Re: 70's Stingray build
Are you planning on a wider crank? I would if I were you, if something goes wrong you can always pedal. Some say its too hard to pedal with the drag of the engine chain and clutch but I carry tools so I can remove the chain. I run a bmx side pull front brake to assist the rear coaster, 96mm reach will work with 2.125 tires.
Your results may not be the same,Greg
