Could it be flooded , and daft question ,have you got the leads on the right plugs, though even not with the wasted spark one of them should have fired

 

the leads are from the left ignition coil * 1 and * 4 and from the right ignition coil * 2 and * 3

The contact wires on the left ignition coil yellow / blue on the blue plug and black / white on the black plug

The contact wires on the right ignition coil blue / yellow on the blue plug and black / white on the black plug

 

Yes right there matey, have you tried squirting the starter fluid into the cylinders without the carbs in place, sorry if I'm going over what you might have already done, but maybe take the carbs off again just to get a clear view of whats happening

 

No, I have not tried that yet.

And frankly when I had to put the carbs on it that was very difficult they almost did not go into the intake rubbers.

And I'm so tired I've been working on this bike since last September.

I think I'm going to sell him to someone who is technically savvy.

That would be a great shame matey, keep going , what do you have on now is it the Sticks or the Coils, but Im sure if you get any sort of firing out of the engine that will spur you on, I know the carbs coming off/going on is a pain , but you've got a great looking bike there , dont let someone else nick it from under you.

 

+1 That's a pretty sweet build. Shows a lot of care/attention went into it. Also, I totally get that feeling of just being done with a project. Happens to the best of us (a lot)

Even if you had to take it to a bike shop for a bit of professional attention, that'd be better than trying to sell it as a non-runner. I'd call up a local shop, explain the mods, trailer it over with the jet kit, and tell them to clean/rebuild the carbs with the new jets, and troubleshoot spark. It shouldn't take them more than half a day. Include the known-good coils to make it easier on them (and cheaper on you)

If you do it in the off-season you'll get a lot more love - if you wait til springtime when everyone's busy they won't want to spend any extra time/energy on it. Just my experience

As others suggested, you're probably dealing with a carb issue. The jets should help, and some tuning will probably be necessary to get it running right. Also a heat gun and some dish soap (or fancy grease meant for rubber) will make those boots go on/off easier

If you're getting weak spark then that could definitely be making it worse. If you're sick of looking at the carbs, you could probably check voltage at the spark unit 6-pin connector, as well as resistances at the spark unit 4-pin connector to rule out problems upstream of the coils. It should all be in the service manual

You got this

 

Hello there thanks for the nice respons

I have decided to give it another last chance.

I'm going to order the jetkit from Sigmajets and then pull the carb off, completely clean them and put the new jets in it and see if he starts with this.

I have checked the coils and the leads with my multimeter and I also have spark now on the spark plugs.

 

That's it matey ,stick with it , I'm sure you will have it running with the help of the guy's on here

 

 

OK, I was looking at this post. What is the history of the bike? Has anyone played around with the cam chain tensioner? Where did the CDI come from? Is it the correct one?

I'm a bit confused by your last post. Were you getting good spark before or not. Have you tried to start it after establishing good spark?

You mentioned the bang from exhaust. If the cam timing is off with the proper CDI and good spark, this may cause the bang and non-start. If it were me, I'd check the cam timing if you have spark and fuel.
