1982 gs1000 kat, rough idle

[Escobarclan]

Thanks for the great welcome guys. I originally posted this in the wrong place, here's my dilemma.

1982 gs1000 kat, ran good for a good friend (bike dealer and mech too), then stored for a year. He said it ran good when he got it, and his word is good, so i dont think it's the valves.

4,000 miles, good plugs, wires. Boots in brand new condition. Bike runs good on choke, then rough idles (popping, backfire, rpm variance). I took the carbs in and he 'cooked em clean', with a little varnish coming out.

Got pods for intake, they were already on and new.

Love this bike, gonna post pics soon.

someone may have over oiled the new pods.

When you friend "cooked" the carbs he didnt happen to note what jets are in there did he? Is the popping through the exhaust or the pods??

Idling problem

Popping is through the exhaust only, with the idling going high and low for no apparent reason.

Sure sign of a vacuum leak, or out of sync carbs.

checked vac

Ok, checked for a vac using carb cleaner for a response around the intake & boots, nothing, as for the carb settings, nothing has been touched. It ran fine with the seller(he's a good friend), but now its not. It was stored for a year though.

This may be something, I didn't try to start it until after I sent the tank in for painting(getting it back today), so when I ran it I just put on a much longer fuel line and used a massive plastic syringe to drip in fuel as needed. It ran bad as it does now, but would idle up as I put in gas. So to keep a steady stream I attached a 2 gal. tractor gas tank, same line size and all. It ran alot better but I still have rough idling and exhaust popping.

Since I got it 2 weeks ago, I've gone through every square inch of the bike, cleaning and never messing with anything mechanical or carboration.

I'm just stumped. Thank you for the feedback Nessism
