My budy has an old Polaris Cyclone 2-stroker and it idles fine in neutral. When you go to shift it into gear(its an automatic) it will go into gear but then it dies as soon as it shifts into gear. What could be the problem? We were thinking it may be the belt is too tight and may slow the engine down so much when it goes into gear that it dies but im not real sure. Anyone have any suggestions?

 

Your probably close, but it's more likely your springs in the clutches and your buttons are bad. The clutches aren't opening up to let the belt drop down far enough to idle.

 

You might want to check the idle adjustment screw, it may be too low. Warm it up for about 5-10 mins then raise the idle a little and see if it helps.

 

you got it bro. weak spring
