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 **** 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 **** muncher, just stick to trolling this site and behaving like a child.

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.

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 ?
 
Ok I must warn you to not hold your breath, my rostered week at work begins tomorrow, will try to do bits and pieces when I can.
 
nice one bergsmlerg if you provide the measured specs and engine specs and application in a question on SpeedTalk you will get some seriously knowledgeable responses and no doubt end up with something web cams already makes.

eg Cam profile, Any suggestions? ? Speed Talk

currently all you have is self promotional bumblings from the site Troll who's claim to cam profile design is that he copied someone elses 10 year old profiles, had them made out of cheese and gave them different names.
 
No action yet, 14 hour days after the hour bus ride each way. Work close to home they said, home every night they said.

I've lurked around speed talk but the knowledge pool the is formidable and I'd just be a pothole in the information highway. But if I went with some solid numbers....
 
yes i know what you mean mate

tom toms perfectly linear Swedish diplomacy and experience would fit in smoothly on speed talk
 
The cams I have from left to right ---- stock : pretty wild : very crazy

The one on the far right is as big of lobe as you can fit and required just a bit of work to the rocker shaft to get it clearance. Middle cam did not require any mods to fit.

I do not have specs on the cams but they do work.

To get a cam done for these motors you must start with a stock cam and then they are hard welded and reground to new specs.



I might part with the cam in the middle, I got it used and it is not pretty but it works. I do not need three cams.

Yeah, what are the chances of me posting during my annual five minutes of mental stability... :D

Edit: Thinking about this again...I called webcams and they can produce pretty much any cam profile you desire from an oem core.
I have half an idea what cam would be good in there timing and lift wise.
What makes things a tad diffo is that they do not have a head to measure the cam in so any directions/specs needs to be translated to directly on the cam.
I could try Jens at former husaberg and see if he has the rocker arm ratio still, if so this could work.
Another option of getting info may have opened up today as I did some dyno stuff for a guy quite involved in KTM.

I will soon disassemble my motard and if you have a good plan for a cam profile we could send my head and our cams to them.

Torque Monster, that "very crazy cam" looks indeed very crazy!

A bit of work yes, but plausible.
Manage this and we have a profile that we know and will be free for anyone around, as in exactly what were looking for.

Lke the idea here.

Jon, will it be ok for you to this later this season? Like late july?
Cramped up badly now but by then much better and Ill have the energy to make the calls necessary.
If its head off on, I can make myself prioritise that too, rather the first option if possible? Much smoother to me.

Just fine by me. Plenty of projects in my life and and that bike is sadly quite down the list right now. But whenever the head needs to go off I can do it in no time.
 
First time I've done this so if it sounds off let me know. Measurement taken at valve spring retainer, lift numbers I don't trust as it's impossible to get a straight shot at the retainer.

Intake lash .005
Lift .388
Duration @.050 250d
Ivo 23d
Ivc 60d
Peak lift 140d

Exhaust lash .006
Lift .421
Duration @ .050 234d
Evo 113d
Evc 44d
