My '18 CRF250L has developed an issue where accelerating/cruising the power sputters regularly. Under harsh acceleration, the nose dives and sends me forwards. Seems to only happen when I have two bars of fuel, and when I refuel to 50%, the issue goes away. Had this happen with three refuels. I have a 12.5L Acerbis tank with a sock filter sitting at the top to catch debris when refuelling.
I'm travelling long term with the bike, so don't have my own space to work on it. I'm limited in what I can do.
Any thoughts?
