GUIDE,BSA A10+.002 P.MACH
A .002 in. oversize valve guide listed for the BSA A10.
This is a valve guide listed for the BSA A10, machined .002 in. over standard size. The part number carries a plus-.002 oversize designation, which tells you it's meant for a bore or bearing surface that's been machined out slightly from stock, not a straight replacement guide.

Our records on this one are thin — it's not something that shows up often in the catalogs we pull from, and there's no additional fitment detail beyond what's printed on the part itself. If you're working on a BSA A10 and think this is the guide you need, give us a call and we'll go over the specifics with you before you order, since oversize guides like this one need to match up with the machining already done on your head.
Worth noting this is a BSA part, not a Triumph part, so if you came here off a Triumph guide it's not going to be the right cross reference.
