Heard your cub ran well what about your 10 mill how did it do

[atcandbanshees]

Nobody call that guy to tune your bike that was a joke lol! I didn't get the 10mil done in time billet intake didn show up in time to bring the bike

Build a leak down kit ASAP. They're cheap and all the info is in the technical section.

My current set up on my ported 421. Aggressive port by HJR. 35 pwks, 152 main, 45 pilot, cel needle on 4th clip from the top. I have 19 cc domes, VF3 reeds and +7 timing. I started out with a 160 main and a 52 pilot and it did not run clean. It was clearly running rich and running hot. Make sure your carbs are synced and opening all the way. Check your intake boots and make sure there not cracked or have loose clamps. Check all the little stuff. I had my dyno tuned at Redline racing and It has ran great.

What compression are u at with those 19cc domes
