So, I'm planning on changing the exhaust on my valkyrie which has been sitting for a while. I'm currently taking the carbs apart as they're gummed up (from sitting). I was wondering if I should replace the new jets with higher flow jets (and if so, what size) to compensate for the new exhaust that will be installed, as I'd rather my engine not overheat from an improper fuel to air ratio. Any suggestions are welcome, thanks...
