So what happen to carbs? I finally got a chance to look at my bike to try and richen it up a little and well what happen? I've been away from bikes for a little over ten years but all my bikes had the adjustments on the out side. I'm guessing I'll have to take the carb off to do what I need?

 

I'm just curious...what bikes did you have that had all the adjustments on the outside? An idle/low speed mixture screw isn't unusual to be externally accessible, but most elements that control mid to WOT require some internal work. I guess there are and have been some aftermarket carbs with some external or at least very easily accessed tuning features, but I thought most OEM carbs have generally required some disassembly. I do remember some OEM carbs that I've had that had a removeable main jet access hole in the bottom of the float bowl, but on a single where you can rotate the carb in the intake manifold, this may not be a big deal. You can disconnect the throttle cables and vent/fuel lines on the carb. Then you remove the throttle cable holder on the carb with one screw. This allows you to tilt the carb and access the float bowl and/or rotate it to get the top off. I did this yesterday to install a new Kouba fuel screw and a different pilot jet.

 

my dirt bikes with mikuni carbs all had air and fuel screws outside the. ???

 

there also probably pumpers. diffrent bike with diffrent carb = diffrent set up. technically, in states like california, its illegal to change the carb setting or add a pipe for th 09's (cat coverter to pass smog) on a street legal vechical. do to this they make it not to easy to change settings, fyi thats why the fuel screw has a cap over from the factory. what they dont see wont hurt them though.
