1968 CL175 repair and build
« on: Sep 23, 2016, 04:11:20 »
Hey folks,

I just bought my first motorcycle, a 1968 CB175. I guess it's a sloper according to the year and the title, maybe someone can confirm with the only picture I have right now.

I got it from a friend for a decent price, and it's in great shape including factory paint on the tank. I've got two issues right now that I'd love feedback on, and I'm reading about this thing every free moment I have so I'm not totally helpless.

Issie one is right now my right cylinder is not running. The carb on that side was overflowing gas through the tube so I figured the float pin was stuck and replaced it, but after starting it up and having a cold exhaust on that side, I've learned that something's up. I'll be trying to run it just on the right side tomorrow with the left side spark plug lead and checking the plugs to get an idea what's up there.

I also have a leak from the camshaft block on the left side, and I'm hoping that's just a gasket issue or maybe an issue with that cover.

Anyway, it doesn't need much restoring, but it needs a little love to get moving and I'd really like to have a running bike before winter hits us so any input would be appreciated.

Thanks in advance, and I'm really looking forward to this little project!

Yup. "Sloper". Note how the jugs angle forward instead of vertically. Great bike. TONS of info online as they are super popular machines in the vintage road race world. I actually have a 68 175 sloper motor and frame. May have to do something with it someday lol.

Looking forward to seeing what you come up with and welcome to DTT.

Oh... And that's a CL175, not a CB.

How can you tell the difference? It's titled as a CB, so it'll end up registered as a CB and I'd prefer to correct that if I can.

Check the VIN on the frame neck...

Nice little bike. For the running issue, first make sure you have a strong spark on that side like you mentioned. I would then go through the full tune up procedure: cam chain tension, valve clearances, set timing and then carburetor sync.   That should remedy your problem.

And a side note...

From the pic, that bike looks pretty damn clean. If it were me, I'd do a thorough cleaning. Replace what NEEDS replaced. Get it running at 100%. Touch nothing else. The early bikes are getting harder to dig up in original condition and doing a "restoration" can actually lessen the value.

Agree, check the VIN against the numbers shown on this site: http://www.motorera.com/honda/index.htm#y175

Also, based on the little bit of poking around I did, the CB175 wasn't built until 1969, but the CL started in 1968.

this helps a ton, thanks!

I don't plan to do the whole full restore thing with new paint and powder coated frames and blabla, I plan to just clean it up a bit and maybe rechrome the fenders and clean up the used-to-be-shiny bits. Honestly i wanted a 360 to do a full cafe thing with but this one was cheap and in fantastic shape, and I should br able to fix it up and double my money, plus I've ridden a motorcycle four times in my whole life including yesterday so not dying seems like a good idea.

I'm gonna hit the gym and head home to switch spark plug leads, and then tear into the carbs anyway so I'll update soon hopefully heh.
