I am only using E5 fuel, although it can be a pain to find. The tank was running low and I did put an additive into the fuel tank, but I don’t think it mixed very well.

Maybe the high ethanol content in the additive was sat at the top of the fuel, and then got put into the system in a high concentration all at once?

I have filled the bike up fully with E5 fuel, so I will update if the problem occurs again tomorrow. I won’t add any additive too.

I do have a slight exhaust leak, so maybe that might be affecting how the valves work. Thanks for the tip though, if the problem still occurs then I’ll post another comment and try to get a video of the issue.
