i noticed no one is mentioning the leak jet??? are you guys having problems with the stumble off idle when you stab the throttle?
louisville, KY
stock filter, no lid
HMF slip on
170 main
NDSR needle #3 down
45 pilot
2 out on the feul screw
30 leak jet
raised the idle just a hair from what would sound normal. it doesnt scream, but its a little more than a slow chug like you would hear on a 400ex
very slight stumble off the bottom when stabbing the throttle from nothing to full, but a 25 leak jet should fix it.
Planning a comeback...
BRADLY 300: I DONT HAVE A PROBLEM WITH A STUMBLE WHEN I STAB THE THROTTLE, IT WAS JUST @ 3/4 TO WOT, IT SEEMED TO HAVE MORE TOP END @ 3/4 THROTTLE THEN IT DID @ WOT. I PUT A 175 MAIN AND PLAYED WITH FUEL SCREW, THIS CLEANED UP MY PROBLEM @ WOT. QUESTION- IF I PUT A 45 PILOT IN WOULD I NEED TO PUT A 178 MAIN JET FOR MORE FUEL TO MATCH UP WITH THE MORE AIR? I THINK SO BUT NOT TO SURE. MORE FUEL & MORE AIR = MORE POWER?

I changed the main jet to a 160 and took the air box lid off. Runs great!

The answer is yes you should change your jetting, take your air box lid off and see how it runs.Originally posted by yfzrider310
