I have a handful of the new Novarossi N21R 3 port engines that are new in the factory sealed box. I am offering them for $135 shipped in the lower 48. Thanks!

so this is a N21Bf with a new case and head? any of the specs change?

PowerHouse · 11-07-2009, 03:10 AM

This is the N21BF Limited with a new head. It has the 14mm crank, 25.4mm rear bearing and the newer case like the N21BF. The internal layout and timing specs remain the same. I still have a bunch available. Thanks

did the 14mm crank change the powerband or performance

PowerHouse · 11-12-2009, 02:11 PM

By increasing the diameter of the crank, it allowed the ability to advance the crank intake timing without sacraficing the stength of the shaft. The new 14mm crank with the same factory depth cut gave the crank a 10 degree advancement in induction timing as well so the engine does run better with the new crank. My race ported version runs side by side with my race ported P5 and Plus21-4 and I have those available for $175 for a limited time offer. I also still have the stock ones available for $135.

Does the ported version come with a bearing upgrade?
