    Where can I buy a #38 pilot jet. Is there a website you can point me to? My bike still has the stock #35 installed. I've got the pilot screw (fuel screw) 3 turns out, but really need to bump the pilot jet up a size.

    I went with a UNI filter, removed the snorkel and cut a couple large holes in the top of the air box. The bikes getting a lot more air now.

    do you still have stock main jet? 98? be sure to check your plug too. you might get a couple main jets to play with 100,102.5,105 see what works best!

    It has a 102.5 in it now. I will plug check it soon. I had no problem finding main jets (98 to 110). Right now, I need to find/install a #38 pilot jet. My local Honda dealer is 40 miles away. I'd rather buy it online if you know of a good website, please let me know.
