Sound Like A Dream - It Could Be Yours.
The Bumph...I have been developing this needle since 2002.
I did over 120 test runs to perfect it and so here it is!
This jetting kit is supplied with instructions, and once fitted and tested, will make your Husaberg or KTM a log popping trials machine.
It gives the bike a crisper throttle response with no bogs
and improves the fuel economy as well.
It's easier to re-start, idles very smoothly, pulls off inspiring confidence that you won't 'stumble'.
It makes the bike easier to start when warm.
There is no loss of any performance.
It isn't tiring or too powerful it is simply far more responsive - it happens when you ask for it. It suits all Keihin FCR carbs, Mk1, Mk2 as well as a ‘production carb’ if used from other bikes.
37/39/41mm, retro fitted or OEM, 400 to 650, it’ll work, all we need to know is what you have?

Please state when purchasing the: model/CC and altitude, year, standard or tuned, exhaust system? The kit comes with the following: A needle, an extended pilot screw, two pilot jets, a pilot air jet, a main air jet, 3 main jets, an accelerator pump limiting spacer and instructions.
