Bike has had an issue with high rpms for awhile. Did a dyno run and it put 82 to the wheel. What they didnt know is that it wont rev higher than 13k at wot. If they would have let off the throttle a hair it would have revved all the way to redline. Without knowing this, the tech told me without skipping a beat that it was the plugs. What do you guys think? Its a 2005 with only a yoshi rs5 slip on. What should I be making? Should I change the plugs regardless to see if it helps cause I know its a pain in the ass to change them.
