Help with sprocket hub

[cardsfan527]

Hey guys, I am working on my first build. It is an electric cart, and I have a question about sprocket hubs. My motor uses the 8mm chain size, so I picked this sprocket for my 1" live axle: (http://tncscooters.com/index.php?route=product/product&path=63_92&product_id=470). My problem is, I am having a very hard time trying to find a hub with the correct bolt pattern to attach this sprocket to my axle. So I was wondering if anyone could give me some good places to look for one, as I have already searched mfg supply, bmi karts, and several electric scooter sites. If not, is it OK to drill seperate mounting holes into my sprocket?


Thanks for any help!

As long as you can get the holes properly centered, there's no reason why not to drill. I've done it- just triple-check your alignment before drilling.
