I changed the main and the pilot jets also I'm running 1/3 of the white spacer, it has a drain opening screw on the side and a drain pipe out the bottom of the bowl and yes it was doing it before the new jets.

Don't think it's a sticky slide, that would cause lag in throttle change.
As in hesitate to accel and fast idle, slowly coming down.

Not that a good carb clean wouldn't fix his problem.

What I believe is happening is that the fuel in the float bowl is "surging" forward with the combination of nose dive and braking. That changes the fuel level at the jets, and causes the mixture to be incorrect and the engine to die briefly. It is a problem common to carbureted engines with float bowl carburetors. There are some design features intended to minimize it, such as positioning the jets as near the center of the float bowl as possible, but the problem still exists.

I believe you are right on the money, that's exactly what's happening to my bike now I need to know how to fix or reduce the problem.

As a practical matter, there is no way to fix the problem. You can turn up the idle, which will leave the engine spinning faster and may give it time to recover from the stumble before it stalls. That's a work-around, not a fix. The only other solution is fuel injection. Or you could brake less violently to reduce the slosh.

ok you have the easy carb to check the fuel level on - pick up some clear gas proof tube that will fit over the carb drain - run the tube up above the carb say to the seat - open the drain screw level the bike and you can see how high up the float bowl the fuel goes before the float shuts it off - this fuel height is adjusted by very slight bending of the tab the float needle attaches to or even the float arms if your real careful - but first see where the level is now - so I assume you replaced the carb bowl screws with stainless allen head to make the drop'n of the bowl easy - when I get back to the house I'll gather up the shop manual that tells us the expected float/fuel height.

Just drain the bowl, turn to PRI, start her up and run her. Thats what I did after jetting. Anyways, watch my bike not start when spring comes around lol.

Your spring????? ..... you mean June Grin

-----------------------------------------------------------------------

The surge theroy makes a bit of sense since the pilot (low speed) jet is forward of the center of the carb....... in other words.... Off the throttle and it gets a squirt of gas when it's not ready for it.... and a little higher Idel would give you a touch more air to absord the extra gas.....

I had to replace it once because the engine was dying in hard right turns. Charon is right, I believe.

Lol. yeah we ususally start getting the teepee tents out at the end of march after the last snowfall. Thats when the igloos start melting lol. If the snow banks on the side of the roads and peoples front lawns are only 4 ft high as opposed to 15 ft, people usually start riding. Grin
