Reasons my bike would go to twin mode

[timebombprod]

I know exactly what it is. It checks for an internal electrical short between phases. The reading should be ZERO.

So the test I did failed?

I don't know what you are doing.

The output test is done with the engine running and measured in volts.

The ground test is done without the engine running and is measured in ohms.
For a heavy wire, 3 phase stator, the resistance should be approximately 0.1 ohm or less, or nearly zero.

Sorry I just dont know what i should get from a stator ground test I just know it was something I needed to check

[timebombprod]

Okay I have to find what a ground test would be. I know I passed the output test, I also checked resistance with the bike off just checking all the stator legs and it was at .6 for all of them.

I thought the ground test would be one probe on a leg and the other probe grounded to the engine and checking acv for that, that's where I got the 50 acv from, if I'm doing it wrong or reading the wrong number let me know.

Engine not running and ignition switched OFF.

You've combined some right and some wrong. heh Set meter to ohms, lowest setting that is greater than expected reading. In this case set meter to measure 0.0 to 0.5 ohms range. Place one probe of meter on a leg/lead and the other probe to engine case/ground. Expect a reading in the range of 0.1 to 0.25 ohms.

When you cleaned the four carbs, did you clean out the 56 orifices/ in the 4 spray bars with a wire bristle?

[timebombprod]

No wire bristle, just used carb dip, ultrasonic cleaner, with all the pieces separated, anything that involved rubber or plastic was in pinesol.

Rinsed all parts with warm water and wiped dry and assembled back together.

[timebombprod]

Lowest ohm reading on my multimeter is 200 but I do get a reading of .8ohms across all legs configurations. Gonna call Rick's and see what they say and possibly get it returned.

Seems that its definitely higher than it should be

I agree with you.

I think you should take the cap and float bowl off the #4 carb, remove the main jet and with a dowel, push the spray bar out the bottom and inspect the 14 holes that are in the sides of the spray bar. I would not be surprised if they are clogged.

Yeah i will be technically rebuilding them again tonight just not doing a dip since they're visually clean, will be using carb spray and also compressed air. I'll make sure to poke all jet holes again.

My.bad.i didnt realise what you meant but yes I always pole through the holes. The difference this time is I'm cleaning the airbox aswell so nothing passes through there possibly obstructing the carbs

[timebombprod]

Carbs done, airbox cleaned, and it's close to 5am so I'll probably go fishing. Hopefully this works this time. I went ahead and changed mains back to stock seeing that from my post asking about an exhaust that theres no reason to upsize jets, my 1/3rd to half throttle was a bit choppy but if I gave slow throttle it climbed smoothly. We will see if anything happens.

The carb passed the circuit test fine, blew compressed air and carb cleaner from mixture hole to backtrack the circuit instead of possibly pushing something more into where the circuit reaches the mixture area. I sure hope this is the last time I have to mess with the carbs for malfunctioning reasons

Months ago, you said you had replaced the plug wires from your existing ignition coils..if this is still true, I’d get an eBay set of used Suzuki ignition coils and try them. I think your “twin” problem is ignition related

[timebombprod]

No it is definitely the carbs, I have replaced the coilpacks and i run on 3 cylinders great right now, have to see if the fourth one works today. I get consistent and strong spark on all 4. The short circuit is somewhere in the charging system it was never my ignition system lol. Good that it was all replaced but damn I'd have saved alot of money if I knew where it originally came from

I would be willing to bet money the charging problem and R/R's consistently burning out is related to the ground fault in the stator. I think a new stator is needed and I would not be inclined to reinstall an old one. But for now, leave it be and disconnected since it does not apply to your problem with the carbs. Lets fix one thing at a time.

I've been rereading all the posts in this thread, analyzing what you've said and what you haven't said. I'm about 95% certain I know what the problem is and how to fix it. When you get back from fishing, PM me. I want to get on the phone with you. The explanation is a bit lengthy, I can say in five minutes what it would take me half a day to type. This is too slow and you can't ask questions, etc and get quick clarification of things I need you to do.
