CL vs CB cam sprockets

Post by Merz64cb77 » Thu Nov 08, 2018 5:26 am

Quick question and hopefully with a quick answer:

Will a cam sprocket from a CL work on a CB?

Ie. 14320-268-030 and 14320-268-040

Cam sprocket.

Yes, they are the same.

I suspect the latter of the two part numbers you quote will be a last issue cam sprocket with shallower splines. This won't interchange with either CB or CL camshafts unless you have the matching (late) spline pattern.

If your camshaft will fit he sprocket then it will work.

Just be aware that the C/CA sprocket, although it looks much the same uses different bob weights and springs to give a different advance curve. Using one of these in either a C or CL engine could give you low speed running issues but possibly not bad enough to be obvious.

Hi DJM,

So you are saying they are the same but different? I can see if I can purchase the splines too

Only the CA is different (bigger bob weights). CB and CL are the same.
