You could hardly do any better than to ask Matt about a base setting for the MC18 with TYGA pipes.

Matt hails from southern England so appreciates the climate here, and I'm sure will give you a starting point on the jetting.

Don't expect him to commit to a specific jet size front/rear though!

Personally, if the bike is running well/clean and currently making good power, I'd fit the pipes, do a plug chop and take it from there. In our climate a 2 size increase in MJ usually covers a pipe swap from stock to race.
