The blue AS3 is off the bench! I would almost go as far as to say it’s completed but there’s a few things still missing: some original fuel lines that are coming next week, a new rear fender that’s on it”a way too and the wiring in the headlight. A tip when restoring AS3s (AS1s and AS2Js too) is to place a battery rubber on the sidestand to keep it from damaging the exhaust pipe. Another fun thing about this bike is the clip that holds the throttle wire. It, along with the rubber on the rear swing, are missing from almost all restorations. They’re not necessary for driving the bike but they’re essential to get the bikes to their original condition.
The AS3 is almost done now, just missing a few parts. A special in this update is the progression of attaching the Yamaha logo to the engine covers. The trick to getting them perfectly level is lining up the tiny notches on the logo and the cover, a lot of people think that the notches are damage to the logo or cover and think no more of them. The actual attachment is best made with regular two compound glue.
So far in the restoration the only things that aren’t brand new out of the box are the chain guard and the oil tank which have been rechromed by Smethurst and painted by Bassel.
The AS3 is coming along nicely, the engine is assembled, except the carburetors. In this update you can see the easiest way to get the foot rest in place: put them in boiling water for a few seconds to soften them up, drip some washing-up liquid in them to make them slide on easier and voila! The great thing is that the washing-up liquid doesn’t damage the rubber and after a few seconds of cooling the foot rest is in place.
Yesterday work started on rebuildning the blue AS3, for one day of semi concentrated work it has come quite far already. This update is a bit different than other updates, you can see how to mount the stand as easily as possible (without using a ton of force and special tools), you can see how to protect the frame from getting scratched when installing the engine and how to install the generator. The green thing protecting the frame is a plastic place mat from IKEA that costs next to nothing. The mats the frame is standing on are again from IKEA, regular doormats that are turned upside down to get a rubberized surface to work on. IKEA is great for cheap disposable restoration accessories.
The blue AS3 is almost fully disassembled, the outside is as expected very dirty, but the inside is a completely different story! The pistons can’t possibly have driven more than a few miles, they’re still as clean as when they came out of the box.
