Good ... now bend over and change jets and test.

Unless you have access to a dyno and a lot of money ... at least to me.

Nothing replaces a dyno, but is it going to be happy?

I have a 140 here at 2k meters over sea level on an r80. different bike. Don't go too much by what others do. If you think you are going too rich or too lean on full throttle test accordingly.

Go fast, pull clutch in and kill engine, coast to a stop, pull the plugs and read.
and the jump from 145 to 180 is huge ... you would be blowing smoke everywhere if it was too rich.
