Hi everyone,
This thread is to follow up my original thread, "Pod Filter Tuning Question". I have a 78 GS550, which I recently modified the cradle to and installed a rebuilt 82 GSX 750 motor. Due to space concerns, I am installing some rare Mikuni TM33 accelerator pump stytle carbs that I traded for on Craigslist. I was having success tuning for full accel and idle, but couldn't tune it past a flat area between above idle and 2500 rpm. I wondered aloud if the CV Dynojet kits suply a smaller air jet to correct that scenario with pod filters. After learning on this site that they do, indeed lean the air jet for a richer mixgture. I set out to mimick that. My air jets were already 0.5mm, so, knowing I could replace them, filled my existing ones with solder, since no lower ID can be attained. I had previously attempted setting the float level to a lower height, but reset it to where I found it. I am reporting that these mods have got me as close to correct fueling as it has has been yet! I am only going to bring the floats to the 14mm height, but measured as Bass Cliff's stepped float height tutorial shows to hopefully eliminate the momentarty stumble if I open the throttle too fast. Otherwise, I'll lower the jet needles. If the needles don't help, I'll change the main jet size. Thanks for the welcome, and for letting me bounce this off you folks! It is appreciated.
