Compression is probably low

I’m curious what others have figured out works best for the 850. I like Dalton products and always had great luck in their components but I was able to get the SLP magnums to perform a bit better for drag racing. I’m curious how Belly Busters work, I see they have a few styles. Their standard...

“We have rented Indy 550's several times but they are two stroke and pull start.” All modern Polaris snowmobiles are 2 strokes plus 2 strokes are a lot lighter and much better off trail. You can get electric start with a 550.

What fuel mode do you have it in?

Order it directly from Gboost. OEM belts are more expensive

There’s been a couple people on another forum say theirs broke.

Damn, I live in New Brunswick Canada. Too far for me but when you get the cables I’ll be interested

what gains are you seeing with the tune? Does the customer need to send the ECU to you for it?

I haven’t ran against other sleds yet. Mine is a 137” VR1 850 with 1.5 Storm track. My new one definitely pulls better than my 129” 850. It launches way better.

I agree, it’s better to wait and make sure your setup is good to go especially when it’s custom parts.

Oil is a hot topic normally. I sell Amsoil at my shop and truly believe in their products however I’m not afraid to try other oils too. I’ve heard lots of good stuff about Ipone oil, Mystik, Klotz, and other brands. Pick one and go for it.

Itek industries makes them with rubber idlers for trail riding

My 850 is around 75-80•

I just googled it because I was curious too, it’s a Bluetooth helmet headset.

For $7500, do you get the sled with the Can? Lol

Could also be dirty/faulty fuel injector.

Could be the fuel filter or the belt deflection could be off (belt riding too high in secondary)

It could be a voltage regulator, similar symptoms on my IQ 700 and it was because of a faulty voltage regulator.
