Andrews 2S cams

[triffecpa]

So I've got a '78 GS1000 vintage race bike. It's got oversized Wiseco pistons, but stock head and cams. I've got a later model head with the bigger valves, that has been decked '040" and a set of Andrews 2S cams. The cams have .390 lift on both intake and exhaust with 274 degrees of duration on both. Do I need to run hi-po valve springs with these cams? Any recommendations as to what type and where to get them? Any degreeing advice on these? Andrews no longer makes these Suzuki cams, but they are similar to a Web Cam 110 grind. Thanks in advance. Tracy

According to this the stock springs are fine. The document has the timming and valve lash. I would definately check for piston clearance.

Kaiser - Thanks. I found the same page and failed to read the small print.

GSBill - The link that you have there doesn't seem to have any 8 valve Suzuki stuff.

Call Jay and ask...

heavy duty valve springs are cheap motor insurance . If the head is coming apart I would get them. You never know when your going to miss a shift and you don't want your valves floating.
