Hi. Start off by saying I know very little about the bike I just bought. It runs great and last time I took it out it was running up to 50 or more kms. Then I put some high end 91 grade gas in it, and started to experience problems. Fires up first pull, but only runs for a bit. I put a different hose on to bypass the pinwheel, that is not the problem. Gas flow to carb is clear. But I can see that the gas is not being sucked into the carb, it stays in the hose. I also noticed that alittle gas was forced out the top, also leading me to believe its a vacuum issue. Before I start taking the carb off, I decided to ask the more experience user here.
So I wait for advice. Please any advice would be appreciated.
