gearing for kit on moped frame

[katch26]

so my employee's been building this frankenstein bike for quite some time and it looks like we'll have it running in the next week or so. I have some reservations on the gearing but it's hard to figure out ( with no motorized bicycle kit) experience. The bike is built on an AMF roadmaster frame with tomos 16" rims. I found a calculator, see attached, and it looks like it might work with the current gearing. So my question is, on a completely stock kit, will it have the guts to pull the gearing?
thanks.

what engine is he using and is that a ratio for a jack shaft?

It's the 66cc kit from boygoesfast. The 10:22 is just front and rear sprockets no jack shaft kit or anything.

you have to count the teeth on the gears on the clutch side, I think its 22 and 80, but I could be wrong. you have to add those gears to properly calculate the ratio though.

Oh ok I got those numbers from this thread

I had it almost right, but a little backwards, lol. I said 22 and 80, its actually 20 and 82.

The redline on the 66 cc motor is about 7000 rpm so that
will change your gearing a bit from your 6000 rpm
