I don't want to buy a new track now because off I think that in 1 or 2 season our local law will force us to switch to a 4 stroke ...
my doubts are about riding with an home made ported track on hard-packed snow condition (not so rare in the last few years)
anyway I think I'll go porting my track riding more carefully on hard packed snow (and making some experience for the next sled)
Tnx RJ
