The sled is already a 151. He put Rx1 rails on the original skid. But the track on there is pretty rough, thats why I was inquiring about putting a 16" one on. So the sled is already set up gearing and hopefully clutching wise for that track. But I will still have to play around with it if I want to run it here at home, Its set up for the mountains now.
I do have the srx for running here at home but I'm sure I'll be too curious and want to try the viper out here sometime too. This viper has bender pipes on it so I'm hoping that my 141" srx clutching might be close so I have a baseline to start at. I've got 8bu-00's in it with a hauck G helix and I love the way it pulls all the way to 100 mph. Has anybody ever tried these weights in a piped viper? I know the two sleds run at different desired rpm ranges but I dont know how that will effect what weights will work for the clutching. I was thinking about pulling my srx primary and secondary and trying them on the viper and see what happens. (after I regear it too)
Thanks Ding, I'll check and see what rivets I might have to grind down. And the Button head bolts for the chaincase sound like a good idea. I'll try that since I'll be pulling the chaincase anyways to change out the track.
