...carburetor tuning is painstaking, time consuming...
..don't cut corners..learn all you can about what you're going to do, BEFORE you start...
:o
..PLUG CHOPS will be the key to success!!..

what are plug chops?

what are plug chops?
..plug chops are performed when tuning a carburetor..
..their purpose is to give you an indication of what your fuel / air ratio is, at any given throttle position..
..the reason the are so important to perform is, you could be running a "lean" mix..which could do some SERIOUS damage to your engine...
..NEVER RUN LEAN!!
..btw, Tutto..I read one of your posts where you said you had white smoke from your exhaust....
..what I found to be true, is that if you have a "rich" mixture, the smoke will be black...
peace

I second that! ;D

Hey guys, I didn't see the white smoke post, but that would usually indicate coolant getting to the combustion chamber.

..I think Tutto's smoke post was in the K&N thread...
..the Agility 50 is air-cooled...
-
If the smoke is white, I was always taught oil was leaking around the ring burning with the fuel. Black smoke is lean. 8)
-
..okay, let's all debate smoke coloring...I was running very rich...I had black smoke from my exhaust...decreased my jet size...the black smoke went away.....
..NEXT!!
;D :o

I have a 2-stroke, always blows a little blue smoke. If it doesn't I have issues! ;D

..that was always my knowledge..
.. Black = Rich..
....Blue = Oil..2 strokes are a fine example..
..White = Lean..or other issues...

Slinger- I would agree!

I've read in link from wordslinger a thing that I dont understand in my language ... maybe you could say in other way :-s :
"At the end of your full throttle run simultaneously push the kill button, chop the throttle and pull in the clutch."
what kill button ?
he refers at brake ?
-
I think that is in reference to doing a plug chop. You want to push the engine shut off switch while maintaining the throttle position until the engine completely shuts off.
-
so after I stop the engine he say to don't pull the throtle cable again until I remove the spark plug ?
-
Hold the throttle where it is until the engine is shut off. That way the plug will show what is happening at that throttle setting.
-
For example, if you are running a wide open throttle plug chop, don't release the throttle until after the engine stops completely.
-
...do you guys do your WOT chops while riding?
..or on th stand?
-
Been busy hows everyone, looks like you guys have it handled, I agree with the carb tuning it is awful still tweaking mine, but i am running more than 50 now on the flats still need to figure out an exact speed but keeping up with the cars passing with ease as well. I am loving it, up hill is still a battle but not nearly as bad as it was, but I will say this I am blowing all the scoots out of the water, I have had so many people asking me what the hell I had under her!!!
-
You're back, havent heard from you for a while, good to hear your scoot is going well.

..ain't that a blast?!
..dude, did you ever get that pipe?
-
...do you guys do your WOT chops while riding?
..or on th stand? Riding! The load on the engine makes all the difference.
-
..okay, that's what I thought...and i don't like throttling wide open on the stand for more than a second anyway...
-

As Zombie said, While riding! Gotta have load on the engine!

Didnt get the pipe, still working on the carb though, I keep messing with the jets, I am running rich now when i hit close to my top end my scoot slows me down still havent raised the needle yet just been enjoying the ride. I really hope to get this thing right but havent had much time to work on it I will keep updating, want to take her on a long trip, but want her running right first

...dn't know about that needle raising...i've tried it, but have always gotten better all-around response with it in the stock position...
..with a lil help from my friends, i've been able to tune it out with just the main and slow jets...
..but you do have a kit on dat bitch, so....... :-\
