My bike always leaks gas when fully laid over as any kehien carb does in my experinece with huskys and husabergs, but lately my bike leaks gas out the vent tube when I lay the bike over only a little bit. A guy rode behind me and he says it was dripping gas as I went around corners and believe me I can't rail nothing. I rail a corner like an old lady . so what about the carb is wrong.....is it my float bowl thingy stuck? what part needs to be inspected cleaned or replaced?

thanks

Thanks for the plug Ned,

Bob, if you go to the SUDCO web page and look at the carb diagrams, then look at the FCR MX new!, find part #37, that's the O ring we are talking about.

It could possibly that your float level is set too high. If it's not dripping when you are sitting still then I doubt it's the O ring on the needle seat.

Have a look at your manual and it will tell you where the float level is supposed to be. It is normal for the overflow to be wet and drip when you are riding, just not excessively.

You have to remove the carb completely to check the float level. I tried to do it on the bike and got it all wrong, you need to use the procedure they describe.

If you need any help, let me know.

cool, thanks. I'll report back. This time no pencils, I promise.

LOL!!!

Bob,

Just for clarification, it's the overflow tube that comes off of the bottom of the float bowl right? And not the actual vent tubes themselves.

Ya, Dale likely has the solution. Float level over time go out of whack from repeated bouncing and the odd "tipover". Typically, they always richen the mixture and fuel spillage. Thankfully, being that the floatbowl is on teh bottom of the carb, when you break the pencil lead off attepting to adj the float tang, it will drop into onto the starter and out of harms way. So don't worry, I don't think there's any worry using your lead.

Good catch Dale. I just bought a used FCR 39 (MK1) fitted it to the bike and noticed that 1, I can't keep it running for the life of me; and 2 the over flow tube coming off of the bottom of the bowl has a drip. The drip is about 1 every 2 or 3 seconds. I was going to go out and adjust the float but now I'm curious if the o-ring is spent. I know it's a difference in carbs because I threw on the dellorto and the bike fires up and idles like usual.


In case the question were to be asked; I cleaned the passages prior to installing, and my jetting thus far is -
MJ 155
MAJ 150 or so can't remember at this moment
PJ 35
PAJ 55 (3/8 turn PAS)
FS tried everything from 1 turn to 2.5 turns in 1/4 turn increments
Needle DMS (clip #2)
Starter Jet #75

with the bike on that jetting@ a standard plug will last for just one ride.

i'll repeat that. A STANDARD PLUG ON YOU R JETTING WILL LAST FOR ONLY ONE RIDE!

you must go to a quality plug. do other things for sure but the plug is a must. i love the IXU24 and won't change because it is already 100%.

zis is an order!

I'm going to change the o-ring and float valve and call it good. I'll follow your lead on the plug too.
