finally bought bike/carb question

[dj 96yzf750]

i just bought a 94 Suzuki rf600r,it has only 7k miles on it,exterior looks great but the bike idles fine and everything but when around 8000 rpm and higher the bike hesitates a lot, i put some sea foam in and mixed it around and ran the bike on choke for a while,should it do the trick?

Blocked main jets?

[dj 96yzf750]

yeah that is what i was just guessing,just hope the sea foam works a miracle

Do main jets really clog? I'd think the pilots would be clogged long befroe the mains. Can't say I've ever had to clean a main jet on any engine.

I'd be looking at ignition components.

Check your fuel filters and that gas flows good out of the petcocks as a cheap (0$) easy first step.

ok carbs where spotless,and my bike dosent have a fuel filter

More than likely the filter is in the tank attached to the petcock assembly.

If you haven't done it already new plugs are never a bad bet on a bike you just bought.

And also check the gas cap for a plugged air vent. In another words verify that you are getting enough fuel into the carbs to support higher RPM's.

Yeah, it sounds to me like it may be a fuel flow issue....

Easiest way to check is to pull the fuel line where it attaches to the carbs, stick the line in a fuel can & check the flow.

Check the petcock. Is it vacuum actuated? Does it have a "prime" position? If so, try running in that.



If that doesn't work, perhaps it's a float level issue?

ok so i pulled the fuel pump its working fine pulled carbs,there clean ,i am going to run through the fuel lines and petcock and vacuum lines today,

im with pete, check float levels.

How is your spark?

Are all the hoses/vents hooked up correctly? That causes issues sometimes. May have issues if float bowls need to be pressurized and a hose is dicsonnected or something.
