More or less yes you can.... Novarossi are extremely conservative and leave plenty of room to to remove shims.... this is why a OS Speed seems soo powerful..OS doesn't mess about and runs their heads 0.2 mm closer to the piston then Novarossi does... which can add up to a huge power increase

does anyone know if nova built another square stroke motor with a 14mm crank other than the 3cq/nv21b?

Ielasi tuned and the older RB WS series

Like the ws7III? I thought those were 13mm cranks

Yes, you are right... 13mm... (not sure about the WS7-III)

I Guys, I just bought a brand new Nova VirTus 21/S Off with double ceramic bearings.
Which recommended muffler for medium-long circuits?
Thanks

41021/2096, 41032/9886

Picked up a Legend 7, 41031 manifold, and 51016 (9901) pipe. Anyone have experience with this engine? I'm putting it in a buggy.

Thanks
 

What about a OS Speed 2060 or Alpha Plus 2107 ?

Legend 7 is very smooth, good combo with the pipe but i never like it, prefer 2096 n 9886 only for nova pipe line up

Will this bearing work as a replacement for a Mito4 or is the Nova bearing the only option?

Nope, no direct fit due the smaller inner ring. You are stuck with the most expensive bearing there is.....

I have modified a crankcase once to fit a normal bearing:

Well that sucks,lol

Does the Hudy tool work to remove this bearing?

Yes, tko has the bearing, same as keep off bearing

The mito have a 14.5mm crank like the keep off 7 and virtus. Noone else makes that bearing cheapest I have found for a replacement ceramic for it is about 70us
