Finished up the wiring harness today and returned my second jackshaft. Can you believe an Amazon vendor sent the wrong shaft twice in a row, even after I emailed to ask them to check and make sure the correct item was sent. They ended up paying return shipping on two items because someone in shipping is asleep at the switch.
Anyway, here are some photos of my incomplete conversion from Chinagirl to HS 142F. As the photos show, the engine is mounted at a forward slant similar to the old Whizzers. Everything works properly including the engine, the lights, the horn, and the ignition key.
A standard HS exhaust is on its way from Bike Berry (Like everything, they're costing a pretty penny these days). I might fabricate a 28.5 inch Quinton upgrade after I get my welder for my birthday.
Once I get my longer jackshaft from Affordable Go Karts to accommodate the wider engine, I'll design the pulleys and Whizzer-type idler clutch for the drive side. It will operate from the locking clutch lever to make shifting "close at hand" and non-distracting.
A 415 chain drives the secondary to the shift kit sprocket. I haven't even ridden this thing yet and I'm already wondering why I ever installed a Chinagirl with all its drawbacks. Still have to install 26" fenders. The ones on the bike are 24 inchers and don't fit quite right.
Finally, thinking about adding a small sealed battery and regulator to even out the lights. I put one on my last build and it worked really well even though my home made lighting coils only generate a couple of amps, plenty to keep a battery charged.
After I get it running again I'm sure it'll take hours to tweak the design. For example, the air filter sticks out too far and needs a 45 degree elbow to swing it in toward the frame for better clearance. And like Diesel Tech, I might experiment with carbs better configured for this application. Anyway, thanks for your interest.
Nice looking build you got going. Cant wait to see your finished ride. Btw did I say that's a 
Nice Looking bike.
