Greetings Mike,

To tune properly we have to make sure that the bike has power all over the RPM range. Not just at 100% Throttle.

Shredders comments notwithstanding, look at the power difference on the 75% throttle run at 6000RPM. WOW!

Or here is a graph for a F800GS RB 3 Application for example:

0-05-10-20-40-95 % Throttle. Tune For Power!

Here is what that map looks like as represented by the above .pdf:



Here is the map at 100% ONLY! See the difference:



Oy Vey, the 800 would suffer at anything below 90% Throttle.

This is a tech board Mike, you raise a good question... Don't apologize!

Ask more questions, raise more awareness!

Most of all enjoy the ride!

Do not go where the path may lead, go instead where there is no path and leave a trail.
