Valve Springs/Cams
I am looking at getting new Cams and Valve Springs for my 2000 DS650.
Can anyone suggest good Cams that they have had good luck with?
Also, as for Valve Springs, I have found some titanium ones at Alba and some Shim Under Bucket Racing Valve Springs for twice the price of the titanium ones at On-Dunes. Can anyone tell me the best one, and why the huge price difference?
Thanks

Just remember one thing when you replace valve springs. The hardware to compress them the more power it robs from the motor. It’s simple. The tighter they are, the more power goes into compressing them. If there is not reason for it, do not change them. The aim is to get the softest valve springs you can, without causing valve bounce at max RPM.

His cams are similarly priced to the RWR cams. I believe there are a few people on this forum running his cams.
