Any news on 570 cams?

Your bike gets max power at 9200/9300 rpm mine around 8600.
What else was changed with my custom map rev limiter is set at 10400rpm (If I remember correctly it's a 450 map) but the bike will never pull to that kind of rpm.
I think even 9000 rpm in my case is very rare peter advised his custom TB that would mak a huge improvement on topend and the revs/hp would be up another 1000 rpm+-7 hp he claims but I would loose on lower rpm even more...
Make who used to be on this forum had this TB setup with stock head and stock ecu/stock cam just carrilo high comp piston and full ex system/dna filter and got to 69 on the wheel...
A shame that I can't contact him anymore...

I just did the heads and mounted the piston, then proper fuel mapping in the dyno. Just did the heads makes it sound quick, it wasnt, had the bike apart for a year actually and visited the heads like 20 times.

I had in mind to change the throttle to a bigger one, but its not reversible as you need to file the head to fit, so I figured Id try stock before anything, Im a tight coward, or wise, pick a choose as Im not sure either haha!
All I know is I will go back and try, but right now its racing time and I wont touch anything.
Bike is deceivingly quick as is, you wont notice while riding but theyre gone sorta thing, good for racing yes.

My bike isn't even mapped on dyno maybe there are still some small gains in it with proper mapping but do'nt expect to get 2 more horspeower just because of that:p
Now it is being rebuild still using all stock parts just a carillo rod and 5grams lighter wossner piston pin +0.001 hp:cool::p
Maybe with new piston/rings slightly more compression I will make it to 64:ninja:
But 300€ for getting it mapped is a lot of money IMO:rolleyes:
 
300? Im not the tight one I realise :)
I can get my map from my tight arse piggy and send you, its not too far off the oem.
Higher comp makes it richer with the same map, awkward but a fact.
I think 70 SAE corrected whp is in the cards from 565cc yes (if oem is at 52), Ill dig into that in april when racing is over, or in december with a torch up my **** :)

Hello tom, yes clakity clak goes the top end, there was never any mention about valve springs so I just checked for coil bind, PTV clearance and retainer to valve guide clearance. It sort of reminds me of a v8 car I had with a solid tappet cam, except I probably wont have to adjust valves every 1500km.
I guess I have a fairly radical profile with no quieting ramps just get that valve open, quick!

Would like to dyno mine but the cost is prohibitive, then again I have a big sand dyno and some 450 mxers to beat up on.

Funny you should say that, darn the cylinders had no scuffing and the underside of the piston looked brand new after 150 hours, never seen that on an 'mx engine' until now. Its a design that never got a price for what it is!
I declared my intentions for jens at husaberg and he said you can do whatever you want to it, it wont break. It will be two kilograms heavier but it will last like nothing else. Im ready to take his word.

f..k yeah!

Say hi from husaberg.org and thanks to the man if you get the chance - there are people out here that realize what they built!

Tom, I bought all the JBS replaceable lobe cam stock he got rid of (aswell as most of the other stuff) im being a BIG tease here as A:im not sure if they fit the 570, B: Im still yet to even open the package, C: im away with business and don't have a exit date.

so if and when I finally get home (im in london at the moment, in hotel but I work in conflict areas, mostly west africa leaving for sierra leone on weds!) I could put together a set of them for you and send them over (for a fair price) I have about 6 sets of these JBS replacable lobe cam kits in total.

and a few spares of other JBS parts too (oil cooler mod, oil cooler etc to name just 2)

I also bought the blue prints for some of the JBS parts, which im not too fussed on making anything on them just secured them so we can all benefit (if and when I ever get home) and ultimately I can make my flat tracker faster/more awesome

JBS Racing Replaceable-Lobe Camshaft

A camshaft like no other, both the exhaust and inlet lobes bolt onto a hardened and ground high-tensile steel carrier. They are retained by a keyway and clamped in place by an M16x1.00mm nut (same size as the crank). Each lobe is individually adjustable so the overlap and cam timing can be closely controlled. New lobes can be supplied for far less than the cost of an OEM camshaft and lobes can be miss-matched so that different profiles of inlet and exhaust can be tried together for optimum results for your unique application of the Husaberg engine. This cam fits all models of Husaberg and we can modify it to fit KTM’s.

