250-500cc 08 WR250 Float Height

Is this correct 18-22mm? Adjusted mine but seems awful high on TMX carb.

Thanx!

That's what I've read here as well as other sites. I dont have a manual to truly verify though.

What did yours measure at stock?

Mine after started 1st time this year had gas coming out of vent hoses. They were so low in bowl that they were not shutting fuel off. I wondered why I had to refuel every hour to hour/15mins. When I went into a turn it was leaking gas.

Thanx For The Help!

I dont have a caliper to measure, but I can tell my float height is way off by eye when I removed the carb and dropped the bowl today.

Invaluable info.

I dont bother with calipers. When the seam of the float is parallel to the carb bowl mating surface then its golden. An old factory Kawi mechanic taught me this.
This pic shows a perfectly calibrated float IMO:

The seam and the bowl mating surface are perfectly parallel.

Read carefully about not allowing the bumper spring to fully compress. Hold the carb at 45 degrees to accomplish this.

Awesome PC/K. I set mine @18mm and is alot higher than this (Concern I have). At first I set it like the picture above, parallel with bowl surface. My main fear right now with the 18mm setting is that the bike will have fuel starvation on a straight away. That means production will go down and the price of gas will go up? Or is it, consume more and the price will go up? Or is it just going to go up?

I am going to go back and change mine plus check the needle and seat. Make me wonder if my shipping crate was dropped at some point?

Mine was way off too. I didn't measure it with calipers, but I broke out the tape and it looked to be about 9mm. I adjusted the tang so the float seam was parallel to the bowl mating surface and that put it around 14mm, which is still 4mm off from the Husky spec.

Bike ran great, but drank fuel like a thirsty pig. Or maybe I was riding too many roads at WOT

I guess I'll try it at 20mm (middle of the spec) and see what happens. Maybe the 'seam lined up with the mating surface' trick doesn't apply to these TMX carbs!?!? It runs fine, but seems to be using a lot of fuel.

You better get a handle on that extra consumption or your going to make the gas prices go up!
I ran mine over the weekend, leaned it over and had no gas come out of the tubes.

Thanx
