Is there any one out there that can help me ive just rebuilt my tr1 engine and all is well apart from i dont seem to have a spark on the rear cylinder ive checked the coil and all is ok ive also checked that i have reconnected everything in the right order but still nothing. Any one out there have any ideas?

so if you swap coils you get a spark at the rear but not the front?

if so than check your wiring to the coil and in particular if any wires got caught coming out of the stator when puting the left side cover on.

yep i get a spark if i swap the wires on the coil. looks like im going to have to take of the casing and check there as well. thanks for the reply dood. now having issues with the  starter motor not engaging..

the starter is as much to do with it not firing.....the starter is ok if the bike fires up straight away....i replaced my starter for a new four pole permenant magnetic type to stop the drag on the battery, works well, but still doesn't engage well at times...

also battery needs to be good.....coils are linked with some other devices (starter relay, tacho, tci) so check all connections, if the bike has sat for a while during an engine rebuild..pull all the connectors apart and put them back...these are 30 years old....loose connections are common....

the battery is brand new it was the first thing i replaced. on the wiring side the bike has been turned into a hardtail and has had all new wiring as there are no indicators or kill switches it's as basic as basic does. i checked with the previous owner and he said it was all working ok till the front piston seized. looks like i'm gona have to strip off the case and investigate further........bugger........
starter wise looks like a new one may be needed....
