Application chart or experience with the cam motion gs 4 valve

[Guest]

I have a g 21 exhaust wanting to go in a 11-1 1325. Wondering if anyone has a general app chart with what cam goes with what depending on engine combo. Leaning towards 370 lifts instead. Jay says they're near upper limit for reliable street engine. Anybody got something they want to trade or sell.

Working on that. Waiting for a call back he's always been pretty good about it

Cam Motion Specs

Also very interested in learning more about the Cam Motion production line and combo / applications. A description of intended applications and engine requirements, similar to that of Web Cams would be great if available.

I understand that Cam Motion no longer makes motorcycle cams, but their cam design/specs are now being produced by Web Cams. The closest I managed to get is the chart below... (notice the lack of cam descriptions, very useful for the less knowledgeable ones like myself). Rapid Ray might have some suggestions or details to share based on your request above.

I'm personally looking for cam options for a reliable aggressive street 850cc high comp piston setup, in a GS750 with oil cooler and VM29ss w/stacks.

Thanks much! That's a big part. Any ideas where we can get comments on these. With so many different grinds somebody did a lot of development
