Zepp: As you stated in your post, there is a lot of rotating mass in the Savage. The crankshaft is heavy, the balance shaft is heavy and spins at twice the engine speed, and the electrical rotor is heavy......as is the flywheel.
I installed a mid-weight flywheel initially, and then later I installed a super light flywheel - and I really have not noticed any "cons" to the switch. The "pros" are that I did cut my 0-60 time by 1/2 second with the mid weight flywheel as measured by my GPS speedometer.....I have not done a timed run with the super light one yet. The bike idles the same, starts just as easy, cruises the same - it appears that all the other spinning parts have plenty of rotating mass to keep the engine happy.
Speculation doesn't always prove to be accurate - thankfully DragBikeMike documented his experience.....and Armen made us some light pulleys for those of us who cannot build our own. The folks who have installed them all believe they work great!
Thanks, I dont disagre that much frome your opinion!
There is a lot of spining mass in our engin.
And mayby some Suzuki enginers put on a to heavy flywheel, to make it work for non experiancde drivers?
In anyway.. it still dont affect the inertia of the bike+driver that much.
Whats afect the inertia of a wehicel is weigt of both wehicel and driver.
And there is more to that.. one other importante thing how much clutch engagement time.
To that.. the engin need clutch to be to deliver power for forward drive/acceleration.. its basic mecanical/fysic understanding.
Then to next understanding.. to shift gear.. preferably the input and the outpout shaft should have similar turning rates.. its becuse of that we use the gas handel to eighter lower or rise the engin speed!
Any experianced rider dont ever think of this.. the juste do it.. by experiance!
And then to acceleration.. its about full clutch engagement on full gas handel!
Its easy to this on first gear.. then come some minor problems.. one need to shift to another gear.. and later to another.. it take seconds with no clutch engaged and gas handel lower to engage any next gear!
Summarise.. inertia/weight of moving parts of our engin dont do affect that much acelleration except clutch engage/full gas time.
In another solution, get rid of any helmets and other heavy biking clothings and one can probably get som better speed records.. dont do this at home.. its only stupid and dangerus!
I think I alredy sumarised.. but in case, dont drive naked on a bike, and dont even think about that a lighter flyweel gonna afect accelration on any bike.. except clutch time on a racing track.
