It will probably fit the frame, but the seat, and ignition might be an issue.
I have an 888 tank in the shop if you need some numbers.
thanks for the response
for the seat I would go for something like this :

there was a pic' a while back somewhere here on the forum of an old monster with a 851/888 tank
it may have been some prototype, not sure what was involved
I haven't been able to find the pic now, don't remember the thread
I was initially considering a 999 tank but doing the research it requires quite a bit of frame modding
