flywheel lightening

[dazrave]

im thinking of getting my flywheel lightened.

i have a couple of questions
1. what are the benefits or complications
2. how is it done and where are the material taken from?

anyone recommend a place / dealer

cheers DAZ

Beedspeed - mine was £12 to be lightened (can't honestly say how well they balance them tho, as I've never tested it. Fins were shortened, all front face was skimmed down, outer edge of flywheel was skimmed down and some of the rear shaved also and all for 12 notes. I'm sure Oz has placed a picture of his recently lightened PK wheel on here somewhere

Complications = if it ain't dynamically balanced then at high revs it fucks your crank and bearings ( thnx Mr Broadhurst for your shite lightened lammy flywheels ) some people experience a loss of torque gained thru the inertia of a heavier wheel

Benefits = higher revs, faster acceleration, posing and a minimal reduction in the 3rd to 4th jump on standard gearboxes

heres pics of one beedspeed just did for me, £12, but postage mounts up to about another £10. they took loads of this one, i asked for as light as possible, but supprisingly its still 1600g's, i'd go for hp4 if i had the spare cash, i've had one before and they're the nuts

i take the fucking lot off and screw a plastic fan on to the front of it, although as ive learnt if you go to mad the magnets have a habit of departing the flywheel

Yes - and this can pretty hurt (either you or you smallframe).

i once saw a flywheel breaking off completely and after a 100ft balistic flight coming to a halt between two parked cars. (uups!)

I managed to lighten my PK flywheel to 1250gramms without impairing strength.
