I have a 99 trail boss 250. It had been sitting for years and I had a guy put new jets in it and new needle and seat. Now gas is dumping out the vents and wont stop unless I turn the gas off. Is something stuck in the carb or if the hoses are in the wrong place will that mess it up? Thanks Matt

SOURCE: 2001 Polaris Trail Boss 325 ATV. Why doesn't it go more than 20 mph?

My guess is that Chinese carburetor is not jetted or set up right. It may not even be opening fully. Ask in the Polaris forums. Top speed should be 45 mph.

Do i mix oil with the gas for a trail boss 250

Is the engine a two-cycle or four-cycle? A two-cycle engine requires oil to be mixed with the fuel to lubricate the piston/rings/crankshaft/rod top and bottom bearing/main bearings.
A four-cycle doesn't require it. (A four cycle has valves in the head)

What year model vin 1563339 polaris 250 trail boss

thats not enough characters to be a proper VIN you should have 17 numbers/letters and the 10th digit will tell you the year. The VIN should be stamped in the neck of the frame. If your find the whole number I can break it down for you.

Does a 1992 polaris trail boss 250 2x4 need a cooling fan, once ido find a used one how do you wire it to this bike

A 250 probably doesnt need a cooling fan unless you're hauling heavy loads slowly in hot weather.
