Bike suddenly running like ,

So I was taking my bike out after being gone for six month's (Dad was taking care of her while I was gone), Has brand new Carb's replaced not even a month ago, My dad has put 200 miles on her since the new carb's were installed, then out of no where today half way home she started running bad, Would cut out if I didn't give it gas when i was stopped, She was also not firing on all 4's, Above 4K She would just rumble back to life but as soon as the RPM's dropped a cylinder would die--Checked the Plugs-Fine, Spark Plugs wires SEEM to be okay but I'm also wondering if anyone knows if the Coils are known to go bad on these bikes as well---

Also NOTE: After checking the plugs and re-installing them I took her out again, everything seemed fine for a few minutes then she started down again.

Try Seafoam in the tank and mix per directions on the can. Maybe some moisture collected in the fuel system

That's not a bad idea actually, Going to replace the Spark-plug wires, possibly the plugs as well, Sea Foam is now on that list as well.

Are you referring to the 1977 KZ noted below your username? Whether or not that bike was prone to ignition problems, after 35 years anything could be suspect. Hopefully it is a fuel related issue and some cleaner will clear it up.

How old is the gas in the tank? Todays gas will leave deposits in the carbs and clog the smaller jets and orifices.

Seafoam and Sta-bil should become your very good friends..

Sounds like bad gas. Also, if it is the KZ1000...check the carb manifolds to make sure they were tightened correctly and check for vacuum leaks. Those boots get dry rotted and brittle which lead to cracks that cause vacuum leaks.

All good advise ^^^^
Bet you it's a fuel problem. Gas probably evaporated out of the idle jets and left deposits. If sea foam doesn't fix it the carbs will have to be cleaned.
There are 2 options...
Have it done by a shop or
Do it yourself and then take it to a shop because that didn't fix it, lol. Cleaning carbs is tricky and they should be synchronized after. Unless you know what you're doing a shop is the way to go.
Go see Patrick at Motorcycles Unlimited.

clean those carbs out really well, and if the bike is going to sit for more than a few days drain the carb bowls.

btw you do not always have to synchronize them if you leave attached carbs together.

It's true they do not always have to be synched but leaving them attached to each other is not the only factor to consider.
On a bike of this age it's very likely they haven't been synched in a long time and changes in the way the engine runs can mean it needs to be redone.
With multi cylinder bikes it is not unreasonable to synch periodically. I have seen bikes that were transformed just by synching the carbs. Idle was reduced, throttle response much improved and significant increase in power... All from just a sync.
Of course each bike is different and that won't always happen.

Anyway, clean carbs = good

I don't forget that FI bikes can benefit from syncing the throttle bodies.. still same theory of balancing the airflow into the cylinders.

Clogged petcock? U said it ran fine last time for a bit then started to act up. Clogged petcock will allow only a small bit if gas thru (not enough to feed it)
