Hey Das...
I've been doing a lot of research on the "baffling" of 2stroke gas motors... It's amazing the change in engine performance when cooling is done correctly... on our TF GS FW190 the stock faux fan blade mounted on the inside of the cowl desperately needs to be modified to pass air directly over the cylinder head. It doesn't have to be a big gaping inlet... The idea is to have cool air enter and move over the cylinder(s) and have 2 to 3 times the exit (inlet vs exhaust ratio).
The pros over at RCSB build structure over the entire cylinder while being careful to not agitate the airflow (smooth curves, no sharp edges, etc)... The effect of having cool air right over the cylinders improves engine performance and longevity...
I've just finished the one for the Meister Wulf and I'll have pics up shortly... let me know what you think...
