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

Glenn
