Bit upset because I purchased an xt660.com sticker, paid, receipt & emailed to order but nothing for far too long now

Installed the Fuel Mod & O2 Controller perfectly, nice and neat, K&N in, snorkel out, set to 2 to 3 o clock and still surging low down, will keep tweaking but wondering if any suggestions on a better clock position on the resistor,

cheers & where's my sticker!

Fitting the Fuel mod as per the instructions + the O2 controller will correct the lean A/F ratio in the closed & open loops.

If your bike still show signs of surging it is unlikely to be A/F ratio related & would need to look at a few other things that make these bikes surge on the mechanical side. The biggest thing that makes the 660 surge is the rear sprocket damper rubbers that have free play in the rubbers.

My good friend, please send me a pm with your address and I will resend the sticker, also let me know what colour

I send them all as soon as I receive the order and sometimes in very rare cases these can get lost in the post, not my fault but if you let me know I have no problem in issuing a replacement. contact me now by pm. Cheers.
