The heavier flywheel means higher system inertial which reduces shocks to the motor and tends to balance and smooth things out. When you have a heavier flywheel, you increase the resistance to changes in the motor's rotational rate. This can be a good thing if you want to increase the durability of your motor and keep rapid changes in rotational momentum (aka shock and Jerk) from trying to stop the motor. The shock and "jerk" loads apply instantaneous high pressure spikes to the motor components and the pressure fed bearings, and these loads can cause the oil film in the pressure fed bearings to be thinned dramatically or squeezed out.
Hmmm.... that may help explain why there are no 30 year old Honduh engines left- low mass flywheels, marginally sized bearing and wear surfaces resulting in high wear and high shock loads to the system... (IMG:style_emoticons/default/idea.gif) Sorry Jake, it's the engineer nerd in me.... |

(IMG:style_emoticons/default/idea.gif) Sorry Jake, it's the engineer nerd in me.... You must be referring to an old series of Hondas that I'm not familiar with. the D-series and B-series honda engines I've seen have been very reliable, and have pretty damn heavy flywheels. |
