This is Biggpappabear2 and I have a kz650 and got the last big bore kit form the 80’s. That will make it 830 cc but I can go to 880 and maybe 900cc with titanium pistons and beryllium rods and maybe beryllium pistons with roller crank and cams and transmission bearings. Add twin turbos and watch out.

Ted, Where did you get your fender eliminator fabricated? Between the fitting diagram and the final product in your last picture boggles my mind. It is absolutely beautiful and you didn’t have to cut the frame.

@Joe the larger cams aren’t necessary. On my cams you don’t really notice the power until you are above 6k rpms.

I have no idea when anyone last replied on this but I’m looking to install the larger pistons, is it essential the cam needs to be changed to do this ? And can the larger pistons be installed onto a standard z 650 Con rod ? Thanks

@Adam @Ed @ Pat @Alex
Thanks guys. I need to find more time to work on it. Seems to be the major hurdle right now. I will keep dig at it slowly and surely.

Thanks. I reached out to Andrews and they actually dug around some old catalogs and sent me a scan PDF of the cams they used to sell. Here’s the link.

To mount the oil cooler I thought about two options. First option, build a bracket that attaches to holes where the horn is mounted. Second option, move the tabs on the cooler to fit in the holes where the horn is. The cooler is aluminum so I am not sure if welding those tabs on and off is a good idea.

Looks awesome Ted. Jealous that you had cams in there already. Did you find any more specs on that cam profile?

I also swapped to the GPZ oil pan to the run the oil cooler. How do you plan on mounting the cooler?
