99 Thundercat with race ported cyclinder and heads. Bored carbs,Delta reeds, Kick ### air cleaners on it now, but stock air box with D&D power breather included. New clutch, new camoplast track 2years ago. New 192 1 5/16 studs. This machine was originally set up for grass dragging, and the combo was to give 220 to 230 hp. I tamed it slightly to trail ride it. It does'nt have the advace keyway in it and I had the race fuel heads swapped for requler gas heads. These heads were cut by speedwerx and I have'nt noticed a difference in performance. This sled pulls to 9200 and is wicked fast. I hadthe skis off theground to 75mph. This machine also has reverse which I just added this year. Imasking $3500 obo and the machine is also listed on ebay. item#280087254549.
