Coast to Coast
Well, I picked this XL75 up a few weeks ago and finally got it running. The carb was so clogged I put an xr100 carb on. Coil was a "universal" 6v/12v thing that must not have liked the AC supplied to it, so with a proper coil spark was much better, new points and it has a bright blue spark now.
Mechanically it was definitely attacked by someone who shouldn't work on vehicles. Swingarm pivot bolt was a too small carriage bolt, so at the axle it had probably 1 1/2 -2" of side to side play. Rockers probably hadn't let a valve shut fully in years. Brakes obviously stuck. Enough mud around the countershaft that the chain was stuck.
So now that it runs I know the jetting is off, it bogs bad if you try to rev it fast. It burns enough oil that it's probably not helping things. So eventual plan is an xr100 motor taken out to 120cc with a cam. Currently I'm going to fix up the original motor and maybe use it for a different project later.
Chassis wise I already swapped on a XL100s swingarm, it's longer with shock mounts in the stock location. I want to lay the shocks down, probably make my own parts for that. Needs new seat foam. And it will need all new lights if I ever want it on the road again.
