What did you do to your quad today?

[lbjamm]

The a/f screw and the needle control different throttle ranges. The screw won't compensate for the needle setting. Also, raising the needle makes it richer not leaner.

so true

Ok i know nothing about how to tune a carb without changing jets. Thats why my pit bike with a 125cc motor and a 15mm carb ran extremely well for being way under- carb'd when the motor calls for a 22mm carb.

 

[lbjamm]

I'm not saying you don't know how to tune a carb, I said your post was incorrect.

 

[THORrider05]

Please explain how I am incorrect. I raised the needle (to richen) because of it running lean.

Mixture screw and needle are two different circuits.
The mixture screw adjusts the fuel/air through the pilot.
The needle adjusts the amount of fuel that flows through the main jet.
Which are circuits that effect two different throttle ranges.
But hell I'm sure you already know this.
Just run it, who cares!

That's not what you said. You said you turned the a/f screw out (which makes it richer) to compensate for raising the needle (which also makes it richer) so that it wouldn't run lean from raising the needle. Which as I and Sparky both explained are two different circuits.

 

[THORrider05]

I know exactly what i did. My reason for raising the needle and turning the a/f screw out is to richen everything evenly. Why would you just adjust one and not the other?? Maybe your quads run differently in the mountains than my desert terrain. I have always adjusted carbs this way and they have always performed better than stock settings or just adjusting one and not both.

 

[lbjamm]

Why would you just adjust one and not the other??

Because they are different circuits. But whatever.

 

[THORrider05]

Yes they control two different functions and there for I am getting the most out of what I have by adjusting everything without re-jetting.

 

[THORrider05]

By the way I rode the quad with these adjustments and it runs alot better than before.

Installed the Dynatek CDI!!!

 

[Rockgrenade]

Upper A Arms on the 00. Finished the small trailer build.

 

[liftedhigh]

Spent about 10 hours on the trails today. Got to fix the clutch cover leak tomorrow.

 

[buzzy613]

i havent done any thing but think lol

 

[87warrior917]

Finally started and rode my piece after 4 months of neglect

 

[YAMAHAULER]

Rode #5 for the last time on trails till May
And the connecting rod bearing finally gave way on the boys 01 motor that we just replaced the jug and piston on3 days ago!

Well that sucks Ed. Guess you better hurry up getting your 357 together, so you got two running quads!!

 

[1998yamahawarrior]

Oh and on my own stuff got the Yoshi mounting figured out and stuff bought to mod it. Have to lengthen the mid pipe about 3" for it to clear everything and make a bracket for mounting the silencer. Probably being doing the welding tomorrow at work with the Lincoln MIG welder, so I can make sure its a good penetrating weld and semi smooth. Some times my little flux core welder just dont cut it when I want something to look pretty!!! LOL

Just need head gasket clutch cover gasket and stator side gasket and the 357 will be done and ready for #5 and be 5% away from going up for ELITE status!
