You might want to try installing Dial-A-Jet. This is an alternative to rejetting your carbs, and it can be done by non-wrench turners. The only problem is that with the 'T' space is tight. I just put them on my bike last week to go with Jardine Rumblers. I now get better gas mileage and the bike runs great. You can get them at Wings Things (www.wingthings-texas.com/), part number DJ-107. For all you wrench turners, I am not trying to add fuel to the rejet vs. dial-a-jet debate here. All I am saying is that the Dial-A-Jet worked for me......
