Default Making port molds

Hello everyone, just wanted to share the info on my recent attempt at making a quick mold of the transfer ports on a 50cc cylinder. I know a lot of you guys port your cylinders as do I and with them being so small and in confined spaces taking measurements with tiny dividers and such is a huge pain and sometimes not accurate. I will post a link to the pictures and rundown on what I did if you want to look at it. The product is Composimold and it worked great for this application. Got it on ebay for around 20-30 bucks. Here is the link to the info and some pictures for anyone interested. http://bucketracing.blogspot.com/201...mposimold.html

Rad. Thanks for sharing. I'm still using off the shelf cylinders but if I ever get into tinkering I'll be sure to use this information.
