ER6 Kent Cams specs: http://www.kentcams.com/product-details/1387/Camshaft/Camshaft/KAW34-Race/

Stock Versys inlet and exhaust cam lobes have less duration and lift than the 650R's... Versys inlet camshaft is however identical to 650R's exhaust camshaft.

I don't have the stock cams' base circle diameter, so I don't know what stock cam/valve lift is at.

Ninja 650R/ER6:
Inlet- open 31° BTDC................Exhaust- open 50° BBDC
close 61° ABDC........................close 30° ATDC
duration 272°..........................duration 260°
cam height 36.6 +/- 0.057 mm... cam height 35.9 +/- 0.057 mm

Versys:
Inlet- open 25° BTDC................Exhaust- open 47° BBDC
close 54° ABDC........................close 25° ATDC
duration 260°..........................duration 252°
cam height 35.9 +/- 0.057 mm... cam height 35.4 +/- 0.057 mm

ECU is also mapped differently. Versys ignition timing ranges from 10° BTDC @ 1300 rpm, to 33° BTDC @ 5000+ rpm.
ER-6: From 10° BTDC @ 1300 rpm, to 35° BTDC @ 4800+ rpm.

But isnt the point of race cams to get more lift and more duration? :) Versys is mapped differently, but i would think you could optimize it with a powercommander? Im no specialist at this, thats why i wanted to run it by you guys. :) Not shure it would work, but if it did im shure you would get a decent power upgrade. :)

Be careful what you wish for. Back when I built my Triumph dragbike, I bought a set of Harmon and Collins roller cams that were so extreme that it didn't really have ANY power till past 5,000. But once I discovered I should "dump the clutch" at 7,000... HOLY SH*T BATMAN!

I would tend to think the Ninja 650 cams would bee the better swap for a V owner looking for a bit more mid-range topend power.

The cam profiles being run by the flat track guys is a good power builder. If I ever decide to bump the performance up on my V it'll probably be done using one of their profiles. Just so happens, a buddy campaigns two of them on the GNC circut:thumb:
