I’m a firm believer in having the shop manual for the donor bike you’re working on, and in this case I was hoping for some drawings that I could possibly use to start thinking about the motor mount. No luck on that, but I was able to get a peek at the frame with the motor removed, as well as the procedure for pulling said motor. Here’s the site that had the manual: CBRExtreme.com.
It seems kind of sketchy/unreliable, so I downloaded the manual for a ’07 and am going to post it here: 0708CBR600R
So, on page 230, you get into the motor removal section. You’ll note in the diagram above, kind of a funny thing – there appears to be a jackshaft with the final drive sprocket and it’s not altogether clear what drives this shaft. Kind of important, considering what we’re trying to do, but I’m sure it will all become clear eventually. Here’s another photo of that detail from the other side.
That appears to be the swingarm pivot shaft, and in the earlier ’05 manual it talks about removing that shaft. Can’t wait to find out how this works.
Also, this is kind of amusing. The tank, as is the wont of modern bikes, is actually a plastic thing inside of what’s a tank cover. That whole dance that we always had to do of cutting the bottom of the tank out, or making some new one? Not gonna have to happen. Kinda takes some of the sport out of the process, doesn’t it?
