jetting problem?

[baker]

wasup guys? my shee is undergoing a rebuild so for now im tryin to beat on this warrior i got, its got a 400cc streetbike motor in it well it runs great in neutral but when you try to ride it it kinda pops and sounds like its sucking air-boggy sound- its got somewhat open filters on it kind of like a k&n for bikes, i checked the intake boots they have some small dryrot cracks on the outside but the insides look fine, i cleaned the carbs and the jets still no help. any ideas what i should try now thanks

well, does it have the same intake and exhaust restrictions as the bike it came out of, and did it run with the current jetting and setup before? also, if it is alot colder, it will be leaner. something as simple as removing the muffler baffle can significantly change the jetting, just like a 2 stroke.

Just because you don't see any cracks in the intake boots when they're sitting there doesn't mean when the motor is running the rubber isn't flexing and causing a crack all the way through to open up.

Use carb cleaner and spray the intakes down at idle and with the throttle cracked open to double check can make sure the cracks aren't all the way through.
