'86-'87 GSXR750 Oil Cooled Fours with Mikuni BST31SS and BST34SS CV Flat-Slide Carbs
This is the first generation, for the US, of the GSXR750 with BST31SS carbs in '86 and BST34SS in '87. An entirely new design for Suzuki street bikes and routinely mixed up with incorrect parts, bad tuning and parts from other models that used the BST carbs like Katana 1100's.
Starting in '71 Suzuki started year coding bikes in the last letter used in the name. You may see this code on your bikes paperwork or in a parts list or catalog. I leave this off as it is redundant if you are showing the year anyway. There is a chart below to find your year code.
Below is a set of '86 GSXR750 28A00 carbs. These carbs take a lot of care to do them correctly. I have rebuilt a few of these and most had many pitfalls involved with the job. They also have very fragile floats and lock-tite on some screws that will ruin your day if not dealt with correctly.
