I am just trying to fix my bike.After a lot of searching on the engine and carburators i found out that the problem is on the electrics!!!It is an mc 21 but with mc18 r2j electrics and i really need a schematic.The last few days when i drive the bike, the tachometer and the bike stop working for a few miliseconds.I don't know what it s going on and i have to check everything concerning the electrics.Also note that when this happens everything else is working except the engine and the tachometer.Maybe this is a ground wire somewhere in the loom!!!

P.S.:Someone sent me an email and i have erased it by mistake.Please send it back on ee4998@ee.teiath.gr.
