here they are again:

I have measured all the cams and have all the lift numbers. the contact points for the CFBs are different., the rocker arm lengths are different, the leverage ratio and pivot point is different. the valve angles are different.

are you in some race to the bottom of the stupidity pile or something?

Good luck with thumper racing. No much info from them. I sent them an email and got a reply where they told me what they want to sell to me and for how much, I then asked how to pay and where to send my cam and no answer.

Taffy started a thread, which sadly went offtopic, where cams for the 570 was brought up. From what I could get at the end of that thread is that it's more or less hopeless to get a high performance cam to the 570. Sure you could get one but unknown figures from some and generally uncertain quality. Please prove me wrong, anyone, and point me in a direction that I can trust with my cam and money. And no, I'm not a person that hold grudges, it's the result that matters.
From what I read so far on this forum, in spite of all the shit flinged at Taffy in his thread with maybe not the best reaction from him, I wouldn't question his knowledge of the 570 cam.

My plan right now is to find a competent person/firm in my area who can figure out what profile the cam should have and also who can make it. I don't want to end up like maKe sending a cam to US only to get a bad back. Was it the second or third that worked? Either it must work for sure the first time and with good results or I want to be able to talk in person during the process.
One guy has told me that a KTM 530 cam (the older version) will be better than stock 570, but I cant find no info that support that. As it looks the 570 is indeed the best from KTM. But there is room for improvement. The questions are; Who can do it? Who want to do it? Who can you trust?

I ordered one from Thumper Racing same spec as Makke's cam as the shop building my engine got a better price than I could along with a TB Bored to 45mm, CP piston etc and now the 390 airbox with the "seat mod" full Akra exhaust and ported head/Akra map should be a pretty stout engine. The 570 cam is the best from KTM I'm pretty sure so it's aftermarket to get more power.

FWIW there was this quote from Torque Monster in Oct '14 -

Web Cams in California will make you a cam for this motor - had one made for myself 3 months back.
and FWIW item #2, Web Cams are often used in DR-Z builds - and they can be built up quite far, up to 60RWHP, not uncommonly to 50RWHP out of 460-470cc - and I've never heard of a failed cam in these. Neither of a failure of a properly built and reasonably maintained valve train in these builds. (Two-piece OEM valves and tired valve springs causing failure yes, but coupled with good top-end hardware neither the cam design or implementation.)

Well you have shown us all your great and omnipotent knowledge of all things husaberg. O please I beseech thee that you may bless us with a fraction of your knowledge of which no other person on the planet possesses.

Ha ha ha, I have the cam, you don't so suck my balls, looks like I do know ya dick muncher, just stick to trolling this site and behaving like a child.
Thanks from bushmechanic

What Jon says is my opinion too.
Im quite handy around cams but for another mark so I would know what/how to ask for cam specifications, but strangely with the aftermarket guys for husaberg they will not let you know, sadly would spring to mind.

As in how could you design an engine correctly without knowing the cam profile, duration and lift?
I can only hope some cam provider reads this and deliver the proper information.

The 450 cam is a lower spec cam to 570, as its got ten degrees shorter exhaust duration and 0,5mm less lift on intakes, rest being identical.
Both cams have close to no overlap.
Thanks from berglsmerg

I have to do a valve lash check and replace my stator cover gasket. I have a dial indicator, degree wheel and half an idea. Would I be wasting my time if I tried at least to take rudimentary measurements of lift, duration at 0.050 and timing events ?
