    You guys are bad karma with all your talk of carbs lately!
    Since I got back from a ride on friday I've smelt fuel from bike. Pulled the bashplate off this morning to find where it was coming from and found it dripping from the hose coming from the bottom of the carby. Would this be the float stuck?? If it is, is it just a matter of taking the bowl off and giving it a helping wiggle? Also is this a sign of other problems?

    Thanks guys!!!

    I cut out a round piece of foam, oil it and insert it into the top of the breather filter, works real good and can be changed easily and often :thumb

    Make sure you clean and re oil that carb vent filter every time you clean your air filter.

    A tm40 doesn't have this problem ;)

    That's just because you can maintain a ktm while fixing the crash damage. I fixed the brakes and t-ed the carb vent lines on the dr this weekend, so I really want to take it for a ride between now and then.

    had a similar issue a while back but mine was filling up the airbox with fuel. in my case, i had to pull the float assembly off and replace the small rubber o-rings. not sure if it will be the same thing on yours. happened on a bike less than 6 months old... next guess would be the float level.

    go to an auto shop and order a diff breather filter for a 4wd
    K&N make one same size as the stock POS
    once i replaced the filter on mine i didnt find dust in the slide anymore

    You should not be attempting to compensate for incorrect jetting by drilling the slide.

    Replace the breather hose filter with a UNI UP-123.

    I think it just depends on whether or not you have the inclination/time/skill/patience/money to tune the FCR properly. I think if the FCR in question has a TPS, there is little question which is better. Plus, the TM doesn't have a roller slide, which means the slide and body will eventually wear out. Of course, then there's the TMR, which is another story.

    Regards,

    Hello Mark,

    The likely culprits are: a piece of dirt stuck between the needle and seat, deposits on the needle seat, a worn/damaged float needle (look for the tell-tale witness-line under magnification), and/or a dried up/hardened/deformed/cracked/otherwise damaged needle seat o-ring. It is rare for a float to stick or for a needle seat to be damaged (beyond having deposits on it). Don't forget to seat the float height & set the idle mixture & speed after you've fixed the problem.

    Regards,

    Derek

    It is not possible to cause the carb to overflow via a misadjusted float height alone.

    Regards,

    I fitted a unifilter breather to mine and the next trip copped a lot of rain overnight and the next morning.
    The bike developed a severe flat spot. This was caused from water running down the back of the tank onto the filter and clogging it.
    To fix it I cut a plastic cover out of an oil bottle that hooks over the top of the breather to keep it dry.

    Hello Derek (Motolab);

    Could you please give us baseline jetting of the BST to give clean running, good acceleration and acceptable fuel milage? My bike stock got 18.3km per litre, now I get 22km per litre with much better acceleration and still clean running. My header is ground, no snorkel, extra 38ml. hole drilled in top of air box, slide drilled and needle off shelf in richest clip. So far you have told us what not to do, so please tell us what we should do. Thanks for your time.
