I purchased a 2019 skidoo G4 600R 154 last year and absolutely love this this sled it is a blast to ride and just so fun. I was thinking of taking it and making it a 165 2.5 track. Couple questions to do this im thinking I would just need to get rails, hifax, and new skidoo gen $ 2.5 track everything else would just swap over. Am I missing anything here? Also im wondering if this would take away from the fun of the little 600. I know you can buy the 154 in a 3inch track so I was thinking power shouldnt be a problem for a 165 2.5 track. I know buying a 850 is the easy way to go but im just getting older and dont really need all that power of 850 I just sold my 18 175 850 as it was a crazy go anywhere sled. Any thoughts on this would be great. Thanks
