my trailfire 440 has some problems right now and i cant figure them out! i will pull it and it will start in 3-4 pulls and sometimes it will idle but then when i go to give it gas it just boggs rite down and if i let off in time it will stay running but still wont move and when its idling it engages the clutch and trys 2 jerk forward over and over i have to hold the break, but its snowing here and i want to get this fixed and i knew u guys here would have some good advise for me to try so ill be waiting for ideas but thanks everyone and happy riding to all!!!!!!!!

If the primary spring is broke, you may be able to move the spider essembly in & out ( with the engine off ) . The primary spring holds the clutch open until the force of the weights is greater than the spring. If the spring breaks, the weights will close the clutch, engaging the belt prematurely. That would explain the belt engagement at idle.

i think the engine may be reving to high tho. i dont have a dash or rpm gauge so i dont kno if its reving to high it sounds like it is reving a little high tho.

unfortantly that isnt always the case with broken spring i had one where you couldnt push it in and out but still engaged right away.

rpm should be about 2500 when idling. if your way higher than that your throttle body cap may have come loose and or the cable is funky.

On these sleds you can look directly at primary clutch spring to visually see if its broken. take a look.
