getting frustrated, bike wont start again.

Run a hot wire to your coil feeds, forget the darn carbs until you know you have juice.

Quest, just to get it out of the way, when were your valves checked last? If they are tight, the engine will struggle to run, especially when it gets hot.

And +1 to checking the coils. I don't think it relates directly to your issue, but I had a 40 year old Honda that would run great for 30 minutes at a time. Once the coils heated up, they would crap out until they cooled down.

Mine ran like a top, never quit. Once in awhile it would not fire a lick to start. Turned out to be a weird hot wire to the coils issue, completely random. I got ****ed and went to a Dyna S wired as a stand alone system, even uses it's own dedicated switch because now I always know I have ignition.

Clean the carbs properly, check the valves, do all the basic maintenance or you'll be hurting. With that said, what's battery voltage with the key off? on? when trying to start?

Okay the last few posts are pretty much the same things I had suggested. What say you now?

Did I miss something I thought he said the bike just shuts down while riding and then wont start back up how is that a carb problem. Maybe a petcock problem but I don't see a carb problem here. I think he fried something jump starting it after he fixed the carbs
I myself have never ever had to dip carbs to clean them.

How many of the other posts mentioned his carbs as well? He said he sprayed them out and they look clean inside. He really didn't fix anything. Don't forget this is 30+ year old bike and some other issues may be involved in this as well.

The carbs might need more or better cleaning but he needs to find out why it is just shutting down first then make sure the carbs are right.
If he just cleaned the carbs and did not install a fuel filter he could have sucked some dirt in the pilot jet and that would cause it not to start but not just shut down while riding and not start back up after sitting for a while

And that's why I suggested he look at his electrical connections clean, replace etc and do a quick charging test. Process of elimination, remember air/fuel/spark.
It could be one of these or combination.

I guess we need more info also we have asked a few questions but he has yet to answer them. Rpm it dies at? How he jumped it? What is his battery voltage? Are a few. I assumed he checked all the electric connection after you said something. A lot of bikes will not run right with a bad battery even after it is jump started and if he jump started it with a running car I sure he cooked something

An old locally famous mechanic once told me that 90% of all carb problems were electrical. In other words, get the juice in order before you touch anything else. I understand that it's fine to go thru the carbs and a valve adjustment when resurrecting old stuff, but it's still all for naught if the fire is not reliable. I have purchased good stuff that the PO thought was shot because the electrics were screwed.

Yup, I agree. And he could have cooked something for sure. I cringe when some says they jumped their bike, I just say to myself, oh lord, hope what ever it was they jumped from was off at the time.

I jumped iy with a car what could be fried? How do i check?

Yes i did i did not take the carbs completely apart to clean them. But I didnt clean them because i thought that was the problem, i just cleaned them because i had them out while rejetting. Im almost positive the problem why its not srarting isnt the carbs because it ran perfect then just dies as if a plug was pulled or someone flipped the off switch. I dont know much about motors but if it was a carb problem it wouldnt ryn perfect then just die.

The bike would suddenly just die after running good. No putting or hesitation just die. Or it wouldnt start after running for a while. If i came back to it after a few hours it would start back up and be fine. It only happend a few times but got more often.

I bought a RR and it seemed to fix the problem. I rejetted it and had it running smooth as butter, road it for a few days and then it wouldnt start after a short trip to lowes. It finally started and i road it home. It Ran fine for a couple days then wouldnt start again. Next day started so I took it to the car wash. i tried to to leave and it had trouble starting. i waited a while then it started up but when i went to take of it just died and i had to push it home. It seemed to rev fine before it died but though.

Sounds like you might have fried your R/R. Did you have the car on when you jumped it? The extra voltage from the car battery will get shunted by the R/R to ground and you could have overloaded the zener diode in the R/R and fried it causing your battery to no longer charge.

Hopefully you didn't have the car running at the time. Even if it wasn't running you could have fired something, sometimes it happens and sometimes not, just depends how you lucked out. Remember a car battery has upwards of 500+ cranking amps. Compare that to your bike battery starting amps. When all those amps hit your electrical system on your bike, well bad things can happen. You probably need to check your fuses, connections, and RR. See if anything fused together, burned/shorted out. What type of RR did you buy?
