Hey all,
I am in the middle of a build, everything stripped and undergoing machining and painting, but I have realized that I have overlooked what should have been obvious to a more experienced mechanic. But, as this is my first build and I take one step back for every step forward, I came seeking help from the sages of the internet. My situation is this; I have a 77' CB750F engine and frame that I am pairing to an 08' Yamaha R6 rear swing arm. I am fabricating the necessary frame to align the swing arm and mono-shock. However, when I checked my original chain against the R6 sprocket, it wont seat. I have read that I can drill holes in a stock cb750 rear sprocket in order to mount it to the R6 rear wheel. However, with the additional power resulting from my boring the engine to 832cc, I was hoping to keep the larger R6 rear sprocket to prevent too much torque to the rear wheel and creating a bike that is prone to rear wheel spin. Should I explore a new drive sprocket? I am kind of at a loss as to where to go from here. So, suggestions anyone? Has anyone else already come to some suitable solution? I look forward to your suggestions.
