DB30S Doodlebug - How many teeth on the Stock Sprocket

[garycolwill]

Hello,

I'm building a DB30S Doodlebug and am wondering if the sprocket is stock on the rear wheel I bought with the minibike. The wheel is stock, and the sprocket has 75 teeth. Is that right? And, if using a Harbor Freight 212 and a 12 tooth clutch, will this work?

Thanks!

Never mind - I googled gear ratio and found that a 14.5 inch diameter tire with 75 tooth sprocket and 14 teeth on the clutch will give 29 mph top speed. I don't think I'll go that fast, but just trying to avoid uncontrollable wheelies.
