started working on these carbs today and I have a few problems here we go ,

here is some info first,
the nice village ppl replaced my vacuum petcock with a freeflow petcock
*IE pretty much gas 24/7* and replaced my exaust with a all most str pipes *no mufflers*,
cbr f2 600 93
and the problem

when starting the bike runs desent and I can get it to start very easy
the problem is while riding the bike under 5k or with our throttle the bike acts like its flooding * and excess gas on spark plugs-wet when I pulled them, would my free flow petcock be the problem since in theory its flooding the bowls when I let off throttle OR is it a jet problem since gas goes threw the jets and its just letting to much gas in- not enough..?

and lastly if the petcock is the problem since I don't have any vacuum lines where do they come off from..?

 

The petcock is not going to cause your bike to flood. The float valve controls the flow of fuel into the bowls so it doesn't matter what type of petcock you have.

Since you have a very free flowing exhaust, I'd think that some carburetor tuning is in order. To do it correctly you should see if you can get access to a dyno so they can check the air fuel mixture and let you know how rich or lean you're running throughout the RPM range. You'll need a Jet kit as well which will allow you to change to various sizes of jets as well as adjust the height of the main jet needle. It's challenging and time consuming to do. It's also hard to find anyone willing to do the work since carburetors are old school.

Good luck and I hope this helps.

 

so next question of the week :P, does the fuel air *** that's on the left hand side of the seat control the fuel/air for idle or all of the jets..?

 

The **** on the left side of the bike adjusts the stop position of the throttle butterfly. If it's backed too far out, the idle might be so low that they bike won't run or stay running. If it's too far in, you'll have a high idle like 1500 or 1800 RPM. It also may be difficult to start when cold because it's not drawing enough vacuum. This does nothing to effect the Air Fuel ratio or have an effect on any of the jets.

 

thought so, since I don't have any hard starting or high idle I wont mess with it
