Hey Dean, What else do you need to know about this bike? Here is what you need... get it while you can!!!!

Hey Dean, If the floats are plastic, they are preset,if the floats are separate, riding on metal "pins" and each float arm must be separately.. you will have to get a manual or http://www.mikuni.com/ and find the info you need.. if they are too low you will lean out.. if they are too high you will get gas overflow...(If you can't wait.. set them so they "FLOAT" high in the bowl..).. it should run ok, just leak gas out the overflow hose..

Why is gas dripping/runnng out bottom overflow line of carb?


Could be one of the carb floats is stuck or the rollover caused it to come off its mounting position. As fuel enters the carb, the float rises with the fuel level until it reaches a position that shuts off any more fuel entering the float chamber and prevents an overflow. Fuel level drops, float drops and fuel flows again. Basically like the cistern in a toilet.

My suzuki gs400 keeps overflowing with gas from the breather tube! the carbs have been checked and this keeps hapenning?


This still sounds like a carb issue to me. 2 likely causes are incorrect float height and, most likely of all, a sticky float needle. Did you get a dealer to do the work? If so, have a go yourself, its not difficult if you take your time.
First, try gently tapping the carb float bowl, this may (but not always!) stop the overflow and clearly indicates a sticky float needle. You need to remove the carb that overflows (or both). Remove the float bowl (usually four little screws). Looking at the bottom of the carb, you will see the float assembly. This works just like a 'toilet'. As the float bowl fills, the float rises and eventually shuts the float valve (which stops the fuel flow from the tank). Remove the float assembly (normally held in place with a pin). Under the 'tang' on the float will be the float needle. It will tip out easily. Check its condition. Also check the float seat. Make sure both are clean, unmarked and spotless.
Be very careful how you take the carb apart, it is a cast assembly and not very strong.
If the float level is incorrect, then you need to adjust the 'tang' on the float assembly to adjust this. You need a manual to do this Im afraid for the method/mesurement to set the float to the correct height.
Good luck!

I have a 03 Yamaha 660 raptor one of the carbs


Did you reset (adjust)the float inthe float chamber to tht carburator which is leaking ?
You will probabley have to adjust tht float to stop from overflowing in other words we call it flooding.
Check the float pin of wear at the tip.
Hope this helps!

Just need the height setting for the floats the


YOU CAN ADJUST FLOATS WITHOUT SPECIAL TOOLS. ALL YOU NEED IS A FOOT LONG PIECE OF CLEAR TUBING, SIZED TO FIT THE BOWL DRAIN. SET FLOATS AS CLOSE TO WHAT THEY WERE WHEN YOU REPLACED IT. INSTALL THE BOWL AND PUT THE TUBE ON THE DRAIN. OPEN THE BOWL DRAIN SCREW WHILE HOLDING THE TUBE UP BESIDE THE CARB. WHEN YOU GET THE TUBE BESIDE THE CARB ASSY., THE GAS IN THE TUBE SHOWS YOU THE EXACT LEVEL OF FUEL IN THE BOWL. FROM THIS YOU CAN MAKE ANY ADJUSTMENTS NECESSARY FOR CORRECT LEVEL. THE LEVEL SHOULD BE RIGHT BELOW THE PLANE WHERE THE BOWL MEETS THE CARB BASE.
