Honda CB100 Cafe build attempt by mackhina

Hey all

I've been reading through these forums for a bit and thought it was time to introduce myself and post my attempt at making a cafe racer! I've just bought a Honda CB100 so it wont be the most impressive bike here, but for me it's a good bike to learn on and it wasn't very expensive.

My bio for no particular reason: I'm from Newcastle, Australia and currently studying Mechanical Engineering when I get the time. I'm 28 and I've never ridden a motorbike. I also a own a Valiant Charger and its been stealing all of my cash for the last 5 threes, so I'm having a break from it so I don't set it on fire from frustration and I'm trying my hand at a smaller project.

I'm not going to lie and pretend I know anything about bikes. Its a very spur of the moment project. I was walking home one day and saw a Ducati cafe racer. Went home and googled "classic bikes", did some research and then decided I wanted my own. Unfortunately my lack of money and bike skills made me buy something a little cheaper and less powerful.

I picked it up a few weeks ago but with Uni I haven't had a chance to look at it. Today was the first day I took the tarp off my bike and got out some tools.

Enough talk though. Picture time!

I've got the original seat, but I'll be ebaying that to recoup losses. Its huge and not really cafe racer-ish. Apart from the seat being missing this is exactly how I bought it.

From the other side.

The last owner had been doing it up himself apparently but had gotten jack of it. So he sold it and I picked it up for $630.00 of ebay with the only setback being a 6 hour drive to get it.

The frame had already been painted, but it's showing signs of rust all over it so I plan on stripping it back and starting again. There are also fenders for it that I got in a primed state, but it looks like he had primed over rust, as there are signs of bubbling and pealing under the primer. I'll probably see if I can get away without them!

I've ordered a new tank off ebay and I'm going to try make the seat myself once the tank arrives and I can get a better estimate of what it will look like with a tank in place. There's some pretty good tutorials and hopfully I can find some more when I get a bit closer to being ready to work on those parts.

Well that's the start. I'll post new picks as I get more into it. All comments and advice are appreciated! I'll need all the help I can get!

Cheers

Cool man! Welcome. I am finishing up a similar bike (cl100) right now. Good news is, it's a very easy bike to work on.

Are doing a engine rebuild? Or only external mods?
 
Thanks for the welcome!

Glenn, your bike was one of the reasons I thought I'd give it a shot. I saw it on ebay a few times and read the pipeburn article on it. Very tidy job, escpecially considering where the bike started.

Dont think I'm going to do anything with the engine though. I would like to pull it apart to have a look, but I'd like to give the stock a shot and learn how to ride it before doing to much. I imagine once I get the hang of it though the stock might not really cut it in the future.

My builds on hiatus though for a week. Striped a thread, then the extractor screw snapped off in the bolt. So i've ordered a heavy duty set. From US though so I have to wait.

Was wondering if anyone had much advice on changing the front forks over? The current ones are really pitted. I was thinking of replacing them and putting a disc break on the front if its not too much work? Just got to find out what a good replacement would be without too much work. Might start a new thread though so I get some more answers.

Cheers
 
Shamone!

It's not what you've got, it's what you do with it!
Good choice of bike! I'd say if the engine is fine leave it alone! Save from maybe intake and exhaust of course.
Apart from running like tickety boo sewing machines they will go to the moon and back on a teaspoon of petrol.
Drink plenty of Sol too, seem to work well down there.
Is'nt Newcastle the place with all the funky letter boxes?
