I bought a 09 switchback and 1st took it out this weekend. It ran great, but when I pinched the throttle tight for a long period of time (mph about 70) it would stall or more like a rev limiter was kicking in. If I let off gas a little and went like 3/4 throttle it would be ok, as soon I pinched it tight again it would do it again. Any idea would be appreciated. I came off a 94 Vmax so not real sure how this would react.
09 Switchback rev limiter?

My 09 shift 136 did that when I first got it, took it in and there was a clutch update on the secondary the dealer did, fixed it. I think it was a duralon washer and a different helix

Ya , delrin, well the dealer called it a update and did change the helix too, don't remember the #'s, and did not charge me a dime, maybe because I buy all my sleds from him or because it was warrentee? IDK.

The information on the SLP web site now tells you that:
One delrin washer is placed between the moveable sheave and (Polaris part# 7556227 WASHER-THRUST which is also called) the 'spring cup'

Just my .02...
But I would 1st start by pulling the power-valves and make sure they are clean and functioning properly.
POO's are notorious for gumming up PV's.

Was out looking at sled today , I opened up the hood and to my surprize there was a rust color,now dried liquid splattered in front of one of the cylinders. It looks to have come out of the hole on plastic cone ( I take is power valve?) Other then holding throttle wide open for a period of time the sled ran great no pops, misses anything it ran good. That was my 1st time out with the sled since I bought I hope it doesnt end up being a nightmare! I looks to have been taking good care of very clean. I was reading on another forum and someone has mentioned clutch weights maybe wrong? Sled was registered in Idaho & WI. I could hammer it and it wouldn't miss a beat up until around 70mph.

Probably not, but he might need a new spring.

Rusty spring.... you need to get some springs & bellows & gaskets. Even if you don't need to replace them now ( except the spring ) you will need them in the future. Trust me on this one. The bellows run about $24 OEM and 17-18 AM. Always good to have some spare gaskets around also.

There could be a bad bellows in that exhaust valve, but I don't think that would cause a stall like he is talking about, a stuck valve would make it doggy and not go to top speed as normal, I would check and clean the valves, of course, but still think it is the secondary clutch, that is was what it was with mine and sounds exactly what mine did. If there is oil on the outside when you pull the cover off, there is a ripped bellows.
