Hi Guys, creating a separate thread to answer this question. While I have my "Clean" VF1000R and my Euro Project VF1000R, both with factory correct engines. I have another Frame and enough parts to build a 3rd bike (once im done the Euro). However, what I dont have is a 3rd engine. If I find a 3rd engine, of course that solves my issue for that 3rd bike build, however these bikes are not plentiful here in Canada (despite the fact that i found 4 of them 2 weeks ago). So....what other engines wil fit in a VF1000R frame (with some minor mods). I believe a VF750F engine, possibly a VF1000F ? If these will fit, or others, Ill build a Custom "VF750R" maybe in rothmans livery to go with my VF500R. what say the experts, what are my easiest options ??
