Acceleration problem

[jak900]

The problem occurs in a rapid acceleration when the throttle is opened quickly.
Carburetors are completely renovated and cleaned, any leaks are not any.
Gas was rapidly opened, the engine does not respond immediately, but tours will jerk and thinks for a moment, whether the mixture is too rich or lean, I think the mixture leaner works a little better?

Are the carbs synced? Do you have the stock airbox and filter?

synced is cheked and ok, airfilter is new and orginal.

[Lykkan]

Pinched fuel line?

[jak900]

No, line is ok.
My own idea is empty.

[Kreylyn]

I'm back at air/vacuum leaks caused by airbox boots not on right, drain line cap left off, or something along those lines. If that isn't it, then I would go back to checking carbs and their settings. Are the float heights right, jets and ports clean, etc...

IMPACT 3000-4000 rpm range is then functions normally.

That's your transition from the pilot circuit to the mains.
1. Do you have a jet kit installed?
2. Where are your A/F screws set

[jak900]

Slowly, turn the gas engine will accelerate normally.

1. No, orginal set
2. A/F screw is 2 turn out

Set the mixture screws to 2.5 turns out and see if that clears it up, other than that I'm at vacuum leak with Krey.

[Wild-Bill]

Set the A/F screws to 2.5 turns and see what you get. Check your float heights while you're at it. If that doesn't take care of the problem try shimming the needles with a Stainless Steel washer under each of the e-clips.

Don't try doing the needles at the same time as the A/F screws. One change at a time, Vacuum sync after each change and make sure you're putting the airbox on the carbs before installing them on the bike to make sure you don't have vacuum leaks.

buy a sync tool...best $100 you will ever spend. When you get good at it you can charge your friends a case per sync...at least thats what i do

I made a manometer (thread with info can be found via search) and it worked very well for $5 in parts

[gsx]

try using a nanometer after a case of beer lol

i'm just going by what i did, i use it almost every week. $100 for a tool is a necessary but unfortunate price to pay
