RF600 Gas Leaking From Carbs...HELP!!!!

Ok thought I would get the bike out one last time for a spin before winter really hits . It was almost 60 degrees yesterday and a great day to ride around the block a few times. Anyway put the battery back in the bike and tried to start it. Would not fire for anything. Finally after cranking and cranking it fired but only a couple of cylinders. Next thing I know there is gas pouring out of the overflow tube going to the carbs and looks like gas running out of the air box. As far as I could tell without taking off all the fairing and tank to be sure of where it is coming from. Does this sound like maybe a stuck float on one of the carbs? Anyone have any ideas I would appreciate it. Its a '94 Suzuki RF600. It has only sat for about a month since the last ride before it got too cold.

Stuck float or stuck needle jet.

Time to pull down the carbs for a rebuild / cleaning

The guy I bought the bike from said he had a shop rebuild the carbs last year. Should I rebuild or clean and if I just clean do I have to completely tear them down?

I've never re-built carbs... or even seen them... save from pics... but he could have screwed something up putting back together...

Does your RF use a fuel pump? Does the petcock have a Prime position? Does it have a fuel filter? If the RF uses Mikuni carbs, and the previous owner used a cheap rebuild kit, it could have brass float needles instead of viton tips. Most likely one or more float needle/seats are clogged or leaking.

The bike ran great this last summer. I put around 4000 miles on it just this summer with no problems. Yes the RF use a fuel pump, no prime position, and yes to the fuel filter. The bike does have Mikuni carbs. Sounds like I am going to have to tear them down and see. Why use viton tips instead of brass? Never heard of the viton tips.

Brass tend to clog and are infereor.
