Rail/tunnel extension

I'm riding a 91 indy trail and I'm putting a rail/tunnel extension on it for this winter. . Want to put tallest track lugs under it I can with no binding or rubbing issues. . I believe I can put a 1inch lug track under it but not sure and hope it will take up to 1 1/4. . If anyone can let me know for sure what I can run I would appreciate some words from the wise. . Thanks to any and all who answer

long tracks in my opinion are a waste of money. get a deeper lugged track. extensions do improve traction but are very expensive, anddont increase the value much. especially with it being a 91. if your looking for even more stud the track too.

^ I have 300 in my long track kit for the gf's Indy 500 and everything is new but track. They ride a lot better as there longer and go over the whoops and bumps instead of following them. And you can't go very big lug on these old Indys especially with studs.


I think you can run 1 1/4 with no studs but it might rub cooler. I run a 1" with studs and it is close.

Cool thats what I was hoping. I have just a 3/8 inch lug track right now and plan on putting a 1inch paddle and a 136 extension kit on. After I put a new top end in (4800 miles) things should be just right. .
Thanks

You don't need deep powder to run a 136 or any length track. Depends on the lug height that will make or break a nice day of rising. I ran my 151 with a 1 1/4 track on trails for a year and loved how nice it rode. I personally like them for the better ride quality. And also than you got some tunnel space for a gas can or storage bag!

Your machine has no coolers so you can probably run up to a 1 1/2" paddle. Might have to drop a hole of two on front suspension mount for clearance inside tunnel

It should still have the tunnel strips on the top of the tunnel.

Hmm...all the fan cooled sleds I worked on at the dealer had tunnel strips from what I remember. Must of been added. I know all the tx and txc sleds had tunnel strips and those are free air sleds

Def no tunnel guards on my 91, pulled the skid off it today. . Super simple after reading through a couple forums on here. Love this site!
I am dropped to the lower hole on the front of t he skid and have drop mounts on the back, so I imagine a 1 1/2" paddle will fit. . Pretty stoked to get my new kit on! It will be a while before I do it but will post some pics when I get it all done.. Thanks everyone
