Big Bore 750 ring info
« on: May 04, 2012, 08:02:49 pm »
 I havent searched yet, but know some sizes of rings are hard to find. Found a nice set of Venolias, that may get me back into a big-bore 750 again if I can find rings.. they look useable.
 They are 71mm, and rings are as follows;
 Top Ring....o58 inch
 2nd Ring ....0583 inch
 Oil Ring ......0958 inch..3pce     Are these bastrds or common ?

 These pistons are actually fairly light, with rings, pin and one clip...240 grams..lighter than an Arais  836cc and these are 1000cc.
 Maybe I can put togeter an econo big-bore...if I can get rings..

I have some old Venolia's as well Frank, they come out of an RC kitted bike i own, when i spoke to the guy at Serco here in Australia {a couple of years ago} he said that he could get rings for them if i needed any.... Don't know from where but thats what he said anyway....
Not much help i know....
