Needle Shim Mod Questions

Jordan310 · 02-19-2007, 05:54 AM

I have a question about the shim mod for the gz250.

I took my bike to my mechanic, and he re-jetted the carb, but when looking to do the shim adjustment, there was a groove where the clip sat.
He pointed out that the needles for jet-kits had grooves, and showed me some. The stock needle did not have additional grooves.

I have a 2007.

Any help / advice here?
