Here is the Attex 252 Crazy Colt frame that actually started life out as a 6 chain style frame, but was converted over with some minor engineering provisions by Attex. The circled area show what parts were added or different to make the 6 chain frame into a 4 chain style. Im not 100% sure why this was done, but Im glad that this mystery has been uncovered. Now its time to get this 4 stroke conversion in gear!
