Nice, I am still looking to get a K24a2 if anyone knows where I can find one. I think Josh sold his or something. I was serious about buying it but not until May, I have the cash now so let me know if anyone knows where to get one.

Contact steve at Hmotorsonline.com
he gets them in occasionally and if he doesnt have one he can get you one.
they have alot more than whats just listed on the site.
