Many thanks for your reply.I have a question about the coils on Triumph 500 (ET) but not sure where to post? Advise please.
I have fitted after market coils to my 1966 Tiger . Since fitting I've had no end of trouble in getting the bike to run properly!. Even broke a Kickstarter in the process.
With nice new/clean plugs the bike would start almost first time, followed by a brief minute of reasonable running and then it's as if the choke was switched on!. On inspection the plugs were sooty black!.
Not thinking, I assumed that it was running rich and must be something to do with carb/fuel delivery. After trying new jets, needle etc etc, the bike did not run any better!.
So here's the thing, when I test my new aftermarket coil with a multimeter it shows Secondary to be 11.4K!.
I cannot find what the correct rating for my bike should be and my old coils(original) don't give me any reading at all on my meter.
Logic is telling me that if the resistance is more in a coil, then the plug spark will be weaker on an et bike like mine.
If the plug is not burning all the fuel then it will behave like the choke is on??????,..........or am I barking up the wrong tree?.
Simply put, does my new coil have too much resistance causing the plug to have less spark and eventually sooting up?.
