I was wondering the other day if anyone was still running these motors or not, just seems like you don't hear much at all about them anymore, 250's, 450's etc. seem to be the hot ticket anymore in unlimiteds.......


They were phased out by the rules. They can be competitive on smaller tracks. But big tracks, they just don't have the power to run with something like a 450, jawa, or 275 2-stroke. EFI helped bring ours up to speed, but the cost is hard to justify when you could spend less on a jawa or 450 and have 20 more hp. Still the best karting specific engine ever, imo.
