would like to get some feedback on Zippers new 110"muscle kit. my `08 ultra cvo is still basically stock, except for exhaust, breather and pwr commander, and this kit looks interesting. Zippers is again doing installs so makes it easy as I`m not far from there. am a little concerned about 10.9:1 compression. would appreciate any thoughts.

Don't know much about that kit.
The mechanical compression ratio is usually dictated by the intake closing number of a given cam, and truth be known, their combination may very well carry LESS ccp than that of the current school bus cam.

If you're going to pay for cylinders (in the Zipper's kit) it's a no-brainer (cheaper) to find some 4.060 pistons bore your cylinders and go 113".
