I have a 06 500EFI and if I ride around for a half hour or an hour and then lift the pull rope up from the recoil I get a little rush of air that comes out. I am guessing that this is normal, probably a little pressure built up in the recoil from being cold and then warmed up. After I relieve the pressure the first time after riding for an hour it doesn't do it anymore even if I ride for another hour. Checking to see if any others with 500HO's do the same thing. Thanks.

 

I’ve never noticed that on the carbed models we’ve had. I guess pressure is better than suction, as long as it doesn’t blow the handle off and open your housing to the elements.

 

i had that happen on my o5 scrambler the other day. same thing road it around for about a half our in the cold and when i lifted thehandle off there was a little rush of air. i don't know if it's normal or not though. kind of interested myself

 

My SP 500 HO does the same thing. I never really thought anything of it but I am curious to find out what causes it and if it is a bad thing or normal.
