It is interesting how you mentioned in one of your posts that working on one kind of bike , in your case Honda VFR 800, makes it so familiar and over time easier to work on since you get to know little minute things about the bike and any soft spots of the vehicle. That is why I am stuck with Honda VFR 800 for a while since the platform is solid to build on. That would be really nice to have a fork swap database for sure!!! As for the 1200 engine in a car chassis I believe I have seen it someone already done it with a motorcycle engine but it definitely be interesting what YOU will come up with. Not sure if I missed it but it would be nice to know what newer rear shocks we can swap into Gen 5 that will be beneficial for the ride, I was thinking 2014 rear shock from VFR800. I have found threads with CBR and F4I shocks but they seem to be dated earliest to 2006 and feel like that would be marginal upgrade correct me if I am wrong.
