No... Thrux is a 360 degree, our cruisers are 270 degree. Your best bet is to call or email them.
You could also consider the Procom unit as its new and programable. Read the thread about them first.

Makes sense.
So my bike has as far as I know only Bub pipes on it, NGK plugs, stock airbox, I don't think the carbs have been messed with and It's usually 60s-90s here in SD. So I'm assuming the procomm may be an alternative. I don't have much cold weather to speak at.
But there is alot of bad in the thread about procomm =( makes me worry.

Get the part number off yours and look for one that matches on Pinwall. Personally I would stay away from Procom until they get the bugs out. If I need one I will either shell out the bucks for a new stock unit or go with a used one from a place like Pinwall.Engeland Moto is another option, they went the extra mile for me, great folks to deal with and honest. Prices were good too. Click Me I was just looking at what they have right now and it doesn't look like any CDIs are available right now.

I pulled the tank and checked the wiring to the coils and to the plugs. Everything is nice and tight. I pulled the CDI (1291100) and checked the connections to it, they seem solid and the box looks fine, no damage, cracks, melting or anything. It doesn't rain much here so If the CDI is bad it may be from the heat of the engine/pipes.
I'll look for someone that is willing to swap CDIs as a test and also keep my eye open on ebay for a used one.
On the bright side, i've been cleaning up my bike while doing this and it looks almost new. Lol, wish I could ride it.

I'm just catching up in this thread. To test the CDI you can switch the wires left to right and right to left and see if it changes your firing from side to side. That is the easy way to test if it is a CDI issue.
Last spring I had a high rev issue like that and it was a vaccum issue. The cracked air box could be doing it. The rubber in the diaphragms could be going bad too if it has sat for a long time like that. Which would run well at idle and then when the slide moves it would show up. Finally the jets might be a little gunked up from varnished fuel. If we get to that point you could soak those in carb cleaner to clean them up.
For now try the CDI wire switching. Try to rule out the misfire from side to side first.

I just caught up on this. I'm thinking you should just stick to a thorough fuel system cleaning before you go any farther. Carbs, hidden filter and petcocks. Take your time an do one thing at a time, it's all easy enough especially if you use your cell phone or digital camera before you disassemble the parts so you can insure the reassembly is correct. Then just go ahead a replace all the vacuum caps. Try that easy stuff first, remember Occam's Razor.

So this morning I fired up the bike. At first it was kinda hard to start, even with the choke (I've hardly ever had to use the choke at all to start this bike in San Diego). It started up but died out quick.
So I shut off the choke and I adjusted the black knob below the left carb clockwise a bit to make it (richer?) and it increasd the idle a bit (1200 rpms) it stayed running. Kinda rough at first, and I could feel some heat from the right pipes like the right side was firing. Once it warmed up I had to turn the black knob CC to reduce the rpms back down to ~700-800.
I took it for a spin, rough acceleration thru 1-2 with low power, 3-4 seemed smoother with much more power, never made it to 5. The whole time I had alot of decel pop from the right side.
Came home, checked the pipes. Left one was nice and hot, the right was still just warm.
So it appears to me (correct me if I'm wrong) the bike wanted to and tried to fire on the right side early on, but later I was just running on the left cylinder.
What should idle RPMs be at (no choke) idealy?

So you've managed to isolate the problem to the right side. The popping sounds like a vacuum leak and the lack of firing sounds like a clogged carb pilot/idle circuit. Once you've established that the intake behind the air filter is clear, you're certain the carb circuit is spotless, the vacuum calps are new and tight and you have no joy a failing right side coil would be the next place to look.

I noticed that the fuel tank appears to be sitting beside the bike and the chrome instrument panel is still attached. I'm guessing the wiring is holding it there. You really should remove the chrome instrument panel and unplug the harness to prevent putting too much strain on it under the dash.
I'm really concerned about the number of cracks in the air box. If any air is getting in through those cracks, it is going right into the engine unfiltered. You might want to seal the cracks up with silicon.
Since you stated that you had spark in both cylinders the problem is more than likely fuel related (not enough fuel, too much air). Just follow Ed's comments.

I couldn't get the connector off. The tank is sitting on a box, so there was no strain on the cables to the panel.
I picked up some RTV today to temp patch up the cracks until I either replace the airbox or freak it.
Will work thru the suggestions, this week. I appreciate all the help. You all rock.

I'll check the intake "intake behind the air filter", you are talking in the rear of the airbox right?
I removed the CA emission hoses and put new caps on those three spots, not much of a difference so far.
Are swapping the coil boxes feasible? Or do they have seperate part numbers?

Each coil has 3 wires. Two regular 12 or 14 gauge wires and a high tension lead. If you swap the 3 wires on one coil with the 3 on the other coil and vice versa, take note to see if your misfiring condition changes sides. If so, you have just confirmed that a coil is bad. I can't see how this will help since you stated that both plugs fire.
Have you actually taken both plugs out of the engine, hooked them up to the high tension leads, placed them firmly against the engine and tried to turn it over to actually see spark at the electrode?

Yes, pull the air filter and look behind to insure that there's no blockage, critters have been known to take up residence in long parked bikes. You should also have four, not three vacuum caps. Two on the carb bodies and two on the manifolds.

I have the fourth as well. It was in good shape. Will check the air tonite.

Yes I have pulled the plugs and seen them spark.
So the coils are either bad or good? No intermittent in/between?

Like any electrical component the coils can show plenty of spark and still break down under load. That's the next test, once you're assured the fuel path is working as intended. Follow Gregger's advice and swap all of the coil wires side to side and see if the failure follows. The coils do fail and may do so intermittently, makes for an aggravating troubleshooting session.

So another day of troubleshooting and it looks promising. I pulled the air filter to check the box for clogs and leaks, but found nothing.
So I put the fin back on top without the airfilter and started it up, runs a bit rought with all the air flow. Covered the back fins with my hands about 90% of the opening and bamn, the right cylinder starts firing and I have good revs with no power drop.
So it seems I'm getting too much air. So i'm going to RTV the cracks in airbox between the airbox and the carbs, grab a new filter and see how it goes from there.

Really check the intake rubbers holding the carbs to the intake manifolds closely for cracks especially under the metal clamps.

Yeah no deal my CDI is still good. lol
Okay so I checked the intake hoses to the carbs from the airbox, pulled the clamp and it looks good.
Next I reset the pilot screws and turned them out 1.5 turns, ran but ALOT of popping at idle. Went to 2 turns, a little better, went out to 2.5 turns, popping is not so bad decent power, get a fair amount of decel popping.
Heres the deal if I reduce airflow into the vent of the airbox it mostly clears up. If I disconnect the single vacumn hose on the right carb closest to the carb it goes away. If I cap that nipple off with a vacumn cap the popping comes back almost immediately.
Runs awesome on the road with that vacumn hose disconnected and no cap. Sigh

I'm glad to hear your getting closer and it was not your CDI.
I'm curious where that one vac hose goes? Any idea?
Go to 2.75 and/or 3 turns and see how she runs.

I'm not sure it's CA emissions. I'll have to research it.

I'm not sure, if I remove the filter and fin top, I have no other hoses leaving the AB except the big ones to the carbs.
I do know the sensor tubes that are suppose to screwed into the heads are not there. They have bolt replacing them. Does this mean the AI has been removed?

If I recall correctly the AI hose enters from the upper left outside corner of the box. If that's not capped that could be your excess air input.

FYI. If you wanted to replace that cracked up airbox there is one in classified. May solve some problems. It does sound like a air/fuel issue.
