[QUOTE="ClassicBiker, post: 118659, member: 1632"] Having just installed the sealed valve guides in my Shadow here is what I did. I installed the valve guides. I installed the valve guide retainers, snugly. I reamed both at the same time. Before final assembly I made sure that the valve itself would move easily through the lower guide, retainer, and upper guide. The way I made sure the lower guide was co-axial with the upper guide was I turned piece on the left. The major diameter was turned to match the diameter of the upper guide and the hole was reamed to match the diameter of the reamers I used to open up the lower valve guide and retainer. The face, major diameter, and the diameter for the reamer were all done after the minor diameter was turned. That way the major diameter, the face, and the i.d. are all relative to each other. The hole in the old valve cap on the left is clearance so it does not influence the reamer. The spring is an old Triumph inner valve spring. When all is assembled in the head reamer guide is positive located by the counter bore of the upper valve guide. Once I had reamed the valve guide, I removed the reamer guide. I then placed an upper guide in the head and held it in place with the Triumph spring and the old cap. I then took the valve for that port and made sure it slid through both guides and retainer easily. I gently cut back the valve seats by piloting the Neway Valve seat cutter on both the lower and upper guides. The upper held in place as I have already described. Then I gently ground the valves in piloting in the same way. Once satisfied I disassembled and stored all the parts grouped together for each port. Cleaned everything to within 0.001" of its existence. Making sure there were no traces of oil, cutting fluid, or grinding paste. I installed the seal in the retainer and applied Loctite RC 620, tightened it up by hand as hard as I could with the tool purchased from the club. I let is sit 24 hours to cure. I then assembled everything. Once I got the wires to the coils of the BTH the right way round it fired up and no smoking. Given the current state of affairs I haven't had a chance for a ride but I have started it regularly, once I replaced a leaking gas tap, and have checked that I'm getting oil up to the valve gear. As you're doing a valve job I would also suggest getting the V3 seal set as advertised in MPH. The pdf has the dimensions of the reamer guide.
