Small copper line broke on 1993 gsxr 600 carbis it fixable

excessive gas in mixture- look at float levels and dirt in air passages in carbs

ok so

94 suzuki gsxr 750 carb

what do u want to know ????, why do people put silly lines on like this, not well formed, and incongruent, explain what ya want.

Have you turned the fuel tap on (If it has one)? As far as I can remember, there are only 2 lines ( Feed and Return) check that the one with the filter in it is going to the "fuel in" line on the carbs.

So long as gravity is in play with the fuel petcock it will work in any way.
Does fuel go through the line before the carbs?
If so then the floats or the float pin has a problem.
Check by removing the float bowl cover and check the bowl floats for movement.
A in line filter will help stop future problems,If you need to clean the needle jet try a guitar string or a piece of un-wound copper wire to clean it up.

There is a drain plug in the pan, it's the large bolt on the bottom of the engine. Remove it, and oil will flow out. You may also want to remove the oil cooler lines, if equipped, and replace the copper washers, if equipped.

Also remove the filter and replace it.

No not without modifying the base - very difficult

Hope this helps (if so please mark as very helpful)

try replacing the fuel filter.

Some bike did not come from the factory with a fuel filter. If it has one it would be under the fuel tank in the fuel line before the fuel pump or carbs.

check your copression if its fine take your pipes off and see if the problem still exsites

The choke valves on the carbs maybe jamed.Take out the carbs and clean them thoroughly.
