I bought a 1994 GSXR 750 WR, its been stood for over 10 year with original 21000 mile (engine has been ran so ok on this side) Im trying to make into streetfighter over the winter with the goal of dropping in the 1127 motor. Problem I've got is the main subframe bolts to main frame (allen head) will not free off, the heads are rounded away so will not take the 6mm allen socket. Anybody got any ideas of how to remove (before i try to drill out) Got same trouble with battery box to subframe bolts, inaccessible to get drill in, and can't remove subframe because of above?????? Going to be old school streetfighter, with a 916 style seat unit ect, ect. And finally turbo'd (but thats a long way off) Any help would be greatly appreciated,
