Suzuki GSX1100 ES Another quick carb question

[Neil-IOM]

Hi folks, Its eaten nearly a gallon of fuel today on the bench.

Carbs have been cleaned in the ultrasonic and all passageways are clear, float heights set to 23mm.

Valve clearances checked and reset to 4 thou cold. Compression checks all give 130 psi give or take a nadgers with no significant improvement with a squirt of oil down the bore.

Carbs balanced on the gauges pretty much bang on.

Still running a little cooler on number two using the spitty finger test on the downpipe and it just doesnt respond to throttle as youd expect.

Running open carbs at the moment with no filters, i do have a set on the way from SPS, and an open 4 into 1 exhaust

Pilot air jet  160

Pilot jet 47.5

Main jet 152.5

Now before my time the carbs had the air corrector jets fitted in the back of the carbs.

So the way im thinking is to go back to standard carb setup and give that a go, So HERE IS THE QUESTION,  Can you just remove the corrector jets from the back of the carbs and return main jet back to standard size 112.5 and the pilot jet 45?

I ve got the front half of the stadard airbox but would need to source the rear half. 

Many thanks

If you're going to re-fit the stock airbox, then going back to stock carb settings should work fine. If you are going to remain airbox-free, the easiest way to get it running well is with an air corrector kit. Losing the air corrector kit with no airbox and you will face an uphill battle to get it running well. Personally, I would go Baxter Basics and check the ignition, plugs, float heights, fit gauze filters and then check to see if there are any air leaks where there shouldn't be and check the carb balance again. Your jetting is very similar to mine (no airbox, air correctors fitted) and your symptoms sound a bit like out of balance carbs to me. If all this fails then I'd be opening up the carbs to check for wear somewhere or something like problems with one or more diaphrams, leaking seals  on the butterfly shafts.
