just put a yoshi full exhaust on my rap
jetted the carb 160/165 as recommended by yamaha
it seems to run strong except for slight hesitation early on the throttle
is my jetting wrong?
also the head pipe turns blue right away is this normal?
i cant iimagine im to lean maybe to rich?

 

Did you adjust the air/fuel screws? Did you put the needles in a different clip position than stock? The blueing is normal for that type of pipe.

 

adjusted air/fuel screw 3 turns out on left carb
put clip in third groove
it runs strong in the middle and top just the bot that is prob

 

What about the screw on the right carb?

 

2 turns out on the right carb
followed recom from gytr jet kit
took it out this morning and it is loading up ( i think) on the low end
it does clear itself out when i get going
im i to rich? im afraid to lean it out without some good info

 

any suggestions???

 

my friend got a yoshi slip on, and if u nailed the gas it would kinda hesitate just for a tiny bit of a sec tho, then it was fine, and only if u really punched it, it was a slight hesitation. i heard something to do with valves was a possible problem.

 

i hope that isnt the case
i just adjusted them so i hope thats not a prob i caused

 

so i messed with air/fuel screw with no luck
still looking for some opinions

 

I can't believe you haven't recieved any more help than this so far. You've certainly been patient enough. [img]i/expressions/face-icon-small-smile.gif[/img]

You're jetting sounds good, I'm assuming you're below 3000' elevation. You should need to be 2 1/2 - 3 turns out on the air/fuel screws each side which is what you say your at. You say your needle is on the 3rd/middle groove which is good. I'd say try putting the needles one groove different at a time, either higher or lower until you've tried all positions. Keeping the needles on the same groove as the other each try. Also double check the diaphrams in the top of the carbs for tears and the carb boots themselves for tears etc. Do you run with the lid or no lid on the air box? Can you take it off and try without it? Hope you get it figured out.
