Has anyone identified a source for replacement rings for the earlier Gen1 piston?
I've begun looking several times but without success.
Over on .net, in '08-'10, Xdragracer or Extreme sourced some "useable" Hastings rings for the 2008 and ups.
Looking at KLR service manual the top 2 rings are the same width for both pistons. (1.17-1.19mm)
Couldn't the expander ring be reused? That just leaves the oil rails.
Where they/he may have gone wrong was to uses Two 'Barrel-faced' top rings. Hasting #46835.
The second one needed/needs to be chisel faced or napier, what ever is the proper terminology.
2008-up Hastings Expander #48890 (.0578inch), TOO narrow for 2007-back.
2008 (Only, Maybe?) Hastings Oil Rails #48354 (.018inch)
Do I remember the 2009's were .020inch???
There may be a difference in oil rail 'depth' (old - new), due to type of expander.
Do you still have the 30+ Wyman Winn pistons?
