Greetings Husaberg community, thumbs up on the site, was wandering if anyone could help me with a slight carb problem. I've got a 04 FE650E and have done the mandatory first time oil change over fill resulting in a nicely oiled carb. Now I've cleaned out the main jet, slow jet and that other jet next to them but it still won't start. Anyone know off any particular areas I should pay attention to when cleaning this carb.

It's monday now and I have to have it going by next weekend so I can take part in some high speed hooliganism.

How much did you overfill it? What does the spark plug look like? I would think the carb is ok as long as you put it back together properly.

I'm not sure how much I over filled it, all I did was drain the oil out off the oil hole then put a litre in. Next I'm riding along for about and hour then I hold it flat for a while, turn it off and have trouble starting it, turn it off again and then it won't start.

Next I tow started the thing and it's running like a hairy goat, like a twin cylinder running on one cylinder, won't idle but it runs alright when I flatten it.

Anyway the inside of the frame is coated with oil and so is the bottom of the float bowl. Any idea's?

The crankcase breather venting some oil mist into the frame and then through the carb is a normal Husaberg phenomenon and should not cause you any grief unless you flip the bike. Ingesting a little oil is of no consequence and should cause no harm. Some oil does tend to collect at the carb to frame rubber boot but a few blasts of WOT will suck it right through. When cleaning the airfilter wipe the oil out with a rag or paper towel. I would venture to say that the problem may not be carburation but more likely an ignition problem. Did you put a new plug in? Use a new plug and ground it against the cylinder. What does the spark look like when you kick it?

Same old sparkplug gapped and cleaned properly. It's got a good strong spark turning over off the starter motor. I thought it might be the some blocked jets because it runs alright on the main jet but runs like crap when it's not on WOT and won't idle below about 3000rpm.

1 litre should not cause that problem. I think you need to look further. Maybe a stuck reed valve or even piston ring. Check and make sure the foam insert is in the breather hose as well.

Look at the air jet that bleeds air into the needle circuit to froth the fuel. That may be plugged with oil. It is in the intake bell of the carb. This can be a problem on Carbs if the air bleed is at the bottom of the bell. Not sure if it is located low on an 04 or not.

Read sir Taffy’s document. :wink:
One of the first things you do with a new Husaberg is to reroute the breather hose engine.

Took the thing back to the husaberg dealer and turns out I broke an exhaust valve spring, first one they've heard of with the conical valve springs. No damage and 20 bucks later and it's all go.

I was just told about a neat little trick by Jim at MotoXotica. In the event you drop your bike, you can prevent large amounts of oil getting into the cone shaped rubber breather connection and then into your carb by simply stuffing something porous (like UNI filter medium) into the wide mouth end of the vent (maybe 1/2". 3/4" or even up to 1" thick...cut to fit). This will still allow proper venting/breathing, but prevent a large slug of oil entering the airbox/frame if the bike is laid down.....at least for a minute or so. This should give you enough time to collect yourself and right the bike should you take a hard fall before any large amount of oil ends up in the carb.

now that is a great idea! especially for me since i seem to spend more time on my seat than the bikes

My bike came with one also. It hasn't failed me yet, despite several inverted episodes.
