Cylinder bolt spacing is different between the NOI and the Benelli G2. It appears the Benelli is more of a rectangular shaped stud pattern and the NOI is square so that is a no go. I pulled the top end off it and noticed the exhaust port was about 30% closed up with carbon/spooge build up so I have been working on removing that. The rings were worn out and I am reading that PW50 rings are an exact match so I am going to head over to my dads and rummage through his drawer of extra rings I am sure he has some in there.
The actual exhaust outlet is super restrictive, so I might open that up a bit.
The exhaust on this thing is ridiculous ! I am hoping to fab up an exhaust using the stock header (not much material there as you can see)
Treats thinks that either a Mineralli V1 or a Morini V1 pipe could be modified to fit. Any experience with pipes on this motor?
Intakes: I took my stock Garelli NOI intake and compared it to the Benelli and they are ALMOST identical. The NOI intake would need to be slightly modified because the mounting holes are just a hair smaller.
So this intake might work:
