#9 has to be drilled out to get to #4. Dig through The Wolf's Bike Shop; just how far do you trust me? to get a better idea about what you have to do.

Is the cover air cut valve on the side of the carburetor supposed to set flush or have a slight gap

 

Thanks ChrisM, just what I was looking for.

#4 is the needle you need to adjust out, it's called the idle mixture screw, and turning it in clock-wise closes off air to lessen fuel, and turning it out counter-clockwise opens up more air to draw in more fuel, the needle adjust the pilot circuit for slow speeds and idle. To remove the plug drill a small hole in the plug being careful not to drill the needle underneath, then use a metal screw into te plug to get a good seat and then use pliers to get a good grip on the metal screw and yank the plug out to explose the needle underneath. Factory stock settings on that idle mixture screw needle is probably in the 1.25 turns out range, so you might need to turn it out more another half to full turn.

 

removing those baffles in the pipes caused the backpressure to the cylinders to be lowered and now it scavenges air/fuel mixture out of the cylinders before the exhaust valves close, so to compensate this the engine needs more fuel, thus the opening up of that idle mixture screw to allow more fuel

 

you might need to remove the carb or at least losen it from the intake boot and pull it out somewhat and twist the carb sideways so that you can get to drill the plug

 

Any harm running the bike with the choke on till I have the time this weekend to get to that pesky carb adjustment screw?

Only thing I can think of is you will run rich at the higher RPM. No harm, just lowers your MPG. Long tern may foul your plugs.

 

I'm having the same problem , I just bought this bike and it idles low and cuts out , the previous owner changed the pipes , the jets are stock , I live in a higher altitude so I thought it was the air / fuel mixture , but I don't know, any ideas ? thanx .

 

adjust the idle speed

 

Nobody answered where this pilot screw is located. I’m not taking the tank off and removing the carb to adjust it. Can it be done without all of that? Is it on the air cleaner side? Someone take a pic and point it out or something. I have gone to YouTube and every forum imaginable and nobody shows where this magical air fuel mixture screw is.

 

If you look at the diagram above, find the 4 follow the line at the top to the carburetor, it looks like a tube pointing down the screw is up inside the tube. I hate to be the bearer of bad news but every time I have had to adjust it I had to take the seat, instrument cluster, tank, air cleaner (cover, filter and backplate) off, remove the bar holding the carb and loosen the clamp on the manifold, carburetor side.
Then you can pivot the carburetor out towards you and see the screw.
I know some here have done it with angled screwdrivers or ones they modified but I never could, that or a shop.
