I bought a 05 klx 125 from a friend who had the bike in his garage for a couple of years without draining the gas or adding stablizer. I drained the varnish from the tank and soaked the carburator in gas with the bowl off, I blew air through the jets and still can´t get the gas to flow through. Does anyone have any thing else I should be doing/using. I also have used carb. cleaner.
