08 cam spec

'06 628cc cam marked 820-08. 5/2522

Can anyone give me the spec for this cam? We're looking for valve lift, timing etc. Need as much info as possible to match gas flow with oversize valves.

Many thanks

Valve open/close data

.

actual 40 thou duration with lash at zero is 266 deg both lobes, lift measured 10.6mm


in open 19 in close 67.1 ex open 68.8 ex close 17.9 cls 114 and 115and a bit

obviously it is "supposed" to be symmetrical with open close figures identical for intake and exhaust which they will be if you aim for the cls being identical and around 114.6

the 08 cam is very very good high peak torque and high peak power but the delivery is lumpy, if you want smooth try a different cam ive tried many cams and with the 8/07 discontinued I would now use the thumperacing rfs stage 4

The part number for the 8/07 is SMS36010000.

You have to cut the KTM water pump shaft of the end.

ta spanner apparently the 8/07 and 8/33 are discontinued parts

webcams have RFS billet cams and so do thumper racing there are others but those 2 have the widest choice.

FWIW the stock 08 cam is very very good for peak tourque and peak power at reasonable compression ratios despite its relatively "lame" specs

My man thought the 08 cam looked ' a bit tame' but I said it gets a good right up, I've printed off the cam file and I'll post it down to him, he's 50 odd miles away so I can't just drop it in. Ideally he wanted to build the motor from the crank up, something he does for the MX boys but they're sponsored and I've got a house and a women to keep!p
