Recommended Posts

I jetted my T5 pipes w/2 into 1 Uni Filter/Outerwear per Toomey's recommendations:

 

280 mains at sea level

270 mains > 2500 ft

25 pilots

Needle Clip 4th down from grooved end of needle.

Airscrew at approx. 1.5 turns out from full in.

ok i just ran my bike with 320 mains and 27.5 pilots its run amazing mid range and top end but might have been rich ,but the bottom end bogs right off the go and adjusting the air screw didnt seem to do much for the bog , and when i pull the choke it dies so what should i do go bigger on the piolts , or smaller on the main jets, run a 50:1 mix or do all three ???? not really sure but your help would be great

ok i think im getting some where now im going to put the stock jet back in ,i already tried the needle at the lowest point and my fastest idle is after 2.5 turns out and its better but a slight hesitation still so the stock jet should do the trick .i just found out 50;1 is richer than 40;1 in fuel to air mixture

Try the 280 mains and the smaller pilot jet, like the toomey size. Should get you very close. You should be at 1.5 turns out on air sscrew as your initial setting. Then If that runs Ok, get rid of any mid range issues with small changes in the needle clip.

 

idle to 1/4 throttle = pilot jet

 

mid range = needle clip

 

top end/ full throttle = main jet

 

Only make one change at a time. 32 to 40:1 seems to be the best mix range.

ok so i finally got my jetting right in my carbs its was the needle jet i had it 2nd from the top when it should have been in the middle like it comes stock and it runs good bottom to top end so now all i have to do is change my pilot to a 27.5 or a 30 cause it run best with the air screw half turn out

the needle jet being off by just one spot made my bike run like shit on the bottom end no power till i got some rpms going
