1997 yamaha mountain max 700 runs but then boggs then runs normal again

The sled starts up nice with choke on, runs good lots of power then all of a sudden it has no throttle. I will sit and idle but when you go to give it throttle it boggs down and wants to stall out. If you wait a couple of minutes it will be have full throttle again. I likes to run with the choke on all the time

SOURCE: eng runs with choke stalls at idle with choke off after a couple of minutes

Jets are clogged. When the choke is on you cut the air and the mixture is good, with it off to much air. Dont know the carb you have but the low rpm jet is clogged. should clean the whole carb. Gas will gum up in 6 months if not treated with some stableizer.

Idle problems after throttle is closed fast.

sounds like an overly rich condition when you let throttle snap shut no air enters or at least minamal air enters the engine and with to much gas the engine will bog down until the extra gas burns off(5 seconds) check floats height and make sure jets are secure and make sure the choke is all the way off
