No 3 is a problem cylinder on my bike as well as many of the other guys on here. Problems can be but are not limited to:
- Bike being parked on the side stand and water/debris sitting in the drain holes for that cylinder and then causing arcing from the spark plug to the cylinder head. Solutions include blasting out the drain holes with compressed air or if unavailable a bit of wire. Also if you have the original caps change for NGK and snip off 5mm of the HT lead.
- Spark is weak on that plug - swap some plugs around and see if problem persists.
- The bike has a wasted spark system whereby 1 and 3 spark together, even when 1 cylinder is on the exhaust stroke. You can thereby switch the caps from 1 and 3 and see if the problem persists. This eliminates a possible electrical/wiring problem
There ends the easy solutions. If none of those work you are down to carb balancing, check the timing, possible piston wear. Or like me you can just accept that the bike runs alright as it is and not look too much further into it.
