I just picked up a CL175, so all these small bore projects interest me. I'll definitely follow this.

Thanks for your interest guys.

Hey ffjmoore I found  and read again Big Blue bike build. I really liked that bike when I saw it last year and I actually voted for it for BOTM.

Well I figured out that the 71 CB175 front end won't fit this frame. The steer tube is too short and the wrong diameter to fit. I checked the All Balls site and they give a list of trees that will possibly work as they have the same top and bottom bearing diameters. These are CB125S, 1976 - 85 and CB250 Nighthawk, 1991 - 2008. I read on another CL100 cafe racer thread on this board that the 175 fork will fit, but that information is incorrect. Anyway I have two CL/CB100 front forks so I will make one good set and run with that for now. Also the rear wheel hub for the 175 uses a larger diameter axle. The width is correct though so the 175 rear hub would work as long as the axle slots in the swing arm are enlarged. I have decided to run with the original rear hub also to start with since it will match the original front unit. I'll lace the original hubs to the set of 18x1.85 Excel wheels that I have for the project.

Today I disassembled the bike and cut the side cover tabs off of the frame and the passenger peg mounts off of the swing arm.

My brother is handling the tin work  for this bike and is fabricating a cafe style seat/fender out of aluminum for the project. He has also cut the original gas tank apart and is rolling the dents out and bead blasting the inside. Then it will be tig welded back together and I'll paint it and the seat. While he's busy with the bodywork I'll get the cycle parts and motor ready.  I'm not sure of the condition of the engine so I'll pull it apart and inspect everything and replace anything that need to be replaced.

I'll get some progress pictures up soon.

Just swap out the steering stem.   It comes out by grinding the bottom where it's welded in.   The forks and front hub are worthwhile upgrades.

Hi eyhonda, I investigated your suggestion and it would require a 0.5mm spacer sleeve which is difficult. The diameter of the hole in the lower clamp is 1mm too large for the CL100 stem once both are removed. Thank you for the suggestion though and please keep them coming. I disassembled the two sets of 100 forks that I have and I will put together a nice set. I ordered a set of seals for them. I need to keep the cost down on this project so I am trying to use parts that I already have as opposed to buying more.

List of stuff I still need to find:
ignition switch
6V rectifier
ign coil
AGM battery
top engine mount
rear brake lever and link

I will look into the engine soon and asses that.

Thanks for looking. I have enjoyed reading the other posts on these little bikes on DTT.

6v rectifier is like 3 dollars from radio shack. Works better then any rectifier from the 70's and is much smaller.

Then, you'll have to find a different stem.     Mix and match until it all fits.  I already did it but I used a completely different triple.   It's the chase (ie, research) that makes it worthwhile.   But, like you said, try to use what you have first.
