da cb350 stocker for ahrma rules be:
10.6 NOVICE HISTORIC PRODUCTION
Novice Historic Production is open to production street machines built up to December 31, 1972, and like design. Machines must use the standard production OEM frame, swingarm, forks and handlebar mounts. Engines must be original OEM bore and stroke regardless of displacement (plus allowable overbore, as described in rule 9.7). Classes are Lightweight (four-strokes up to 500cc, 250cc two-strokes and certain 350cc two-strokes) and Heavyweight (four-strokes up to 750cc and 350-500cc two-strokes).
so my question is, if you crack your frame, can you weld it? or do you have to take all the stuff off it and replace it with a new, oem, stock frame?
this is beginning to get re-god-damn-diculous!
