Default Re: Why didn't my bike go uphill with a 66/80cc cruiser?

Remember your power is in high RPMs not low. So you need to be in the upper RPMs (going fast) when you begin climbing the hills. Your engine will not be able to climb its own RPMs from the lower range. There are steep hills in my area and my bike has no problems when I'm going fast/high RPM, but when RPMs are low, it won't climb even small hills. If you are worried about overheating, check your spark plug. If it is oily then you should be good to throttle up.
