Any particular reason for your choice of belt? If you said other, specify the brand.

I've tried Dayco, but it just didn't perform the way I liked. I use the SkiDoo 067 belt now.

I forgot to include them in the poll, but is Goodyear still making the Power Streak belt?

i gave my vote to OEM. We run the 127's . They will easily last 2000 kliks if you break it in and follow proper startup procedures. The 067's take 5mph off of top end. I put a dayco 144-4353 on the GADE when i was in cochrane last. It held up well to a 1000 kliks of powder busting

I run OEM in my sleds.  The OEM belt just seems to make the sled go faster and accel harder.  

I used Goodyear Powerstreak and I was impressed buy how it held up.  It lasted over 1 and 1/2 seasons till it was warn but it never broke.  

The only problem was that the good year didnt perform. I would get it for a touring machine but not for a racer.

Dayco is also good but OEM just seems better.

Dayco

Been good to me.  Never compared directly to an OEM belt as for a speed loss.  Might have to give that a try.

The Dayco I had seemed to slip more and the clutches would run hotter...too hot...snow vaporized if it touched the primary...forget putting your hand on it!

I've just switched back to oem bomb. (067) belt, and it seems to be holding up well and not wearing out too quickly.
For the last few seasons, I used Dayco ultimax II's, the 138-4353 and then the 144-4353. I liked those belts for racing, but they wore out quickly (belt got narrow), and some of them would have cord pull out. I also noticed that when switching from dayco to bomb., I had to either click up tra one or remove 1-1.5g of pin weight to keep rpms.

Does anyone know if Dayco makes the Bombi belts? looking at the markings on the belts, they do look similiar. I would assume though that Ski-doo would have specs as to the tolerances and rubber compounds that they would what the belts made to.

permafrost...I've been thinking about this for a while...and I can't figure out how the 067 Doo belt can take 5 mph off your sled? Please enlighten me.

I'm not sure of the PNs, but I have read in Ski-doo's info that one belt is better for top speed and the other is better for wear. now if I could only find it in my junque.

While I stay OEM, I still tinker with belt performance by changing my helix on the driven clutch to a 51 from a 55 for more positive shifting for my riding style.  Slow, in deep deep powder through the trees.

I normally run an oem Bombardier belt but right now have on a Dayco Ultimax.  It works excellent!
