I really wish there was KPV/HPV/support at my local track. The performance level, the cost effectiveness of running that simple and durable engine was hard to beat.
I’ll be doing a few select Rotax Races in 2015 as that is the engine supported my my local track and thus the engine that has the most participants. That said, I read TJ’s article and it is spot on. I’d switch to a air-coolled 100cc program in a heart-beat if there was support/participate.
