S90 Now Full Wave – Can This Finally Be It?

So the fact I had not been writing about the S90 is a give away of how I had been feeling. To be precise, it has been one disaster after another. I won’t mince words when I say the previous guy that tried to do it was a complete waste of time and money. His lone mechanic was working on several projects at the same time. Sure he may had been competent but the fact he could not devote his time to mine just resulted in a half baked effort.

Here’s a video I received this morning. It’s running now, with a ‘full wave’ 12v electrical system. When I asked the mechanic if it was normal now, he said it was ‘perfect’.

But before that, let’s go back with a thorough history.

S90 Update 11 – Carb, Headlight & Piston

New purchases this month: Fork bolts, timing chain sprocket, timing chain guide, clutch plates, camshaft.

S90 Update 10 – Carb, Headlight & Piston

I managed to find a new piston from a tricycle driver in Tarlac I found on FB:

S90 Update 9 – The Seat

Ok so the seat I bought last July turned out to be pretty bad. Some people say I could still use it possibly by painting over it with clear or something but I don’t want to. It’s a goner afaic. And so I went ahead and looked for a pre used Honda metal TMX seat. Believe it or not despite the TMX being incredibly popular it’s still very hard to find a metal one as most seats now are plastic. I chose metal so I can bore and weld it. I managed to find one after weeks of searching for P500 from a cafe racer modder on facebook who had it lying around his garage.

Here they are:

S90 Update 8 – Transmission Issues

So, I’m screwed. Here’s a pic of the 2nd gear of the original engine:

S90 Update 7 – Magneto Repair

I am fascinated with the magneto, and how it allows for a self contained engine that produces electricity to power the spark plugs which then powers the magneto and back again. No matter how much tech I learn I still find that idea absolutely amazing.

As you would imagine mine being 50 years old was worn out either by wear and tear or the elements so I had to get it fixed.

S90 Update 6 – Wheels and Tires

The bike came with 1.4′ rims (I think), and 2.50-18, 2.75-18 tires front and rear. They’re toast.

If a rim is that bad the tires can’t be any good either. They’re the ‘Sony’ local brand you can find only at Caloocan and in the provinces I think, preferred by tricycles for their super low price but relative ok durability for hauling stuff around.

S90 Update 5 – Bought parts, Received Blasted & Painted Parts

Ok where do I start.

I now have the frame, fenders, swingarm etc. back. I had to return the fenders though because the ‘aluminum’ color I chose turned out to be too white. I replaced it with ‘secret silver’ which should be the ‘silvery grey stock metal’ color I am going for.

S90 Update 5 – More Prepping

Yesterday I separated the shiny bits from the donor gas tank. It’s in great shape.

S90 Update 4 – Prepping for Sandblast

Lots of things have happened since my last post ten days ago. Five days ago I picked up the seat and brought it to a upholster who removed the foam and showed me this.

Clearly it’s a mess. I’ve decided I need to compare it to a TMX seat and see if I can use that instead. I just need that hook thing at the top and those two bolts to the rear that connects to the frame.
