my drawings to other machinists, but I've no chance at all, no quote, not nothing...
Next will be removed the motor,
What are you using for clean it and repaint it ?
