Ahh, that is for the mc19, the Mc22 addendum is in the back of that manual, it is a single pickup in the mc22 up and should be 470-530 ohms from memory. Something else to add is that the engine hunts quite a lot , ie is runs when he idle is set to 2000 - 2500 rpm and happy sits there for a bit then it might jump up for a bit to say 2800rpm then settle and drop to 1400rpm then stalk. I am going back to it this morning , I will retest everything and try and find what is breaking down I appreciate everyone’s input so far, this one sure has me stumped
I have tested the coils when they are hot and cold , I am testing the impedance from cap to cap and have wriggled the leads and it stays at around 25 ohms
Chris, because you swapped the carbs and plugs, I don't think it will be fuel related. Most likely electrical. Either a faulty component, or just a loose wire. Are you absolutely sure the harness you put in is a good one? I have a harness with one wire broken, so the left ignition coil doesn't get enough power to work properly. I found the wire in question, it was broken, but partially touching so it let some current through. If you have another set of harness / coils, give it a go. At least you can take that part out of the list of possible issues.
Will do Omar , I have the mc22 that I bought on the weekend, I have lots of Spares. What is frustrating me is that the cause is not easily identifiable , I know these bikes really well and I am confident in troubleshooting ability , this gremlin is down right evil.
for those playing at home, I swapped the coils off my race bike, same symptoms. Swapped the harness with a spare and found that someone had swapped the stator connector from female to male, so that one has gone into the scrap wiring bucket, I located my last spare harness and installed it, same symptoms. Swapped the TCI, same symptoms, swapped the reg with a unknown one and measured the voltages, it was 17v across the battery, stopped the bike, threw that one out, grabbed another, got 14.2v at 4000rpm tested the stator again and it should be .01 - 0.05 of an ohm per phase, these were almost at 1 ohm, decided to swap out the stator, I had to drain the oil and it came out milky so I guess it is time to do the head gasket. 2 steps forward, 23 back. Doh..……. sometimes I just cant win.
Indeed, a spare motor has gone in, she is now purring like a kitten. I will get a head gasket off xcitebikes and rebuild it, at least now I now what the vapour was, what is surprising is that when I changed the oil last time, there was no milkshake.
So, the headgasket was the only error why she did not start? Shouldn't the engine run with a "leaking" headgasket? There is/was compression in the cilinders?
Not yet, I am run off my feet this week , plus bumblebee needs to be reassembled Hard to find the mix between work and play with so many toys
