DYnoJet kit for 85 GSX750S (pop up)

[ddnova]

I have an 85 (86 actually) GSX750S Pop up headlight Katana with BS32ss mikuni's (32mm stock) on the bike. I have a K&N filter with a Kerker 4:1 pipe and am looking at a dynojet kit for it. Does anyone know thw proper K&N kit # as they vary depending on site and I am confused. Also has anyone done this to their 82-85 GS750 and if so did you notice a difference in performance?
Any help is greatly appreciated, Thank you
Darren

This is essentially the same motor as the 83 GS750 or the 85 GS700. A jet kit for either of those will work for you. That should widen your search CONSIDERABLY! Ray.

Because you have both an aftermarket pipe and a K&N inlet filter, I'd recommend a Stage III kit. You need the kit #3315, found here: http://www.dynojet.com/jetkits/motorcycle/suzuki.aspx .

Be careful, there have been Chinese-made counterfeit Dynojet kits popping up on the iternet. Here's the warning:

I recently installed a Stage 1 kit on my completely stock GS700ES (same engine as in your Katana, but with a shorter stroke), and now wish I'd done it twenty years ago. Quicker warm up, less choke at start up, slightly improved lower and upper end power, drastically improved mid-range power.
