Good to see another one being used for hills, great little cars..
Mine isnt a busa motor, its a gsxr1100 (1370cc BB conversion) so Im not sure what the diff in gear ratios are, but if any use I run a 15/48 on 21" rubber.
I can e-mail you an excel spreadsheet if you like - it lacks a bit but if you need it just e-mail me tanky%srgsy.co.uk (change % for @).
If anone has a better one for a gsxr 1100 i'll take a copy too
regards
