I did own both of the previous novarossi series engines in 3 port versions. I had an RR and an NSR. Both of these engines were hotmods. I liked the shorter stroke version better. Even though the longer stroke is supposed to have better torque, I felt they were about the same. The shorter stroke definitely was better in the mid and top end. I tried several gearings with the RR and never liked it as much. I now have a hotmod version of the N12LS3 and it is great also.
I think I am going to get a tuned version of the LL next.
