Not sure how reliable these numbers are.

I've removed the rubber snorkel several years ago. The effect will be that you have lean running Savage (try riding without the side-cover of the filterbox, that has the same effect). After removal of this rubber snorkel I enlarged the mainjet to a 165. It ran great, great torke, great sound.
A few years later I drilled 4 holes in the exhaust of 6 mm each. And I enlarged the main jet again till 170. A year ago I had to take the cilinderhead off and I flowed the in-letport. Now I'm driving with a 172,5 mainjet but the carb needs to be rejetted by a professional. And I need a new exhaust (The one I've now is kind of rusty...) so when I've changed the exhaust I'm going to a tuner for a better jetting off the carb.
The top speed didn't increase much, but the torque is much better. The tuner will make a dynojet-run which I can post here.
But I'm still saving some euro's...
At this moment the bike is running very lean with a little throttle and probaly much to rich at full throttle. So I really have to get this bike rejetted by a prof although it is riding fine.
