So i have a 2000 polaris xpedition and it runs good at idle until i ride it for 5 minutes and then it idles super high and leaks gas out of the float bowl overflow like the floats are stuck. Ive cleaned it 4 times now ran seafoam through it and still have problems. Any ideas whats wrong? Thanks in advance!!:confused

 

Cleaning carbs doesn't always work.Install a carb kit as the old needle and seat could possibly be sticking causing the problem. Plus float level could be off. http://www.ebay.com/itm/100-MIKUNI-CARBURETOR-CARB-REBUILD-REPAIR-KIT-FOR-POLARIS-2000-EXPEDITION-425-/291422699046?hash=item43da257e26&vxp=mtr Plus even a worn float pin or float in the area where the pin goes through can wear over the years and bind and stick. Not included in the carb kits if needed.

It must be the needle and seat because I adjusted the floats and it still does it so should I rebuild the whole carb or the do the needle and seat? All the other jets are fine

 

Cheaper to get the whole kit as the oem needle and seat alone is $36 through Cycle Parts Warehouse. 8 bucks more you can have it along with a new float bowl gasket and new jets.PLUS remove the float pin and see if it's worn down.. If it is, order a new one. Hopefully the float arm assy is ok.

 

Should i buy oem? Or something different?

 

If you look at the listing on ebay a little closer at the bottom of the page, it shows that all parts are genuine Mikuni brand replacement parts.

 

Alright i finally figured out how to get the floats off took forever but got em off and it was a dirty needle and seat tgat caused all my problems

 

Just get the kit and save some misery!! You don't want to have to go back in again on carbs more than once..
