Hey guys, any chance someone has pics showing this? None of the links work and the old pics are no longer there. Need some help as the 250 is pissing fuel out the vent tube when the fuel is on.

Not sure where to measure float height from?

If the level is right and its still overflowing double check the viton tip on the float needle. Sometimes they perish, othertimes they just have a bit of grit stopping it from sealing.

I just fixed the float level on a kdx last week where the factory specs werent right for that carb because the needle valve seat needed to be altered. Long story short I made a fuel level guage out of tubing and a stopper. The gas goes up the tube to about 2 mm below the mating seam of the carb bowl.

Thanks Jake - that's much better than the one I ended up finding:

Definitely appreciate the close-up shots with text on 'em - that guy did a good job.

It ended up being the viton tip...sort of. Did you know that if that piece doesn't go back into the fuel inlet that the bike will piss fuel like it's raining

Yeah...should always remember the KISS principle when something goes pear-shaped...lol.

HI guys, I'm a new Italian Gasgasser
I've got a 2013 ec 300.
Just a problem: white plug with 40pj N1EF SECOND CLIP 175mj

After slow riding the plug is black and wet but after 300 m fast uphill become white and dry.

The bike runs good but in the long fast uphills there is some lose in power or little bogs ( I'm not sure about the last term ).

The bike was brand new but the mechanic set the float before deliver it to me.

Yesterday I checked the float level and I found between 8 and 10 mm so I hope I found the trouble.

It's more difficult to adjust the float in new PWK vs Mikuni tmx because the pin is so close to the tab the I can't see exactly when the contactoccur.

I hope I have lowered the float up to about 7.5 mm.
The bike does not pay gasoline up to high inclination, do not understand how others do to say that pours on the stand.

If not fix the problem I'll try a 185 mj....

Other ideas?

Thank's

Just read the last one. Im too lazy to go back. Somwtimes irs mant posts back.
My suggestion is try a 180 first. Then 182. Then 185. You may be jumping too far with a 185.
That is if you havent already tried it and posted it above.
