This is a newer cylinder and a newer engine that WILL beat all 2008, 2009 and 2010 engines on the track. If you put an EVO kit on this it is going to be untouchable. I don’t know maybe it’s the driver..what kind of engines do you have? Do you guys race Rotax Micro Max? You can look up the times…..my son is pretty fast. I feel bad for people that have bought big money engines that are obsolete due to not having a lettered cylinder…..good thing I have a lettered cylinder and new engines for sale.
