Donít trust the pipe
I like spark plug readings for tuning. Some tuners like the exhaust tip ring color for cruise speed setting, but motorcycle tuning speeds vary too much to put much trust in exhaust tip color. If you get a ghost white ring there you need to check for trouble. Those high altitude readings can be tricky. If she runs good and plug burns brown, no further action required. Watch and listen for detonation or ping. High altitude running with ethanol laced fuel is tricky because ethanol wants a richer tune and the absorbed moisture in the ethanol makes motor sound blubbery and rich but plug burn remains lean. You have to jet for plug color and you may find one cylinder likes a different jet number than other cylinder. Give it what it wants as if itís 2 separate motors. They donít have to share common jet number as long as your plug burns brown you are good to go.
A REAL MANS CREED
If it rolls, burns rubber, flies or shoots, runs on gasoline or gun powder, makes lots of noise, produces recoil or a
rooster tail----it's cool.
But if it uses a ball, a bat, racquet or club, or is played on a court or green by yuppies or liberals----it's a piece of
