Both sleds are boggie suspensions. Boggies were modified to ride between the drives on the track, much like a rail set up. In my series I need to stay production line chassis made before 1974. There is a loop hole in my mod class rules which will allow me to run a slide suspension. I may put a '76 gp300 suspension in that one this summer.
The 98" track is out of a Enticer 250, and the 108" (i think) is out of a Enticer 300.
My stock clutch does not seem to get too hot, but I need to work on the Secondary this summer as it shifts up too quick. The mod sled has a comet 108c primary that needs more work. havent quite found the right combo of weights and spring yet
