Progress - motor work - Project 73 CL175
« on: Apr 07, 2008, 23:29:27 »
well, i guess i started my project today.  i have a 1973 CL175 and CL350.  i think ill make different posts for each bike.  at this point ill be working simultaneously on them.    well here is what i started with.   missing forks and rear brake lever.  



and after a few hours in the garage today i took off the tank, lights, fender, and carbs, drained the oil, and cleaned the engine a little. ill be ordering carb rebuild kits and figuring out a front end.  once i rebuild the carbs ill see if i cant get this thing to start. this is where im at with the tear down

started cleaning one carb

i should have taken a picture of the wiring in the headlight, but here is my wiring diagram so far


if anyone has or knows where a manual for this little cl175 i could sure use one. thanks

Do you think that the wiring is much different from the CL350? I would think the color codes would be pretty constant. After all.. UJM.  ???
If so, I think I saw some links to the wiring schematics/diagrams for these bikes. I will see if I can turn it up.

BTW, I like it. Looks like a fun little bike. I think we could use one of these too. Oh no, I already swore I would only have one vintage bike. Right... next one is more modern. Gotta have one for going to retrieve parts for the other.

Here we go. Got it from Oldmanhonda.com. A really terrific site.

What a killer bike! Do you have the triple trees? If so, I'd measure the ID and see what forks are available. Of course, the easy thing to do would be to just buy some stock ones (it's the route I'd take).

The wiring on that bike looks dead simple. If you aren't going to use turn signals and just need a basic wiring system, the wiring diagram I used on the CL350 will work fine.

I suggest keeping that little guy as light as possible. It will be fun.

yeah im fine with the wiring.  those were just notes so i could get it straight when i put it back together.  all the wires are color matched so it should be easy.  the forks i need are 31mm.  so im just trying to find some.  the only ones i have come across on ebay are trashed.  im going to a salvage yard on fri to see what i can find.  today since i have no  parts and i am waiting for carb rebuild kits i did a first mock-up for a rear cowl



 i want to get the forks and bars set up before i start making the actual seat.  i think im going to have to go with rear sets because this thing is so small.

So you have the stock upper trees? It might be simply a matter of having a couple mm's machined out so you can go with 350 forks.

Since you have a 350 right there, have you tried the 350 trees and forks?

holy shit.  my brother is a machinist.  why didnt i think of that?  i can find 33mm on almost any small cc CB.  it would only have to come out where the trees attach.  that would take a few minutes on a lathe.  looks like im going to go take off a front end right now
thanks chris.  these forums are invaluable

The cb175 uses 31mm forks as well. as far as rear sets go you can use the passenger peg mounts on these no worries. just flip the gear change lever around and change GP style then all you have to worry about is the brake side. ohio cafe racers and clever dog racing have some really good info on 175 racers that you can apply to this project. here are the links.

No prblem buddy.

So did the 350 trees and forks bolt right up? If not, your brother should help you out nicely. Keep us posted on the progress.
