http://www.allthingsmoto.com/forums/ If you have a post that is general in nature or applies to all Thumpers, this is the place! en Sat, 21 Nov 2009 02:38:28 GMT vBulletin 60 http://www.allthingsmoto.com/forums/images/misc/rss.jpg http://www.allthingsmoto.com/forums/ http://www.allthingsmoto.com/forums/f-63/master-list-motorcycle-valve-clearance-spec-47667/ Fri, 20 Nov 2009 10:59:10 GMT I have been wanting to compile a list of valve clearance specs for a long time, but I never remember to do it, until I'm no where near a computer.

The idea is to get as many years/bikes valve specifications as possible and post them so we have a central place to look for them. It will also really help those without manuals.

If you can post both the Inches and Millimeters that would be fantastic since one measurement might be easier for some to use than the other.

The ones I know... and please, if you can confirm other years are the same (if I couldn't confirm, I did not include the year), I will adjust the years so they match, or simply add it to your post.
