slides coming up too fast

[gsBert]

help!

my throttle is an on off switch with a bit of lag...

i think the slides are still raising to fast, im using gsxr slingshot carbs on a 1150 engine

opening the throttle pulls real hard on the pilot circuit, but as soon as the needle circuit engages, the engine bogs down for a second then revs up fast enough to spin the rear tire (and im not even talking full throttle here, just 1/4 to 1/2 open)

friends are guessing the slides are coming up too fast. one of the 2 slide holes in each carb is blocked with epoxy, should i decrease the diameter of the other hole? or do i have another problem?

[Billy Ricks]

Decreasing the diameter will likely just make the slides come up faster and stay higher. Remember it's vacuum pulling the slides up. If anything I'd try drilling a small hole in the epoxy sealed hole to see if it helps. You can always re-epoxy the holes if it doesn't help.

Go ahead and drill out the epoxy and try running it again. You can always re-epoxy if needed.

What size mains jets are you running.

[gsBert]

im running 140 mains.

ill drill the holes out and try it out tomorrow. ill let you know what it changed...
