Why does your exhaust pipe glow red on your Yamaha warrior?

Wrong size jets...possibly. Otherwise this answer could not be further from the truth. Most likely cause is that you are running lean (not enough fuel/too much air). This could be caused by the wrong size jets, but if you have not changed them, I would look elsewhere. A clogged fuel filter could be to blame. That would be the first place to look. Next I would look for a leak around the joint from the carb to the engine. Spray starting fluid...or WD-40 around the joints and listen for a change in engine RPM. This would indicate a leak. Then I would check the carbs. I don't know how much adjustment can be made to yours, but mine allow for none. You might just have to rebuild the carbs...but the problem is NOT a flooded carb. Happy hunting.

theres unburned gas in the exhaust sounds like the carb flooding or has the wrong size jets
