Heys guys I noticed some gas residue on the right side engine case. I have followerd it up and it appears to either be coming from the tank or the 2 carb. vent hoses that tuck under the tank. It isn't dripping on the floor but it has made a mess on top of the carb and under the tank. Any ideas? Before I take it all apart I was hoping for suggestions because I can't really see where it is leaking from.
Thanx

If i'm not mistake, I think there is a over flow hose that runs down the left side on the back of the raditor, maybe it came disconnected on the top of it.

Just my two cents..

 

Bio,
Thanx I will check that tomorrow. Any idea where on the tank it connects?

I have now idea where is connects under the tank.( on top i think). But i'm pretty sure if you follow the tube you will find it. Again this is just a guess on where it is leaking. Does it only leak when you ride. Or the carb is leaking out..

Just my 2 cents

 

Only when I ride. There doesn't appear too be any fresh gas as it has been sitting for a few weeks

 

It might be just splashing out that hole where that hose connects under the tank then. I would start their. I believe it is a vent hose for the gas tank. Bombardier DS650 does not put a vent hole on the gas cap. this why the hose is their.

 

When your bike is sitting, is the gas off? Mine had a strange leak when I would turn my gas on, turned out to be my floats were set too high from when I rejetted.

 

if it is the tank vent, pull the tank cover & you will see it on top. the vent hose is about 3 ft long & wraps around the tank. be sure not to pinch it or you will vapor lock. i vented the stock cap to be sure it would vent .

 

After further inspection it appears that it is oil not gas. It looks like it is coming from the crankcase overflow line that ends under the gas tank. I am thinking that I put too much oil in at the last oill change, correct?

 

Is the return line on the valve cover hard? If it is that is probably your leak.
