1971 Yamaha CT1 – 175
I bought an Enduro. $380
- It runs… kinda
- Cosmetically… it’s pretty nice… but just rough enough.
- The wheels are straight… kinda
- The seat is original and really nice.
- Inside of the tank is perfect.
- Carb is clean.
- Motor has 90psi compression. Probably do the Wiseco piston kit anyway since it’s like $40.
- No title. Looks like I’ll be doing the Vermont shit.
- Guess how many quarts of oil were in it… Zero.
- No wiring on the bike is connected at all, except 1 wire. It comes off the magneto, runs directly to the coil, from the coil, the spark plug wire goes to the plug. That’s it. Does anyone understand how or why that works? Seems like the magneto creates enough current to make the coil fire. There are no grounds… no other wires at all. No battery. Just that 1 wire which goes from the magneto directly hard wired into the coil. Definitely some sketchy shit, but it works. I’m going to make a custom minimal wiring harness.
I just rode it to the grocery store in the snow. Pretty darn fun.
The oil-injection pumps too much… or the engine seals are letting oil by, and the jetting is too rich with the pod filter.
So basically it runs like shit.
And the clutch slips like a mother fucker.
Still cool, and for the price… can’t go wrong.
I’ll say it again… who wants to build dirt bike jumps with me in the sketchy woods near Huntingdon and Richmond street?

1991 Kawasaki Zephyr 550, the ZR550B model to be precise. Tore down and rebuilt by a few friends in Philadelphia from Dec 2021-June 2022. But Chris F gets the most credit for all the hours of paint, welding, and bodywork to make it certifiably fresh. For the full build write-up follow the link at the […]
