Product Overview
A Bear Tracker that has sat with fuel can end up hard to start, lean off idle, bogging under throttle, or overflowing from a stuck float needle. Once valve clearance, compression, ignition, petcock flow, intake boots, and tank vent are checked, a complete carburetor can get the ATV back to predictable trail and chore use.
Yamaha used year and market suffixes, so compare the old carb body and number rather than relying on the YFM250 name alone. Check the 33 mm manifold-side inside diameter, 46 mm air-filter-side inside diameter, cable/linkage layout, choke, and fuel/vent nipples.

Compatibility Notice
Northline Parts does its best to list all known compatible models, but the correct part may fit an application not shown.
Model, production date, serial number, engine or equipment configuration, installed options, and previous repairs can affect fitment. Compare the original part, identifying numbers, dimensions, connections, and mounting details before purchase.
Frequently Asked Questions
Q: Why does my Bear Tracker only run on choke? A: A restricted carburetor is common, but poor fuel flow or a cracked intake boot can also make the mixture lean.
Q: Will this fit a Big Bear or Timberwolf 250? A: No fitment is claimed unless the original carburetor and listed 4XE numbers match.
Q: Do the year suffixes matter? A: Yes. Compare the exact YFM model suffix and carburetor layout for your market and year.
Q: Should the jets be changed before use? A: Start with the supplied configuration only after confirming the application; altitude and engine modifications may require tuning.
