On a stock suspention is their any way to get the edge over the next guy for the drags ?

Thanks Tpsycho

 

Oh yeah....setup in flat drags is key. I run mine with the fronts all the way down. According to what size swingarm and the tires/gearing as to what setting the rear shock needs to be adjusted.

 

I am running 15/43 gearing from sidewinder I have not purchased my new rear paddles yet I plan on running 22 inch 8 or 9 paddle haulers with a stock swingarm.

Also am having hubs lightened and thinking about lightening the flywheel but a little woried that it might hurt me on the hill

 

Did you ever get your bike dialed in to run the flat drags?

 

Ya it is doing great I am able to come out of the hole in second with 22 Inch 8 paddle haulers and grab 3rd and cary the wheels off the ground the whole way and not wheelie over then hit the nos in 4 th all with a stock swing arm

 

Why would lightening the flywheel hurt you on the hill?

 

I have been told that the weight of the rotating flywheel keeps the anershia going and you wont bog down at the top of the hill ? I lightened mine up and it runs great. No issues with it bogging at all and it revs to the moon

 

Sorry, apparently Choose went and brought a bunch of old threads to the front of the line. I didn't check the date. I believe that whole torque loss theory to be a myth regarding lightened flywheels in quads. The only time I can see a torque loss is that you have less inertia on deceleration to keep the rpms up. If we were talking about farm tractors from the 1930's I would agree that once the motor got the flywheel up to speed, it would smooth out the power and aid the torque in pulling through the uneven resistance of plowing through soil. Those were probably 50 to 100 lb flywheels though.

We are racing and duning bikes with something like 7 lb flywheels. If reducing the flywheel weight reduces load or resistance on the combustion's ability to turn the crank, we should see at minimum an improvement in the torque's ability to hold the power curve and quicker revving.

If lightening the flywheel reduced torque then increasing the flywheel's weight could increase torque, If this were true we could invent all kinds of configurations like flywheel powered cars with briggs & Stratton pull cord engines.

Obviously I jest but the bottom line is if a flywheel could produce more inertia than the torque it spends to turn itself, perpetual motion would have already been achieved.

Sorry about the rambling monologue guys. I learn while I write.
