CBR400RR and VFR400 cams and gear drive tooth counts and diameter measurements

Post by ruckusman »

Hi guys,

Hoping that someone may have these parts available to do some quick measurments - unsuccessfully staring at ebay listing images has given me a headache.

Looking for some basic numbers, cam gear tooth numbers and idler gear tooth numbers and gear diameters for the CBR400RR NC23 and NC29 and the VFR400R.

If anyone has parts accessible for easy measurement I'd really appreciate it.

thanks

BUMP

Anyone out there with some of the parts available to take a quick count and measurement?

On the VFR400/RVF400 - an accurate tooth count and measurement (a tape measure will suffice) of either the first idler gear in the cassette or the camshaft, both would be good - a tooth count of the crankshaft will tell me the tooth count of the camshaft - I think it's 21:42 but need to confirm.

For the CBR400RR because Honda updated the NC29 - I'm trying to figure out what the module is of the gear teeth on both (I think this is what Honda changed) - so a tooth count of a crankshaft (this will tell me the tooth count of the camshaft) and a measurement of an outside diameter of a gear an tooth count.
