I have a 97 Kat 750. Full Yosh system (headers, 4-1) and three degree ignition advancer. When I got the jet kit, the instructions stated that if you are running a "street pipe" like the Zyclone that I have, DON'T change the jets (don't install the bigger ones that came with the kit, stick w/the stock ones) Per the instructions, I changed the needles, float level and reset mixture screws. The instructions say only change the jets if you are running a race pipe. But....I'm curious. The bike has great top-end now, but throttle response could be a bit snappier. The short answer, I know already "just change the jets and find out". Well, if you've never worked on a Katana before, you already know that to get at the carbs, you have to remove EVERYTHING FIRST. Windscreen, mirrors, signals, both fairings AND the tank, just to get at the carbs. If anyone has had any experience with this, I'd appreciate it. BTW, the new jets are one size bigger than stock. Thanks.
