I have been slowly putting my KZ1000 Superbike back together piece by piece. People been asking about frame bracing and where to put all the bracing needed to make the big KZ to handle. The frame picture here is what most people used in AMA Superbike racing from late 1977 to about 1981. All that thin plate gusseting around the steering stem is flat useless. Just remove all of it. Tubular bracing is the only answer to strengthening up the steering stem. Now if you add oversize motor mount bolts, and ream the frame and engine cases so that all the motor mount bolts are a interference fit or press fit. The motor becomes part of the frame. All other gusseting that is not shown is really not needed to strengthen up the frame.

1976 KH400 Production Road Racer.
1979 Kz1000 MK. II Old AMA/WERA Superbike.
1986 RG500G 2 stroke terror.
1986 GSXR750RG The one with the clutch that rattles!

Sorry about all the duplicates, the library in Prescott Valley just got hit by a HUGE thunder shower, then everything locked up and then went blank. Then all the duplicates popped up.
