Fastassbanshee96 Posted June 16, 2013 Report Share Posted June 16, 2013 So I was working on trying to finish up putting my motor together today and just realized there are no windows in the pistons. It's a 485 cheetah, is that normal for these motors? Quote Link to comment Share on other sites More sharing options...
m671054 Posted June 16, 2013 Report Share Posted June 16, 2013 (edited) Builders cut in custom windows or drill holes to allow for better wrist pin lubrication. Ive been thinking about adding windows to mine. Edited June 16, 2013 by m671054 Quote Link to comment Share on other sites More sharing options...
Fastassbanshee96 Posted June 16, 2013 Author Report Share Posted June 16, 2013 So them the windows aren't a must.... Didn't know if they were for anything more than lubrication aid. Quote Link to comment Share on other sites More sharing options...
J-Madd Posted June 26, 2013 Report Share Posted June 26, 2013 They definitely don't hurt. I wouldn't worry about it if yours don't have them though. Quote Link to comment Share on other sites More sharing options...
