Well my 250 was having problem goin past half throttle wouldnt open up, but it improved wqith some mix gas but still does it sometimes now but i think its the throttle sence my aunt smashed it into a tree and ended up ion the hospital, she blacked up but says the throttle stuck forcing her to slam into the tree, she had brakes on but i have them tight and they ar epretty hard to ppull, anyone know what might be causing my problems?

 

mixed gas wouldnt have any thing to do w/ how it performs. maybe the carb the main jet is partily plugged. need more details on what its actually doing. systoms of what its acting like.

 

basiacally you push the throttle down and it goes real slow like less tehn half throttle and it get a weird noise comin from it like its missin or something, its very hard explain, like it sorta chugs, like if a car is runnin on half its cylinders

 

You know. Almost sounds like it's doing the limiter thing liek it does in REVERSE where you need to hold the override to get FULL POWER...

What if, for some reason the switch for reverse is stuck/worn and engaging that limiter even in forward?

Try holding the OVER RIDE button on the left handlbar and see if that gives it full power.

 

I had a trail boss that was doin that and it was hard to start the mechanic told me to unplug the ETC going from the throttle i believe its a black one..try that too just my 2cents

 

It's a safety device in the throttle. If it comes out of adjustment, it tries to kill the motor in case of a wide open stuck throttle. Pop off the top cover by the thumb throttle and you will see some contacts. I can't remember which way, but adjust the cable so that the contacts are open(or closed) when you accelerate.

 

well thanks for help but it seemd to straitne itself out....got alot of smoke poyrin form the exhaust now though, but i cant do anything for awhile sence when my aunt hit a tree she kinked the axle so i gott replace but thanks for help everybody
