How do you like your 136 or 144 extension from a 121?

Were did u find this bolt? 150 miles on 136 oft and slides are junk . Bought some excell wheels to put there

300 Miles on this set up for me, 135mm Skidoo wheels and in the position shown above.. No wear....

fac

mine was factory, but after having the 144 on the xtx, i may never buy a shorty again!
so much smoother thru the woops!
(we dont get much groomer support down here)

Is there a noticeable power loss and top end loss with either of these extensions compared to the 121? And did you have to adjust the clutching for the longer track?
