VALVE GUIDE 650/750 +.008
Oversize (+.008) valve guide for 650/750 twin engines, fitted when the guide bore has been machined oversize.
This is an oversize valve guide, sized at +.008 over standard, for the 650 and 750 twin engines. Valve guides like this get fitted when the original guide bore has worn enough that a standard-size guide won't seat properly or hold the valve stem true, so the head gets bored out and this oversize guide is pressed in as the fix.

The catalog lists it as +.008 over, which tells you this is meant for a head that's already been machined to accept that oversize, not a straight swap into a stock bore. If you're not sure what size your head has been bored to, check with whoever's done the valve work before ordering.
Our record on this one is thin beyond the basic listing, so if you need confirmation on which specific 650 or 750 applications it's cut for, give the shop a call before you order.
