I have a CB125 t2, (twin cylinder, 1980)
The issue is the kick-start. When I bought the bike the sellers bought it out running. I handed over £880 and stuck it a van to bring home, and that's when the fun started. At home it would not start, no matter what I tried, so I had a good look at it, and discovered numerous faults, among them timing was out by two teeth, there were no rubbers connecting the carbs to the air box, (they no longer make them, and they are a special shape) and it burnt oil. The rubbers I fashioned out of 40mm car hose and I redid the timing, fitted new points etc, and eventually got it running, enough to take mod 1+2 on it. Once that was out the way it meant I could use my 250 again so the 125 had a big strip down. I ended up needing: new barrels as one badly scored, hence the burning oil, new valves, guides, seals, pistons + rings. Eventually I had it sorted, but one niggle remains. The damn thing is a pig to start, though once going it ticks over nicely, and I think it's linked to the kickstart lever. From what I can assertain the lever is the correct one, but it hits the footpeg on the downstroke, so it's like only getting half a revolution out of the engine. If you remove the foot rest the lever travels further down, so engine turns over more. Due to the lever shape it only fits on the splines in one place, so the lever can fold back out of the way, in a recess next to the clutch cover, so, my question is after all the rambling, what is wrong? PS, the pegs are original, and just bolt to the engine and have a dowel that fits in a hole so will only fit in one place
