Pretty sure I fried my IC ignitor?

Here it goes:

Had the bike running fine, carbs sync, colortuned. Just got done checking valve clearances, 1 and 4 intakes were a hair off spec, obtained the numbers off the valve shims and put back, rechecked clearances, stayed the same. otherwise everything else is fine. Compression test 125 across the board.
So here is what the ignitor is doing. Carbs have been cleaned, boots in good condition, should be no sign of air leakage.
Good spark to 1-4, ok. no spark to 2&3. ok makes sense. Check all my connections all seem to be fine, however, I noticed that when I grounded the metal plate on the back of the ignitor it kicked in spark to 2-3. So i'm thinking that I fried a circuit internally and now its arcing the spark relay from 1-4 to 2-3 at the same time causing 1-4 timing throughout the timing causing high rpms.
I believe this to have happened due to a negligent move of accidently causing and arc from the solenoid-battery terminal to frame while running.
Anyone else ran into this problem? or make sense?

 

i had a similar issue with my bike after i got it all reassembled, where i had only 2 cyclinders fireing, and really high rmps and eventually the other 2 would fire over. it was due to carb float levels being off, after some adjustments to the float levels bike ran like a dream and all four cyclinders atarted evenly.

I see your in Sioux Falls, if you need any help shoot me a PM and we'll try to get together and clunck heads over the issue.

 

Did you damage your TCI? Maybe.

Will that cause high RPMs? No.

Are the valves in spec or aren't they? From what I read they're not.

"should be no sign of air leakage." doesn't mean that you don't have a vacuum leak just because there shouldn't be one.

It also sounds like the carbs weren't fully serviced; float levels wet-set, etc.

Even if it were firing all 4 plugs every time it fired, it wouldn't make the motor rev high. And it's HIGHLY DOUBTFUL it's doing that.

I think you have two different sets of problems going on; fixing the ignition won't fix the carbs. And you may not actually have an ignition problem.

Get out your service manual and diagnose; don't guess.

 

an accidental arc from solenoid to frame shouldn't go after the tci anyway.......

Yes, all but two valves were in spec, which will be soon replaced and back in spec, the two that were not were on intake side 1-4, just under the .11 clearance.

Yeah, I'll definitely go back through the carburetors, again; was the plan.

Its not that I'm guessing, I'm merely thinking out loud before referencing to the the service manual. We all know that service manual is always the infallible answer for troubleshooting, I don't know what the problem is with theorizing without actually acting on it.

appreciate the feedback.
