YZ cam doesn't seem to have this problem on the WR's.

It should be noted that my 03 WR450 was never really a good starter with the e-button even with a WR cam. (in comparision to my DRZ400) It always seemed to take several revelutions of the motor before it would fire up...but, it has always kick started well.
I opted to dump the starter, battery and other related components in the interest of saving weight. It kick starts well enough, that I don't miss the button...

I ordered a set of Yamaha YZ cams and the sucker fired right up.
I'm a ASE certified Master Mechanic and from what I can see the Hotcam decompression pin is way too short. Less than half the length of the stock wr or yz camshafts. It would barely touch the valve bucket. The stock cam pushed the bucket down considerably.
I can't see how they expect it to let enough compression off to allow that wimpy starter to turn it over. I even thought about taking the stock pin out of my old wr cam, but opted to just buy the stock yz cams. Worked much better and a whole lot less agravation dealing with the hotcam no start issue. Maybe they'll figure out there is a problem.

I ended up buying a set of OEM YZ cams on thumpertalk OEM store.
Fires right up with the electric start. I'm not for sure what the duration and lift difference is with the WR verses the YZ camshafts, but runs really good.
I'd say until Hotcams gets this figured out, don't waste the money for them.
I also had the 4401-1E camshaft. They way I look at it, Hotcams Dropped the ball on me. If they can send me a camshaft that will work with my electric starter and I'll gladly put it in. As it is they cost me about $300 which is what I was out screwing with their cams. And still ended up having to buy OEM cams for $200. Not good customer service in my opinion.
