thx Kev
 

thank you for your superb mod... some1 said its the best thing that i did to my bike and i agree with that..
first the mods came with post (it took a bit longer than expected, waiting was the hardest part)... but due to Kev's superior shipping skills :smilies0948: they were in pristine condition...
following instructions and fitting o2 and fuel mod was easy..
and the result is awesome.. The Z is now smooth and slick as a ....:lovers[1]:

Thx a lot Kev and XT660.com

Thanks for your feedback & patience, I would say the mod must have been caught up in customs.
