Bill easy to spot, the B100P is actually 118cc but as you can see from the cases it runs a longish stroke and a huge flywheel
the other side
the stator plate. Same 3 screw mounting pattern as all TM/TS250
the flywheel, TS250-1 B100 same animal..
a flywheel and crappy stator I was going to flog the primary coil from but someone had beaten me to it..
get this, I spent about 8 hours today and last night trying to get spark. I changed the primary coil to the known good one, I changed the ignition coil 4 times, the plug cap, the plug twice, brand new points, double checked all wiring and connections for earthing or leakage, I rewired from the coil to the ignition, I tested the condensers and resistance and such and it fell within specs, made sure the coil had good earth, kill switch was disconnected ,tested coils and plugs on other bikes and they all worked fine, checked the ignition was not 12 volt ala TS400's, flywheel woodruff key was there, cross referenced the coils and numbers to B100 but nope, they're the same, nothing worked, still I had no spark. Guess what 'I'd' done wrong?
