Jetting advice

[rossi]

Found time to do a bit of tinkering and jet swapping this afternoon. Fortunately I have a km of 10% gradient twisty road at the end of the street so I am able to give the bike a pretty good run to test out the effects of any jetting changes with the engine under load. Going up on the main definitely made things worse with the bike struggling to pull until it hit the power band, much like it was at the weekend. #1 on the needle is also giving the best response.

For the moment then I can't do any more with the jetting as I am as lean as I can go without getting more brass. Since the plug looks spot on now, and my jetting is leaner than most of the settings in the database, I don't think that is necessary.

I'm back up the mountain at the weekend so I will see how it works then.

Next stop will be checking and correcting the squish.
