It's a rivet that hangs lower than the cooling fins of the heat exchanger close to the drive shaft. It's in the centre of the tunnel.

I rode an xm this weekend with a 162x16x3(old style) camo and it felt identical to my 163 only had way more pull right off the get go in the tress and in the deep stuff at the top of a few good hills we could find where mine would quickly trench out once we left all the tracks from others attemps. I am definately going that direction. Just my 2 cents tho!

Once you go 3" you can't go back! Already have an old style camo 3 in the shop waiting!

Better than stock is a relative term lol. if were talking about starting off on an incline or in deep deep powder or travelling at slower speeds in tight areas then absolutely its better than stock. it IS going to be a little slower and not want to carve as well as the stock track but IMO thats an ok trade off for me because of the way/places I like to ride.

General did you gear up or leave it geared down abit with the small driver? I hear some guys gearing as low as 2.60 with good results?

Did he have drop and roll or smaller drivers?

 

[MoThEr TrUcKeR]

7 tooth drivers. Which I am doing also.

Thanks I have ol 162 3" in shop off my 1000 was getting seat time before swap. Did your buddy gear up or leave it 19 t?

 

[MoThEr TrUcKeR]

Left the 19 and dropped some pin weight. I'm not sure if ill be doing that I'd like to keep the pin weight and go for a different primary spring or something. The drivers add up to about 13% reduction so iv been told so with stock gearing and clutching I figure that driver change should almost have the track change compensated. Just my thoughts tho.

 

[MoThEr TrUcKeR]

I'm not even sure if its possible to gear down more?? I don't think you'd wanna do an 18 top gear if they make it and I don't think a bigger bottom gear would fit. Haven't looked into it that much just yet tho so don't hold me to it!

 

[maxwell]

had an 18 on another sled it was HARD on chains.

I like lighter pins also as engine responds quicker to throttle changes. Yes stock gearing should be good also although some are going to 21 tooth. I think brp has to much weight on pins on just about all sleds.

 

[MoThEr TrUcKeR]

Ya mine had fully loaded pins. And I'm runnin a 20 top so ill be doin less weight and 19 top

I can imagine! that's quite a small radius to bend around at that velocity. 19's bad enough

 

[Caper11]

Fully loaded pins??? Not from the factory. It's only 14.5g from the factory lots of room left for more setscrews. I geared to 21/51 on my 2011, but was running clutching that worked with it. The stock gearing with the 7t bring a spare chain.

Ill do some more testing this weekend but I'm leaning this way Aswell. Track is just to heavy. If you could add 10hp and get it spinning a little faster it would be a different story
