Besides, I don't care what anyone says. Jestal is always right when it comes to anything engines.

City slicker.. they ain't called gangs.. theyze called 'Millitias' as in the Creston Militia. :comando: :trinibob: :comando: ...and, have you seen those new Harley UltraClassics?Jebus, Carver... just shoot the mutha and put it outta it's misery, make an insurance claim of a drive by (those gangs in Creston are vicious) and buy another Harley. Problem solved. :bleh:
Video please. B)I'm gonna go out front and buzz the neighborhood at 9K for a bit ........ it's work, but somebody's gotta do it.
I am going to print jestal's response out for the next LEO I meet, will store it right under the seat. Jestal, can I have your full set of credentials so that when I go to court... :biggrinsmiley:Frequent bursts of throttle, however, are best for keeping the chambers clean ......and most fun. Flog it, it needs it.
I hear that Yamaha is looking for a new technical writer, especially this kind of advice for it's customers. :yahoo:WOT and high RPM will usually keep the chambers pretty clean and the rings moving. High RPM alone doesn't do it so riding around in first gear at 9000 at part throttle or revving the engine in neutral is pretty pointless. The motor needs the chamber pressue, heat and extreme turbulence of WOT operation to really clean things up.
One thing common in high performance, compact combustion chambers (like the FJR) is dedicated squish areas..i.e...where the combustion chamber matches the piston shape and the piston comes very close to the cylinder head. So.....the take-away here is that high performance engines with a lot of squish do not like to be babied. They need to be exercised regularily at high RPM and WOT to keep carbon buildup at bay.
Some high RPM probably would, though. Frequent bursts of throttle, however, are best for keeping the chambers clean ......and most fun. Flog it, it needs it. One purposeful maneuver that is relatively safe and benign is to leave the trans in 2nd gear, hold full throttle as the engine runs up to high RPM then let off and let the engine decel or engine brake back to a reasonable RPM then whack it open again and run it...then engine brake down. Do this a dozen times or so. Cleans the chambers, moves the rings around on the piston (high RPM and light throttle will cause the rings to flutter and rotate on the pistons) to keep the ring grooves free and is an excellent way to load and unload the engine to effect breakin when new.
Reminds me of an old Bill Cosby comedy routine.I am going to print jestal's response out for the next LEO I meet, will store it right under the seat.
