Jetting T-5 with Hush Kit

[oneskeeter]

I had everything jetted except pilots were a little rich . I had to put my hush kit on due to state regulations. It seem like my pilots went lean and my mains went rich. Does this make any sense?

I have porting done by Jim at Passion, noss head with 19 domes, boss intake, 33 pwk's, timing advanced 4 degrees, v-force 2 reeds, and i am runing 110 octane with motul at 40-1.

I have almost the same setup and when I put my hush kit on it did not change my jetting.....how is the weather and is it hotter or colder than when you first jetted....new gas or old gas...race gas does not seem to last very long in a gas tank in Colorado....just some thoughts..good luck..D

Sorry can't contribute on this subject as I don't run the Hush Kit, but... I did want to add that most race gas is more stable (longer lasting) than pump gas. The Trick 116 I run is stable in the barrel for at least the majority of a year.

on the toomey website they mention that the hush kit adds a little more power to the upper end of the rpm range of the pipe, although toomey recomends the same mains needles and pilots for their t5's with or without the hush kit.

 

 

the way i see it, more top end via exhaust mods means more pipe flow, so i would figure that adding the hush kit should require a step up in main jet size. toomey doesnt see it this way. i dont know what to say.

 

for what its worth ill tell you my jetting. while it may or may not be perfect, i havent blown her up yet so its gotta be reasonably close. i run the t5's with hush kit on a 100% stock bike. i have 3 holes cut into the airbox lid with a 2 inch hole saw and no snorkel.

 

my main is a 280, my STOCK needle is set on the second to last clip position from the sharp end. my pilots are 1 1/4 turns out and i run in 80-110 degree temps and 70-95% humidity at sea level.
