jcone Posted July 9, 2020 (edited) Hi , is there a manufacturer out there that makes a 520 pitch front sprocket for 17mm shaft. I’ve got a custom build going on and I’m trying to figure this out. it’s a Piranha 140 engine that’s why I thought I would post it in the pit bike section.

dirtbkr188 Posted July 9, 2020 (edited) THIS ONE might work for you My mistake, it's a 20mm OD, not 17mm Edited July 9, 2020 by dirtbkr188 Share this post Link to post Share on other sites

Affy Khan Posted December 7, 2020 I have this same problem too on my custom project any idea what to do?? Share this post Link to post Share on other sites
jcone Posted December 8, 2020 I cut the center out of the 420 and welded it to the center of the 520, it’s holding up just fine with 30hrs of ride time on my custom build. Share this post Link to post Share on other sites
