you could get the critical parts you need anyways enough to get it running and rolling then ride it, see how it rides, definitely inspect that frame real good everywhere which means a total strip down, it may have a stress crack where its not visible complete, I might have it x rayed if I am riding it, the chips may be a sign of bends?
remove that tank and bodywork is that a crack along the frame behind the chip out? would give cause that frame bent on impact, I just cannot tell if its a crack there or a scratch?
how does the shape look? have anything to compare it to that's known straight? that big dimple ahead of the crack always there..
a straight frame maybe in order, almost as much to put on jig, measure then straighten as a good used.. all the rest is common parts should be everywhere and accessible, some cheap, some not so for what it is, $400-$500 prolly get the entire front clip minus wheels and brakes, forks, triple tree, clip ons? $150 radiator, $150 headlight and brackets.. $150 stator case, hard to tell what all fasteernsadbodywork is needed, they have chynese kits for $500 shipped.. or piece it together and wait for color matched pieces to show up... still waiting after 6 years for a color matched busa nose to appear..
