I just bought an Odyssey PC680 for my 91 K100RS. It arrived today and I was surprised at how much lighter and narrower it was than the Westco I had been running. I also noticed that it is slightly taller than the Westco. I have not assembled it yet as I am doing some other work, but wanted to know if anyone who has used the PC680 in a similar application had any issues with the fit of the hold down bracket, Motronic unit, etc due to the slight increase in height. Also, due to it being narrower, did you put any type of spacers in the void to keep it from moving around? Thanks...
