Stage 2 Hot Cam
 

I now have a Stage 2 Hot Cam to add to my list of mods.

I quite like this cam it pulls really hard up top, I should have used this cam on my previous Raptor 700 conversion. I have spent most of today building the fuel map.

Is that your bike Kev? (with O2 sensor?)

Great photos...I bet it pulls like a train!! Is it a high lift/short duration cam?

It is a wide band O2 sensor for my Wide Band Commander.

Intake Intake lift (mm): 10.30
Intake lobe center (degrees): 111.00
Intake duration (degrees at 1mm): 260.00
Intake valve lash (mm): 0.10

Exhaust Exhaust lift (mm): 8.60
Exhaust lobe center (degrees): 102.50
Exhaust duration (degrees at 1mm): 243.00
Exhaust valve lash (mm): 0.18

I realise that you have only just done this, and haven't used it much, but where roughly does the power "kick in" Kev? Are you using the recommended cam timing?
Have you noticed a drop in pull/power in the lower revs, ?
I need more feedback!!lol!!

down boy, down!

Below 5000rpm less power but very smooth, above 5500rpm to rev limiter power all the way. I hit the rev limiter in 2nd & 3rd without realizing it is reving that high. It revs very easily now. If you do not ride your bike hard this cam is not for you.

I will get it on the dyno for a run, then advance the cam 4 degrees then do a compassion run.

The stage 1 hot cam gave me 6.76 extra HP at 7000rpm over a the standard XT660X cam tested on the dyno, so I would expect an extra 2 to 3 more HP over the stage 1 at 7000rpm. A possible 8.5HP gain at 7000rpm.

:gobain:.......i can wait (for another 10 seconds!)

Very nice!

Looks like these cams are fairly easy to change?

Are they worth the initial outlay though?

Very easy to change took me an hour.

Depends on how you ride, if you can't build your own fuel maps the cost goes up, ie dyno tune.

Also the Hot Cam is not a complete swap over, you need the Raptor 700 decompressioner & sprocket, bought seperatly.
