The engine has now started to run a bit uneven on all rpms, jumping turns. On idling the rpm also moves up and down a bit. Accelerating is okej, though.

It's very hot in Sweden right now, up to 30 degrees Celsius. The engine run more even before when colder outside and the idling was more steady.

Could the temperature have something to do with it? Didn't own the bike last summer, so I've never tested it in this hot summer weather before.

Or, could it be the ignition system that is a bit out of adjustment?

The moving up and down could be caused by an air leak. Will test this with some starter gas on the outside.

Will also buy some new sparkplugs, since I run them with the choke on before... I now use 7. Would it be an idea to use 8 during this hot weather?
