Problem

[bergerhag]

How much fuel is draining out? Just a few drops or much more? You might have a problem with your float/float valve. Is your overflow tube routed up or clogged? This combination makes all the excess fuel from a bad seal on float to pour right down the crank case. Kicking it over with lots of fuel in there blows your crank seals. I had this problem on an old Husqvarna, where small grit in the fuel tank slipped by the fuel screens and jammed the float needle open, with a massive fuel overflow as the result. And it blew out my crank seal.

the over flow is not blocked its about an egg cup full mabye less depends how long ive been kicking it for.. does anyone know were i can get a new float needle from??? mine has like a ring round it so im guessing its worn..

me25690017 thats the gas gas parts number but does anyone know the kheien (carb make) id number? my local gasser dealer wants over 30 quid for one.. bit pricey i reckon

Any rebuild kit for a Keihin airstriker carb should work. Call around some jap shops or try and find one online. Probably find the whole kit for less than 30 quid.


EDIT, I just checked the RRP in NZ for a new OEM Kehin float needle, and they are 40 NZD ~ 20 GBP. So maybe about right if it comes in a gasgas bag??
It should be one of these float needles http://www.dirtguide.co.nz/products/...le_valves.aspx

Should be a PWK 38, measure the manifold diameter on the engine side to confirm.

Yep. If it overflows with that float height then the float needle is probably leaking, which isn't surprising after 12 years.
