Default Re: engine gets LOUD at full throttle

The best way to mount the engine is with the rear mount seated to the angle of the seat tube then make adjustments to the front mount. The more contact you have at the rear mount the less likely you are to have problems. I like to install the rear mount till the engine barely slides up and down , then get where I want it above the pedal chain guard then measure and make a spacer for the front mount. Since most of the low end frames all have different seat tube angles all the front mount spacers I have made were slightly different.
Your results may not be the same,Greg
