today in the middle 50s. I rode to work today.  yesterday about the same. did a small group ride for NYD.

finally got the new rotor for the CDI from Vape, John at Economy was a huge help

and its good, only thing i had to do was trim back the ignition winding base a few mm to clear the rotor. (its just plastic but you have to be careful)

Bike was dead cold, hadn't started in a few days (in the vid).

used a piston stop after motor was set to 1.7mm btdc, then put a bungee on the kick starter to hold it in position. was pretty easy
NOTE: the rotor that worked was a A70R-94  THE '92'  is the ke100 one that i had to use the taper on. that '94' rotor needs to be asked for as i dont think its on the website directory

great work  Looks like there's a little groove in case ahead of the CS sprocket- is that manufactured that way or chain wear from a previous owner?

Very cool.

I wish I had half of your mechanical skills and know how.

its made that way.  the next year or 2 had a hi lo range, and that casting was open and integral to that. however in early 67, they hadn't implemented it yet, so thats why it has the weird dual rear sprocket.  its a really odd bike. and thanks, I was determined to update the electrics for years

then there was this..    had the go pro running so .. the stud pulled and headgasket went kaplowie.  luckily no real damage.

[RDnuTZ]

bummer. Stud just back out a couple turns or actually strip portion of itself and/or threads in cylinder?

[m in sc]

threads in cyl gave up.  repaired that last night, installing now.  I mean, thats all part of it. 

heres the video.

Doh! Glad it was an easy fix with no other damage than the threads & gasket.
