Removed my smog parts and jetted my carb with 38/125. Added a battery tender plug and after the test ride, just had to idle it down just a tad. No other modifications needed(and otherwise, bike is stock). Smog removal is straight forward, no instructions needed. Only thing that I was curious about was my kit came with two washer for the needle. I just installed one.
Don't really notice a difference in the way the bike performs, other than it seems to run out a little smoother down low and possibly holds 65 mph better than before, time will tell. I'm just happy to have that cleaned up look to the motor now.
