Anyone have a 16T 15mm wide 5m HTD motor pulley with a 8mm bore they would be willing to sell me? Or a recommended place to get one?
I was planning on using the one from the brushed motor from my donor zboard but the bore is bigger than 8mm, possibly 10 or 12mm so it wont work 
I found a 17T but no 16T https://shop.sdp-si.com/catalog/?cid=p346&filter=a0:2:5%20mm%20(HTD);a27:2:15.00;a32:2:8.00
Thanks. ill give that a try 
if you’re good with a drill you could buy a 16T 6mm bore pulley and drill it up to 8mm
i might still try that will the pulley i have, as the drive shaft is stuck in there super tight so i could bore that out.
I tried doing that on a cheap drill press and ended up with a super wobbly ass bore. Things I need

Don’t know if you did this, but for a more precision hole you should drill under size then use a reamer to finish the hole. If you already have a hole close to 8mm, then just use reamers. A good set of reamers won’t be cheap though. http://www.amazon.com/Accusize-Metric-mm-13-0-Chucking-5500-SB00/dp/B00RW6ZN66/ref=sr_1_1?s=industrial&ie=UTF8&qid=1464483797&sr=1-1&keywords=reamer+set+metric
