flogging the proverbial dead horse......

here be the wera cb350 stocker into 350GP rules:

350 GP
Pre 1970 2 stroke twins up to 250cc.
Pre 1968 4 stroke single and twins up to 350cc.
Pre 1979 factory road racers up to 125cc.
Honda 350cc twins with the following limitations: OEM Honda twin frame and swingarm, OEM, stock, non-modified engine parts (no material removed or added), OEM carburetors (jets may be changed). The following modifications are allowed: aftermarket cam chain and cam chain tensioners, any ignition system and coils, any internal expanding drum brakes, any diameter period forks to class maximum diameter, any period exhaust system, any period body work, fairings are legal for 2006 season.

da cb350 stocker for ahrma rules be:

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!

if your running wera, don't worry about it. tech doesn't enforce "rules" they just look for safety issues on your bike. i think the whole gusseting, welding frame thing is a non-issue anyway (that is i'm all for it). if i can speak for the majority of wera cb350 riders (stocker or modified) and i think i can to a point, i'd say do it and don't look back. i know i'd never protest a win based on the guy in front of me having the backbone welded if mine wasn't. mainly cause if that was the difference in him beating me, i should hang up this roadracing thing and play chess.


p.s.- hopefully we'll meet at summit or nelson ledges this year.
