You might want to call Megacycle or Web. I'm sure they know.

I take it you want the numbers on a 14's cams. I measured mine the lift on the intake was .355, exhaust was .335 lift. The manual says intake is 292 degrees duration,exhaust is 278 degrees. The exhaust is quite a bit smaller compared to a zx12's exhaust cam,mainly in duration. Hope this helps. Chuck

So ??? Would the ZX14 benefit from replacing the exhaust cam with an intake?
More lift and duration? Similar to the popular Busa mod?

yep, and the trigger is on the exh cam.
not a huge deal to put a trigger on an int cam.

zx12r uses 300 degrees on intake and 292 degrees on exhaust.. why use smaller cams and throttle bodies?

Diameter of what bores, the tappet bores? Are the Valve stem centers the same distance apart. What about lift/duration and what about the retaining cap diameter. I doubt very seriously the 12R cams would be even remotely close to working.
