the bigger the hole means a biger jet. ur low spead jet is located next 2 ur main jet. i would take out the one thats in there and compair size and numbers on it. u may need a magnifying glass to see the numbers

i think i have tried that but not sure. have tried so many yhings. i will try that and see what happens thanks

Thanks,,, but I forgot to add that I had yamaha do the leak test and it passed with flying colors. I did the compression test and it was within 2 pounds of each other,,

I have a 98 banshee,, I have shaved head, full procircuit exhaust system, mild port and polish, bored 60 over, 4mm long rod stroker crank, boysen power reeds. All of these items are brand new. I have a pair of used 28mm keihin pwk dslide carbs. The right bank was smoking more so I swaped sides with the carbs. And the right bank still smokes more than the left. The left plug is a light chocolate brown, and dry. The right bank that smokes alot is black and wet. I have run out of any ideas to try. Any help is greatly appreciated........
