Hey all. I’m curious about the differences between the above mentioned. I want to know what are the similarities and differences and if I can swap parts directly across the engines. As I understand, they are the same architecture, but the V85tt has more displacement, titanium rods, and different cams and pushrods. Everything else, I’m not sure of (rocker ratio, valve sizes, head size, etc).

Anyone can chime in if a swap of individual parts, or even a whole engine swap, are a possible backyard project?
 
I doubt you’ll find anyone that has done this (yet), as the biggest challenge would be sorting the fueling, and you simply won’t get the same power because of the smaller throttle body. The other is that the cam sensor is massively different, as may be a few other sensors. It won’t be a simple swap. I’d be willing to try and tackle it if you’re willing to invest the time and $. If so, ping me via email; Info @GuzziTech.com

Best is to do our 820cc kit below.

 
And if you change the whole engine... you start with cutting off the V85 engine mounting bosses on the engine block first.... you are committed after that...😂

Are there that many differences? Dang that stinks. I’ll PM anyway just because you got me curious now.
