Another C110 race bike....almost done

Spent some time on the ignition last weekend, turned out the new rotor I ordered had a fault in it. When I replaced it with yet another one, it started right up and let me set the ignition.
Another step closer to finished. just waiting for the seat to come back from upholstery.

I don't blog enough

As the title says.....
But still working on stuff, just busy with a job and life and such things.

Current project, still, the second C110 race bike. And rebuilding the SS50 race bike after a slight mishap.


Changed the build to a different frame, where someone had already cut the rear end off.
Engine built with 50cc, race camshaft, race valve springs, heavy duty clutch springs and a shorter 3rd and 4th gear for 3/4 of a close ratio transmission.

engine stands

When working on engines, I used to use some wooden beams, but they always slid away.
then in the new workshop, I made an engine stand from some leftover bits of hardwood, and this worked so well for me, that I wanted some more, as I get more engines to work on at the same time now.

Today I made three more engine stands, with some slight differences, hardwood, so they don't damage what you're working on, but sturdy enough to be able to use an impact driver, and high enough to put a small oil catch can under it for draining engines.

another Carb

Okay, I've decided against the dellorto for now, didn't really like the non-japanese looks on my mostly japanese bike.

So I've found myself another 20mm powerjet carburettor to adapt to my c110 racebike.
Started making some flanges, using an intake rubber I had laying around.


Bit more modern then the S65 rubber on the other setup, but that is moving over to my C110 streetbike to be a period correct upgrade over the original 16mm carburettor. Just because I use it daily if possible and in modern traffic, every bit of power is welcome. The 16mm with all bits belonging to it will be stored so the bike could be brought back to original when wanted.

Am I asking for trouble?

While I am normally so strict on putting keihins on 4stroke Hondas, I found something funny and wanted to give it a try.
If it works it would be period correct and being a downdraft like this, it would look cool, especially if I could find or make an alloy funnel. But on the other hand, something italian, known to give trouble.... maybe I should think of a keihin back up plan.

New project

Traded some work and parts for some other parts, and now I have another C110 project, going to be another race bike
(So I might sell the other one)
