Should I change cams?

Does anyone know what cams Harely would use when changing an 88 incher to a 95. I understand that in 1999 the cam bearings where a problem so I assume the bearings have been changed with the new cams. I'm also thinking about installing cam gears instead of the chain. I'd appreciate any opinions on whether I should also change the cams to something that would offer more performance.

I'm not sure what cams you should or can run. But if you want to go with gear driven cams you will have to check your crank run out before to see if the tolerance is with in limits for those tpye cams.

I ran SE 204 cams with the 95" in my 03' RK and it ran awesome. There are a lot of cams to choose from, you just need to decide where in the RPM you want the power to develop.

I was thinking that I can use the same cams and just add the gear drives. Not sure what the run out means.

In 1999 they had a recall on the cams they used because the chain driven gears used a keyway instead of the splined shaft and were prone to shear and do lots of bad things to the engine.

S+S also makes chain driven cams that are good if your looking to save some money or dont want to go gear driven.

The crank run out is the out of align or wobble at the end of the crank, in the cam plate. I think with my SS 510G's the max run out could be 0.003, mine was right at 0.002 so I went with the gear driven cams. Hope this helps.

I have a list or parts for sale in the classifieds, that I would make a deal on if interested in. I have SE203s in my bike and the kit for sale has them as well. Good luck on the decision.
