Hey guys, I've got a 95 Yamaha Fx1 with lots of modifications, but I'm having trouble with it cutting out power under full throttle. I've determined I need to richen the carb, which is a blackjack 46mm. I've read around online that adjusting the two mixture screws will take care of the job, but other people say I'll need to rejet it. They say that fiddling around with the adjustment screws while the ski is idling will only adjust the mixture during idle, and that in order to change the mixture ratio under throttle, (which is where my problem is occurring) requires replacing the jets. If anybody could provide some feedback, I'd appreciate it.
