'71 CB175 - Cafe Project
« on: Oct 04, 2011, 03:35:31 »
Hey Guys,
Picked up a pretty nice 71' (incorrectly titled a '72) CB175 today. In okay running condition. Carbs need a bit of work (go figure) The left carb float was half full of gas, so anytime you revved it would flood badly and drip gas everywhere. Most of the electrical works. The chrome was is great shape, the front rim is nearly flawless. As I dug into it for awhile tonight I noticed a couple oddities from the previous owners' attempts at customizing etc. If you see anything odd in my pics feel free to throw in your 2 cents as I am not as familiar with the CB175's.


Some things I noticed:
Retarded stickers everywhere and hipster feather
Nice little mini turn signals
Dirt bike foot pegs
Rear fender and taillight are kind of a mess, and both fenders obviously chopped
Aftermarket rear shocks/springs (Hagon, I believe. Good/bad???)
3" rear tire. Seems really small, pretty sure its supposed to be a 3.5"


Im sure Ill find some more. Here are some pictures, she was really dirty, but cleaned up surprisingly well.

QUESTIONS???


***Is it possible to repair a hole in your carb float? The hole is smaller than a pin head. Would a tiny drop of solder do?


***What is with the intake extension things?(the tubular lengthy metal mount for the carb) Are they necessary, I know I have seen some CB175's without them?



***3.5" tire should have no problem fitting on the rear? I am pretty sure thats the stock size, just need to double check before I order one. (Just found a service manual and checked tire sizes. Apparently the front is 2.75 and the rear is 3) That's so small on the rear, I am sure a bigger size will fit. I'll try and get a better pic of the space.


***Fork tube diameter? I am thinking clip-ons may go on this bad boy If I can find any that don't cost an arm and a leg. Do any modern bikes have the same diameter? Will a metal shim on a larger diameter clip-on work, be safe?


More to come

Nice looking bike. I've never tried to repair a float, so I can't help ya there. But the carb mount (metal one to the engine) is needed. Or else the carbs would be cocked at a very odd angle. Check out Pirelli tires (if nothing else)- they have a 3" tire that I used on the front and rear of my 68 CL175. Or you could lace up another rear wheel to your front hub. And I'm almost positive the fork tubes are 31mm.

Hope this is as sweet as that 350 you built. Looking forward to it.

Those Hagons are complete junk, you should take them off and send them to me. Ha. They are much nicer than the stock shocks.
 
Nice little scoot, man.

Did a good amount of tinkering today. I reassembled the carb that had a hole in the float after I patched it with a very small amount of solder. Synched both carbs and got the idling set. Bike runs great now. Now I just have to clean this sucker up and get it looking snazzy.



I am going to try and make this a drivable project. We'll see.
Anyone put rearsets on a cb175?

I believe Motobits makes them for the vertical 175's. You might have to do some work to clear the stock exhaust though. Or look for some CL pipes.

Cool, I'll look into that. Yeah I am not sure about the stock exhaust yet. I am pretty sure it will go at some point, just have to find a nice replacement. That being the case.


Anyone want to buy the stock mufflers?
