 40cc bzm 5 port
Hey Dazza,
if you can remember,i had a 40cc bzm 5 port w/c in that RSR that WBR Racing owns now and that blew all my competitors away and they were all on 50cc bzm and 50cc polini and zpf engines.No one could beat that bike!!!! i made a point that this 40cc bzm was unbeatable!!! i think it really boils down to A; know what your building and B;have a good race team that you and your pilots communicate together on what works and on what dosent work.i have built 40cc 3 port polini engines for instance that have pumped out over 13hp,so combinations and knowledge is crucial for a fast,strong engine. |
