How light can a flywheel get? Bling and more bling
 

Flywheel

234g????? I bet it doesn't idle very well! :lol:

Hmmmmm........ ideal for the racer maybe but, not the road bike I think.

I've just been a very bad lad and spent a lot of money. :lol:

I am struggling with that exact item at the moment.
it has no marker for timing. but I have been told it does not matter.
well im just about to go out in the garage and find out

don't know about how light a fly wheel can be but i'm about to have a ali clutch assembley fitted on mi 900ss:bouncy:
any way was just wondering if i should/need to lightern the other side of the engine too?

Looks like we're all playing with those centripedal forces. I've just had a titanium clutch basket fitted.

Here's one on eBay:

Purchased one of those Alloy flywheels last year for my 955 Corse motor, by the time the starting gear was bolted to it it weighed about the same as the original Corse flywheel so will hopefully be OK.

Was there not a post from Shazzam all about flywheels????

Did he not sum up that bike manufacturers spend loads of hours getting these things right only for other people to think that they know best?????

That was my conclusion

And the majority consensus that replied was Shazzam knows a hell of a lot but he isn't always right....

Yeah yeah I know bolt of lightning is going to strike me down where I stand....:devil:

thats not what i concluded from the 'shazzam conclusion'

Just like the majority voted for the Labour party and according to another thread, theyre not right either :rolleye:

so has anyone got the insight as to wether i need to lightern the other side of the crank to keep it balanced?

I take that when Ducati design the bike they make an allowance for the magnetic load of the alternator when running with lights on and as such have added a bit of extra weight to the flywheel to stop you stalling it during night/day use with the lights on.
If the bike is to be for track use only with no lighting load to worry about than I would have thought you could quite happily run a marginally lighter flywheel. Other things that will be considered when choosing a flywheel weight are valve overlap, compression ratio, piston rock at the top of the stroke.
Best thing is to talk to the experts like JHP and see what advice they give.

The clutch basket isn't on the crank, so it'll make very little difference to the inertia of the crank.

cheers dude!

Can't you run some Dukes without a flywheel at all?

DOH !!!
