Fuel in Crankcase..........help!

I decided to put my 86 FZ600 back together this week (in pieces for last year and a half). I put the carbs back on and hooked up a home made IV bag for the fuel as the airbox is still removed (Funnel with a hose directly to the carbs). The bike started right up but blew some smoke at the exhaust and was popping once in a while from the exhaust. I also noticed that the fuel was going pretty quick from funnel.

I suspected exhaust leak at manifold was cause for popping noise and removed the pipes to discover the last bozo that put it together never put any exhaust gaskets in. This was good though because I figured this would fix my problem. So I decided to change the oil while I had the pipes off and when I pulled the drain plug the oil just poured out (engine is cold), I smell the oil and there is probably about a litre of gas in with the oil. :nono:

I pulled all the carbs apart and cleaned all the jets and checked the floats etc. I put everything back together and hooked up my IV and again I have pooling fuel in all four carbs. Does anyone know whether the root of my problem could just be the stupid IV I made up? Is there something different about the fuel coming from the tank petcock instead of from my funnel deal (funnel cause to much pressure?). Any help or info would be appreciated.

My guess is the floats aint floating and the gas is just flowing.

Have you checked the weight of the floats to see that they aint wet?

Are the needle valve seats perfect?

I'm shooting from the hip here, pure guess work not being there.

I had a problem similar to this on my XJ550. Since my petcock leaks just a tiny bit when it's set to ON, the bike sat for about a week in my driveway, the fuel was filling the carbs, and the needle valves in 2 or more carbs were sticking open because I accidently scratched them when I cleaned the carbs. I ended up with about a gallon of gas/oil in my crankcase.

Get yourself a carb rebuilt kit complete with the needle seats and needle valves and install them with just your hards to prevent scratching. That will stop your problem.

Hi, my name is Zanidy O'Dallieser, and I was just reading over a post that you left back in June. Just by reading this, I could tell that you knew your stuff about bikes. Well, I've got a crotch rocket and I'm needing to replace the starter clutch and idler gear. (Atleast that's what I've been told)... I keep hearing that you need a certain tool to do such a thing...


Can you help me?

If you were referring to me I'm sorry but I can't help you. I'm very familiar with my old yamaha xj because it's my first bike and I basically had to replace and tune everything except the engine to get it running. I don't know much about newer bikes with fuel injection and water cooling.

Honestly I highly recommend you pick up a service manual. Working on your own bike can be very satisfying, and very cost effective. The book will tell you what tools you need, and the procedure for doing the repair. Clymer makes good manuals, I used one exclusively for my XJ. Ebay has them for a fair price:

That might be the one you need.
However if you need any carb tuning advice or fork seal replacement, that I do know about.
