Any keihin carburetor gurus out there,please help?

[maicoman009]

 I recently take my "11" KTM-300xc to a Yamaha/Suzuki dealership to have new brake & clutch levers installed although I had to go get my bike back because they told me the levers are on backorder, no big deal I still have a 2 finger clutch & brake lever:-)
 My problem is ever since I got my bike back not only is my Li-ion battery totally dead but my carb is leaking out of the overflow hose steadily after I start the bike? I'm NOT a carb expert by no means but I drained the bowl & tapped on it lightly with my 14mm. wrench & sprayed some carb cleaner up inside the float bowl to no avail??
 Any help or advice would be greatly appreciated!..............

Don't drain the bowl, and give it a good wack with something like the handle end of a dead blow mallet. you want it to shake.

If that doesn't work pull the bowl and check the float needle and seat for some debris

Check and make sure the floats are actually closing off and stopping fuel from entering the bowl.

Had the same problem with the Keihin on my nephew's 250 TM last weekend and had to adjust the float height.

 Thanks guys.I really appreciated the advice & thanks a million jar944 after I read your advice I went out to my garage & used the end of a ballpeen hammer and low and behold it seemed to work great! No more fuel pouring out of the overflow & the 300 Katoom sounds great! I did'nt get to ride it yesterday but I plan on riding @ least a few hours tomorrow & hopefully I don't have anymore carb issues!.....
  I most definitely learned a valuable lesson & that lesson is NOT to take my KTM to a Yamaha/Suzuki shop just because they claim they can work on KTM's. They also told me when I dropped my bike off that they can now order any KTM parts no problem!? Well there was a problem when my bike was @ that shop for 3 & a half weeks & they said they will call me when the levers come in! LOL it's been 5 weeks & still no phone call about the KTM levers that they claimed they could get "no problem"    " title="Roll Eyes" class="smiley"> " title="Angry" class="smiley">   " title="Roll Eyes" class="smiley">

KTM can be very bad for sourcing parts from overseas. When I ran a spares dept,we would always try to give the customer
a delivery date when they placed an order.This was easy to do for Yamaha spares in the U.K.The other Jap factories were all pretty good. KTM,and Italian stuff is much,much worse. Dont bother ordering Italian parts in late July,or August,the whole country is
on holiday.

Order online from a stocking dealer like Munn racing, you get parts a lot faster that way.

 I've had very good service ordering parts from ktm-parts.com.They have'nt let me down yet,so far....

This is unrelated but it seemed stupid to start a whole new thread.

2001 YZ250 anyone got any recommendations for how many turns OUT with the pilot screw?

[VintageBlueSmoke]

Stu 1 and 1/2 usually.

My question to maicoman009 though is WHY DID YOU LEAVE YOUR BIKE AT A SHOP, KTM or otherwise, JUST TO PUT LEVERS ON IT!?! Please tell me it was there for somethnig else like a new bottom end or fork seals (or tire change) and they were just going to do the levers too...

[Stusmoke]

Thanks man, no wonder this thing is so erratic, the pilot screw was almost all the way out =0
