1980 Honda xl185s.... decisions.... decisions

Post  jfg75 on Tue 8 Dec - 4:11

Ok here is the PLAN. I have a 1980 honda xl185s. Its an old on/off road bike. Although I love cafe racers and would love to build another one. From looking at the cb125 builds the frame is pretty much identical. Correct me if I'm wrong.

So my question is dare to be different and build a cafe out of a dirt bike or drop the idea?

I think you build a caf out of almost everything! Just shorten the front fork tubes and use shorter springs in the rear and you are on the right way. The Xl seems a nice and light bike to mess around with so you could give it a try. cheers maybe you can make it into a scrambler caf.....

I'm sure it's possible to build something very interesting out of this.

hello,

I've installed the XL 185 engine in a frame of an old CB 125, look at my post:

http://classicbikes.actieforum.com/show-us-your-project-f1/some-pics-of-my-honda-cb-185-caferacer-t217.htm

The advantage is that the engine of the XL has much more torque compared to a 125. Shorten the front fork, or put a fork of a cb, put shorter springs and/or a swingarm of a cb. You can also make a streettracker.

if you plan to use another frame, the dimensions of the engine are rather the same as the engine of a 125, you just have to make new brackets to hold the engine at the cil.head.

Good luck!

What is the best way to shorten the forks? I think I am going to build a cafe out of it but who knows your mind can change in the middle of a build.

Hi JFG75, it`s easy to get some road fork tubes, than to cut them down, cause you need first a big lethe and know how to work on it. Next step is to cut down the inner springs correct, and cut a new finethread inside - thats not easy!. You need a lower wheel 19" for example, and at first you can push the forktubes through the brigde and find out what`s a good position for a street bike before you ruin the fork - but look at mine - scrambler works also and your trouble is far away!!

I agree with andreas,

for less then 100 euro you'll find a fork on ebay. If you still want to do it yourself:

Merry xmass folks!

I used a Keihin carb from a cb 125 1976, withs the jet and needle of an xl 185 1982.

If you want the exact specs of the Keihin, i can search in the manual.

I think I still have a Keihin of an XL 185 1982 with inlet manifold

I have the inlet manifold. Is it a working carb or does it need rebuilding?

I needs new jets and needle, for the rest is everything ok. I just saw that you live in the states, it's more economical to find a carb on ebay usa, no?

Well that must be not all that difficult concerning the metal (polished) bars instead of rearsprings Shocked

Thats what I am hoping. I like the fat tires. I am going to cut the frame away from the fender so tire clearance will be my main issue i think.

The best method is to decrease its travel by
preventing it from rebounding to full lenght.
Remove the damper rod (#12)and you'll see the
"rebound stop spring"(no #) under its piston.
Install a longer spring or an additional tube
of suitable diameter and lenght. After re-
assembly you just have to shorten the pre-
loader (#16) on top of the main spring and
you're done.




Best regards
Sven

edit:
silverCR750 shows in his thread how he did
it. It's exactly what I meant, the forks are
being lowered by the measure of the alloy
tube between spring and piston:

Thanks for all the help. I hope to get it really low. I think clearance with the tire size on the rear will be a problem but we will see. Cant wait to start. Thanks again.

You need to remove the "E-clips" from the little axl where the wheights are mounted on.

Another way to get the front of your bike down to put the fork-tubes thru the holders a few cm's so the lenght of the fork stays the same but the bike drops a few cm's

I found two black rubbers to put on top of the fork so it looks a little cleaner.

From the parts breakdown image I have, the weights and the bracket are all one piece this is why I asked the other questions. So I took the weights off and now the bracket is not coming still.... any help would be great!

looking very good, bud that frontfork is really not done!
look for a fork of a cb or tomething, for a couple of dollars you can get one, i really think that should look so much better.
bud anyway, really good looking bike.
