After the tech seminar at GoPro Motorplex today for the RMax classes, I was struck by the amount of little details policed and required for spec, sealed racing. Not unreasonable, and neccesary to keep things close, but tedious sometimes.
Which led me to wonder….who’s played with their Rotax to make it a bit more powerful and easier to tune / more similar to pre-existing kart engines. Off the top of my head:
– Smaller, and tilly style carb
– Vevey-style pipe or ICC pipe
– Porting mods
– Head and dome mods
– retrofitting a tunable clutch
Just curious what’s been done and what people’s experiences were… I don’t know that the MAX in Rotax is an apt name, but I do admire the stability of the platform and longevity of the engine. Obviously mods would shorten that, but I bet it’s be a different beast to drive too….
Walt, I’m not saying it’s “ideal”, I was just curious… I race unlimited dirt oval, so you see all kinds of oddball combos…and modifications. This Rotax may become a mod for my dirt kart if I get good info here, or I’ll update it to current RMax specs. I was simply curious. :)
