To Camshaft or Not to Camshaft....

Sounds like I'd be better off leaving things as they are for the time being. As you say, most of the time I'm in the low and midrange powerband - though I do occasionally go screaming down the road in the higher range. Maybe if somewhere down the line there's something else with the engine that needs attention, that might be a good opportunity to look into this. But I think your suggestion to stick with the stock cam is probably best.

I will not install cams other than stock in the engines I rebuild. ................lm

Sensible advice which I tend to stick with. Sometimes though, it is just nice to experiment a little and see what happens.

Vince, you haven't experienced what that motor is capable of until you fit a decent cam.

CYB cams are basically very mild and would be fine on the street. They are not too hard on valve parts and just add a little more push.

When I started racing I tried every Norris cam grind and some were really hard on valves. And then we came up with a combination that made for amazing acceleration - but that was on the race track.

For the street I'd suggest you start with the mildest Megacycle grind. You are correct that they take your cam and grind it and weld it and grind to a final profile. If you don't want your bike off the road and stripped while you wait for the cam to be machined you need a spare core and it has to match the one you already have, so deep splines or shallow is important.

I probably have a set of cam cores you can have for a reasonable price and I think I still have a couple of freshly ground cams but I'd have to check what's in stock. I did have a mild one but can't remember if I sold it. I could check if you are interested.

Sure, let me know what you have. Thanks!
