Makes you cackle like a psycho

Comments On Dec 18, 2015:I went from running stock #98 to a #115 main jet on my 2007 honda recon and it made the best difference in the world in power, throttle response and torque. You too can bust out some sweet 12 o' clock wheelie ropes at 30mph with these jets in your PD series Keihin carb. NOTE: was not paid to say this but seriously, if you are having throttle response problems buy bigger jets. You'll like the way you look(while wheelie-ing), I guarantee it.
