I installed a tri spark electronic ignition and a dual 12v coil from cnw. Ran the test mode on the tri spark and excellent spark on both plugs.
Tried to start the bike and it is backfiring through the carburetor. I suspect the timing must be way off. Installation done as per instructions received with the tri spark. In other words, I aligned the only mark I could see in the window with the mark for 28 BTDC on the degree indicator by rotating the rear wheel forward.. Since these systems fire every 360 degree I did not bother to which cylinder was on its firing circle.
I believe the mark I was looking on was a mark on the rotor ? Is there any other mark I should look at ?
