Commando just won’t start

[motoalchemist]

My 850 mk3 broke down, sounded very rough before it stopped I haven’t been unable to get it to restart. The bike is fitted with Boyer ignition, I have good compression on both cylinders, fuel is getting through and there is a good spark to both plugs but it will not start. I have reset the timing several times using the marks on the flywheel but it still refuses to start. Tried to put a little fuel in the carb and a plug holes also a squirt of brake cleaner when cranking and still nothing not even a pop or back fire. I have also set tdc through the plug holes also and turned the piston back 10 mm but nothing just won’t start.

My 750 did the same thing, but it would run, just terrible, like it was running out of gas. it ended up being a broken wire inside the insulation right where the solder joint is on the pic-up plate coils...literally right at the coil. you could not "see" the break, but the wire was moving unnaturally while bike tried to run...replaced it with new pickup plate. eventually I went to Tri-spark. which I now have on all three bikes
