Thought I'd post just as a little bit of info. I weighed a 2001 1.4 flywheel at 8.0kg and a 2001 1.0 flywheel weighed 6.0kg. So quite a difference really.
I didn't take a pic of the 1l flywheel but the excess weight had been removed from the outer edge compared to the 1.4 one. These were both stock parts by the way.Do they both accept a 180mm clutch? The pure weight isn't what you worry about really as much as how close to the edge the weight is concentrated (rotational inertia) Still, 2kg IS a lot...
Even if you could remove excess material Tom you would still need to have it balanced and refaced due to the fact it may warp due to the different stresses throughout the flywheel once machined.good work there! if only my lathe had 50mm larger cutting diameter!
Many years ago I had a fully balanced engine in my Westfield. It was a lot smoother compared to other engines of the day. To be honest now though most modern engines are now equally as smooth. I get it with the weight issue though. A lot more revvy.would like a lightened balanced crank as well...... but heres to wishing!
yeh-man, £50........and thats supplied too ! http://www.micra.org.uk/threads/f-s-1-3-flywheel-lightened-and-balanced-by-me.58708/You may be surprised how little it costs to have a flywheel machined and balanced.
You might as well get that one off Frank. It'll probably be cheaper.sounds pretty good, i'll have to go speak to my local machineshop.
