Does anyone know how much work there is involved in getting a mito sub frame and rear end to fit on my nc35, I love the look and can get one quite cheap.

Yes I do. I have been with Riley on several occasions when he has made them and done one for my RVF.

It is a lot more work than on an NC30, and if you need to ask, it may be better to just buy one ready made. Whilst Riley's are supplied essentially ready to bolt on, for the VFR that is, the RVF is much more involved and will require more thinking to get a proper job done.

FWIW, the silver one you missed on ebay, was mine.

Cheers, can you let me know if you come across another one please

Of course