I like the idea but I guess they will not fit a 570..? They do not look like a too easy fit even if one were to machine them, and no auto-decompressor.

the old previous Husaberg cams can't go anywhere near the 2009-2012 models. they are made completely differently. the list is endless of the reasons why.

anyway, i now have same more race cams/R & T for the older generation from my new supplier. I will see how they go first before I even think about a cam for the 570.

your best bet is still to nik one out of a high performance KTM if they (ever) do one.

Just found a local dealer for the Grossewächter tornado cam, supposedly Ill get the timing info for it.
And poked thumper racing again...

You will NEVER get numbers from Thumper. I owned one of his cams and he would not give me the numbers for it. I never got around to getting the numbers the hard way myself. Berglsmerg has it now.

Thats really unfortunate, for them, I wont buy it unless I get the info. If theyre scared someones gonna nick it, they will anyways, just buy it and put it in a cam doctor thingy and call web cams then press order. If I were them Id advertise the data to attract customers, but thats just me.
I gladly share specific cam timing and stuff like that on a build, as when I do it it will take another person at least a year to replicate it, and by then Im a mile ahead. Be clear Im not a berg tuner, but info is treated the same for any motor.

Whats worth a million is combinations on a certain engine that works, a cam isolated wont do this, sorry to rant, still think its backwards thinking not revealing such basic stuff so the builder can evaluate their product. Again very unusual in the tuning industry as whole, dont have to say Im unimpressed, do I?

Webcams have spun the oem cam, and will do custom cams for very reasonable doe, if it isnt the exact specs of the TR I can have a copy, see how simple it is to go around it. Now I have no intention of copying theirs, I have my own numbers dont worry.
A 255/255 cam at 1mm lift, centerline 113/107, Id like to have for my engine, PLEASE :D

Small update, more in the fashion of a dead end. Spoke to Mr J at berg about cams and learned that any KTM 450 single cam head fits (identical) on the 570 70 degree engine, this may be old news, Im just regurgitating anyways, credit due to the old berg crew. Subsequently if you mount such a head its also possible to use those cams (duuh :)), and the SM 450 cam is the best looking at 248/242 10,5mm/9mm 108/108, not an improvement to a 570 OEM cammed open course intended engine Im afraid, at least not worth the effort and doe.
You got to applaud customer service here, Jens just shouts to the tech, what cam numbers for xxx? And hes got them in his head, this I like!

The 450 single cam head is different to the 70 degree head in that it uses a follower instead of a rocker to cope better with revs. From that the lobe with is different and will interfere with the 570 head.

Upside is the SX cam in the single cam 450 head is the exact specs as the 570 plus identical valves and combustion chamber, meaning its a direct replacement in appearance and performance for your recently valve-salladed 570 head :cold: :D

Interesting stuff I let you guys be the ones to test these things and post dyno sheets if everything looks good maybe I have a go:ninja:
 
Hmm, basically I meant its a no go, what you do with it its up to you :)
Meaning its not a way forward, so Im not going to take it anyway.
I usually say if a combination is good, dont touch it, and I wont.
Sunday tracking it they think its stock because of the stock canister, but its not and I tagged along the quickest rides, call me infantile at 47, I LIKE that **** :) Struggling for 12 mentally :D

Hello TomTom

do you have a part number for that KTM450SX cam?

and I note that although you quote the KTM cam figures, you don't quote the Husaberg ones?

which I have here.

the Husaberg has two rockers with cam follower bearings. the KTM has an inlet rocker with no follower bearing.
