well it needs air, spark and fuel. I normally start with what's easy to check. air, just check the filter isn't clogged to shit. spark will be hard because it only happens at 8k but still runs. fuel you can change the filter but I don't believe they have test ports so you can put a gauge on it.




another idea, does your bike have the valve in the exhaust still, maybe that isn't opening when it should. most open around that rshared_pm. that is if honda even has one.
