Re: Yamaha bogging down under load but idles and runs at speed no problem?????

1. Contact the manufacturer and inquire as to what seals in the motor need to be replaced due to the ethanol

2. Sticky timing advance. If you don't have electronic timing, check your vacuum hose to the timing advance for leaks and/or check the smoothness/lubrication of the timing advance mechanism under the flywheel. If you do have electronic timing, buy a new/used one, try it out, take it back if it didn't fix it.
