Helped a buddy retro a set of 95 gixxer 36mm carbs on his 86 this last week. He had some POS 34mm flat slides that were Way to small before. The bike is running low end better than it has since he bought it now. The only problem is at about 8,000 RPMS under wide open, it falls on its face and seems to be running out of gas. Are the jets to small? Thanks in advance for any help.
