Front Number Plate

I've actually been fiddling with Salty a bit the past week, but don't have much to show for it. One of the items I did manage to complete was a front number plate. Which is pretty much a piece of plastic cut to shape. I'm not exactly sure why it took several days to put together this little item, but it did!



At least Salty has had some company, since Ratty has been hanging out next to him.

Hey Chris, I know you didn't get into this to solve technical issues, but I thought I would give it a shot. I took the Cylinder case off of my c110 to clean it up and such, but now I am having a problem getting it back on nice and flush. The bottom of the case and the head aren't matching up and there's definitely a compression issue as a result. Any thoughts? (I know that is super vague, but this is my first rodeo.)

The actual mating surface between the head and the barrel is at the very top of the barrel, where it slips into the "recess" around the combustion chamber. If that makes any sense. There is a thin copper ring that provides the seal. Make sure the barrel is sitting properly in that recess. There is quite a bit of slop as the head is lowered down the long barrel studs, so you have to make that connection fit.

That copper ring is what seals the combustion chamber.

Also, there are three o-rings that go between the head and barrel for oil control. These can be somewhat fiddly to keep in place when fitting the head onto the barrel.

Here is a pic of the top of the barrel, showing small grooves for the o-rings to fit into:

Hope that helps,

Yeah, the O rings are definitely tough to keep in place. Well, when off the bike and off the cylinder studs it seems to stay pretty flush. It's just when I try to slip it back onto the studs that I find the gap. I figure there is going to be a little gap, but I don't know. I'll get it. Hey, thanks for your help and your blog. I really enjoy it and it has given me some great ideas.

Hello Chris

It is good to see you're inspired to start back into working on the bikes. Making time for hobbies like this isn't always easy. Now that you're back, I'll have to re-start the habit of checking in on your progress. It has taken me at least three weeks so far to create just a cardboard mock-up of a number plate and box to hold all the electrics on the front of my project bike, so one day for your number plate seems lightning fast!

cheers
Angus
