As long as you have the holes drilled rather perfectly aligned to make installation go easier. I assume you have the other hardware sans sprocket?

i would recommend the middle front sprocket, which is usually 38 teeth. you will have to grind the center about 1/4'' larger to fit it over the hub, and most likely drill holes for the bolts. i've done this myself, it was a lot of work. i was trying to make a derailleur assembley so i could change gears without a jackshaft, but it was way too hard to make the chain move right. if anyone tries it you need to convert to regular bike chain first. (if your trying to make a derailleur on the left side of the wheel, the chain works fine for single speed)

simple spark plug wire upgrade. i was cruising the junkyard with a buddy looking for some vw parts, when I saw an ignition coil wire just sitting on the ground, at perfect length. turns out they are all over the place. when I went back up front, I asked the guy if he wanted a few bucks for it, when he told me I could have all the spark plug wires I could fit in my pocket. cut the other end off, screwed it on, and my bike runs 10 times better now.

I also found the spark wire from an industrial gas fired heater works great.

Place a small magnet inside the finger of a rubber glove,you can place nuts or bolts in some tight places.Sears sells a pair of magnet gloves for 25 bucks,make your own for nothing.HARLEYS DAD

A bit of newspaper inside a socket holds nuts in till you get them started, then it pulls right out when they are tight...

One good tip if you have a front fender. get rid of it so you dont eat the blacktop. My front fender broke loose and I went over the handle bars in a split second. did a belly flop at 20mph. and it hert. and i have road rash on my elbows and chest. so a good tip lose the front fender.
