Today, with help of Trixie's miniature hands, the valves were set on my '20 GTS300.
The 'healing' (re-assembly) can now begin in earnest.
The Vespa has been resting on my table lift in a suspended state of general unusability for what I think must be, seriously, eight months.
I know, I know, it's a shameful situation, but I feel that I can now muster the mental inertia to get it back together, cleaned up, and parked at the Pump House coffee shop in Deadwood at 7:00 AM on Tuesday morning.
Tomorrow morning, I will spray the muffler with a fresh coat of flat black heat-resistant exhaust paint, then, while it 'sets', I will install the new valve cover gasket, spark plug, new air filter, screw, jiggle, and cajole everything back together....hopefully, and start it up later in the afternoon. If everything goes back together as it should, I will have it zipping down the road by 5:00.
I ginned up a special-use short flat blade screwdriver to work in the confined exhaust valve adjuster area by super-gluing a driver bit into a small socket. It worked rather well for this purpose, and with an 8mm open end wrench, was able to get things into spec, or very close to it.
The exhaust valves were tight at 6700 miles. Now, the .15 feeler gauge slides in and out with a slight drag, but I can still force a .20 gauge into it but it isn't easy, so I'm leaving it as it is, being better a tad on the loose side than too tight...(or so I've heard).
I bought a small round swivel mirror to help see when the TDC hole in the cam sprocket lines up with the line mark on the cylinder head.
I also purchased one of those extendable magnetic wands to fish out the steel tools and misc bits that were dropped down into the scooter's dark innards of the engine 'bay'. Very handy piece to have....often.
Anyway, I am very pleased to be able to report some real progress today, and post a legitimate scooter-related post.
Please keep it in mind that I am NOT a mechanic (or is it 'Technician' these days?), and this kind of service does not come easy to me, and if there was a servicing Piaggio dealer in my region I would be happy to turn this sort of thing over to the pros, but necessity requires another route, and so here I am, white lab coat, Buddy Holly heavy-framed spectacles, a wife with very handy small hands, and a willingness to help when needed to get this little bike off the table and back on the Black Hills backroads dodging whitetail deer and wild turkeys, as well as the occasional radar-equipped Meade County deputy.
Several relevant photos are in order...
