Title: KDS "RJ" cam update
Post by: Kenny on February 18, 2009, 09:00:00 AM
Okay guys, we all thought the cam was doing well even though the power dropped off a tick up top. The power "under the curve" was so good that it still made the best overall power for woods/duner builds..... Well Daniel's engine evidently broke in after some hard riding..... I don't think we will be worried about a top-end drop off.... This is very unusual to see. Thanks for the charts Daniel! :thumbs:

Had to get the specs of the build so I could figure out what's going on.
Is it +1 BOTH exhaust and intake?



QuoteKds CNC +1 valves head
Beehive springs
Kds rj cam
KDS 12.5 piston
+3 .mm kds throttle body
FCI intake no box
Dyantek programmable ignition
evac valve
Head studs w/ stock gaskets
vp110/91 50% @3500 ft elevation....
bolt together motor with the fattest power band available with a 686... nothing special....

This thing requires the beehive springs right?  Plain old KW's won't get the job done?

old kw's no......

i am recommending the beehive springs cus i know they work... anything else is all a guess

DL, with Kenny's Cam design, did you find any additional ignition timing tweaks ??

yes, it needs a bit less timing in the low end then the hc3.... but from 6 k to redline its the same


also runs near same map as a hc3... odd because it makes a ton more power bottom and mid

Daniel,

Do I need to send you my ignition for the curvs to be tweaked before my top end comes back or can I just use a different curve or what.

I'd like to see what we could do with this cam with increased spark energy and a wider gap, I bet she'll soak more fuel and push even harder  ;)
