that cam profile is for the old bikes. it says '600' for a start.

totally different set-up on the LDC engines.

The grind number has no significance in relation to the bike generation.

It may be that this cam is for the older bikes but it cannot be concluded from the grind number.

yes it can be concluded from the number! it was about for the 600cc engine 15 years ago! it's probably a Lineaweaver cam profile and he'll have got it from someone else who knew someone else.

the 570 is a totally different set-up. totally....

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.

it is true to say though that both cams fit a motorbike engine. this I will concede.

Can you source that claim?

In comparison, how are the DR-Z cam grind numbers related to anything? Web Cam Inc. - Performance and Racing Camshafts / Suzuki DRZ 400 (MC) (00-13) DOHC 4v

293? 536? 288?

I'm not saying you're wrong about the cam being for the older bikes - thanks for that information.

No idea and don't care.

don't make the mistake of thinking I don't know more or indeed; 'don't know it all', I may well do. but as a result of working closely with the site troll and the extremely biased view of those that know less I know that argueing with you is a waste.

I have much more to offer but have no intention of doing so.

Well if you have no intention of adding anything constructive, how bout you crawl back under your rock you fuckwit.

If I have ballsed it up that's fine, I'm not a mechanic or engineer or cam guru and will be quite happy to be shown my mode of failure.


This guy may be able to help as well

Web cams can grind that 600 or whatever profile you like.

Answers direct questions with "you don't know things! I know things!". Doesn't say what those things are ...

Seems to think it makes him more trustworthy!

Re. cams, here's a tiny bit of info from KTMtalk:

KTMTalk.com

KTMTalk.com

Looks like the 570 cam is the performance cam ...

Doesn't seem to be much in the way of cams for the 510cc up XC4 head, which is what the 'Bergs are. If you find a performance cam for the KTM 530 it stands to reason it could possibly work Caveat re. timing in KTMtalk thread above.

Currently I know of only berglsmerg's 610 that has an aftermarket cam in it. It's from Thumper Racing right? I'd give Thumper Racing a call maybe.
