The issue of Novarossi is only the price. But the performance is the best Performance and its difficult for other engine companys to reproduce this high performance.

Only because Nova is to expensive I didnīt use any ...but for sure its the best engine.

The Keep On got brutal couple and amazing top speed. Nothing more to say.

Damn price

Iīam wondering why other Engine Brands didnīt go the same way of the 9 port engines with extra long stroke. Maybe isnīt so easy to do a good engine based on this features.

Only BP Racing is doing such a 9port engine.....

Others remain on the 7 port concept
