Smallframe Cowl Modification

I’m planning a cowl modification for my special/pv bastard, and my question is: Do i need to reinforce the body if i cut of the cowl’s on both sides of the body…? The cowls are going on again but with welded hinges like the ones you got on largeframe body’s, you may ask why i’m doing this, the answer is: easy axcess to both engine, exhaust, wheel, and a bit more space for some engine modding… I remember i saw a german smallframe with this mod, but i can’t find anyone else, and thereby have no references…

Any help would be appreciated…
