Ah ok, well thanks for the info. Im more talking about the tunnel extension as thats not changing. I was never going for rail extensions. I was just wondering if moving back works? If not Id put a 136 in it.

Course I haven't completely decided if I want to put a 136 on it. Might just look for a different 121 track.
I don't do much trail riding. Id take it off when I do. Just for looks. I do more riding on private property. In fields and a valley by my house.
I plan to put it in the garage soon and tearing it down and rebuilding it. Its losing coolant someplace, most likely the pump among other things that need to be gone over, checked, replaced. So I decided to just rebuild it.
Again thanks for the info. This site has been very helpful. I don't mind personal opinions from fellow riders. Opinions can help. I dont like them from the group thats never been on a sled and knocks them.
I really should have done all the work to it when it was in storage for 4-5 years thanks to no snow in my area. Ah well. I'll get it done. If I can find a good skid for it depending on what I decide for sure to do.
