1974 CB125 project
« on: August 09, 2013, 10:32:00 PM »
This one was unmolested (compared to my previous motorcycle purchases which had been worked over by poorly trained monkeys) but had been parked for many years.

Major disasters include:

Carburetor: Lower body around jets oxidized away.
Front Disc Brake: Rusted solid, parts not available.
Throttle Cable and Front Brake Cable: Rusted solid, no longer manufactured.

Success stories: 
Replacement carburetor body sourced locally.
Front disc brake was attacked with penetrating fluid and naval jelly and moves after a week.
Cables can be custom made by Motion Pro.
She has decided that she likes this one (quite a surprise since she mostly ignores the others).

My first "real" bike.

We didn't have disc brakes here until later though.

Replacement carb body acquired, cleaned, jets swapped and installed.
Chain cleaned and lubed.
Throttle cable finally broke free after several weeks of penetrating fluid (still needs replacement due to broken strands at the handle bar)
Front disc brake caliper de-rusted, bearings replaced, might work if I can get a cable.
New battery installed.
Drained, flushed, refilled front forks with clean oil.

Put gas in it today, and it started on the 3rd kick!

Still need:
Front tire, tube, band
Rear tire, tube, band
Front brake cable
Side covers
Petcock rebuild (gasoline was dripping)

Dave Silver in the UK says he can order in the cable at £25 ish, but for your info it is the same as a CB200 if you can find one of those

My first bike was a '72 CB125s & I used to ride 13,000 a year commuting to Navy College, rides out, running around & generally having fun. But after riding bigger bikes I sold the 125 to a friend who passed his bike test & went on to become a bike cop.

Goodness knows where LMD 58 K is now...most probably in bits somewhere...
