cheapest place to order/purchase #40 chain and rear sprocket?

Well, I did not see 50mph in that video, you can gear for acceleration or top speed, not both.

Cool, do it up!

When I did mine, it required some re-gearing.

Wish ya the best of luck!

Look at this chart to see the roller width difference of the #40 chain, it's 1/16" wider than the #41 and #420. Therefore, any of the 3 sizes sprockets can be used on #40 chains. However, #40 sprockets can only be used on #40 chains.

Got quite a bit done today. Just waiting on a chain and sprocket...and paint/primer to dry. Decided on a 54T rear. Should be a happy medium

That should do the trick, after some riding ifya find yourself wanting a bit more torque,
or it cannot reach top RPM's with your weigh/terrain, you can replace the torque converter sprocket with a 9 tooth
or even 8 for a bit more performance.

Made an exhaust from old bicycle handlebars from a thrift shop for $2. Made an air filter for the venturi since the cone filter would've hit my foot. Got my sprocket drilled, just need the center milled out now. Almost ready to rip!
