Carb Burble

[Lazarus]

To all you carb tuners out there - - what is the best way to get rid of a burble off idle (1/8 throttle)? I figure it must be slightly rich just at that time, so I looked into a slide for the Keihin PWK that would let in a tad more air and the cost was $155!

It may not be THAT much of an annoyance, but I would like to fix it.

Any ideas?

Adjust your air screw.

You must be paying KTM prices! I paid around $80 for a new slide. Other things that helped my bike pull cleaner off idle was dumping the factory reeds and putting a set of Boyesen power reeds in. Needle choice is important, expecially on a 250exc so you might want to check the jetting forum over at KTMTALK, there's a lot of good info there.
