Motorcycle conversion ideas

[TurnNBurn]

Alright guys, need some advice. I'm about to begin mounting the motor, but I need to know what needs to be bought first. I need to make a custom bracket/frame to hold the motor in place to the motorcycle frame. Should I get the sprocket for the motor first and then the chain so I know how it'll fit in place? Or should I mount it and worry about sprocket and chain after?

Personally I would get the sprocket and chain, align them perfectly, then from that position make your engine mount. Since I can weld, that's how I would do it, then I would have perfect alignment. You could also slot the bracket to allow for adjustment, but if you are using a motorcycle chassis then it should already have a front to rear adjustment capability.

I can change the chain tension by moving the rear wheel forward or backward. I already have a website in mind that has the sprocket, but I have 2 questions before I purchase.

1: What size of sprocket should I get (number of teeth) for the motor? I'm looking at getting up to 65-70 MPH with this bike and wand a good gear ration to support that.

2: Can you even purchase chains with removable links anymore? I'm not seeing any for sale. Or maybe I'm just looking at the wrong vendors.

-edit-
I was able to do some more research finally and it seems a 4.5:1 ration is standard, but if you want faster acceleration and faster speeds, 8:1 is what people are using. So I think I'll look in the range of 6:1 or 6.5:1.

I'm posting more parts and parts sources so others know what to get and where to buy it.

Looking to start with a 16 tooth gear for the motor. I'm thinking of this one here.

For the wheel, I'm looking at an 80 tooth sprocket. I haven't done any measurements for the rear wheel yet, so I don't know the exact gear I'll get. I need to get the diameter of the bore first.

Alright guys. Sorry for the flood of triple posts. I need some help. I got the motor in and I've been trying to custom fabricate a very simple mounting plate. Does anyone know of a shop that sells generic mounting plates for the ME0913 motor? I'm looking for a generic plate that I can then weld or bolt onto my bike frame, so it doesn't need to be custom fit or anything. I find that at this point in the project I am lacking the proper tools to cut and drill all of the metals.

Alright guys. Got my welder and I'm about to mount the motor, but I've run into a problem finding the sprockets I need. I decided to go with a 6.5:1 ratio, meaning a 14 tooth sprocket on the motor and a 72 tooth sprocket on the wheel. However, I'm having trouble finding a vendor who sells 72 tooth sprockets.

Do anyone have any vendors in mind for 72 tooth (or maybe 128 tooth?) sprockets? I should mention that I have found some sites that sell 72 tooth, but they're like $80 a pop.

On to my second issue, the controller. Can you guys do me a favor and keep your eyes/ears out for a used controller? Maybe one from another project that has been abandoned? I'm looking for a reasonably priced controller that's below the $300 mark.
