          At sea level 130 performed well in my Karizma when it had stock carb, stock exhaust, with stock airfilter box with UNI panel filter inside. 135 was a bit rich, 132 would've been good in my case. If you're much above sealevel 130 would do fine.

          I had to import mine from jetsrus.com

                  the bike will feel lean only at higher throttle openings so main jet change is all it needs.
