Any modification to the way the bike breathes and exhales would be serious in terms of new jetting.

So id sugggest giving jetting a try...

Can the jetting change so much as to cause 60km difference with no changes to air input and exhaust? As I said earlier I have made NO changes to the bike since this restriction in revs started.

If it is jetting why would 1st and 2nd not be affected?


thanks,
