Lightweight flywheel
 
I have a lightweight flywheel but i have noticed that my standard flywheel had a bearing in the middle of it and my lightweight one doesnt....

I have a bearing in my lightweight flywheel.

What make is yours mate?

Gava 09 June 2014 06:44 PM

i dunno to be fair i cant remember where i got it from its only when i looked at my standard flywheel when moving it at the weekend and i thought hang on my lightweight one didnt have that

Its the spigot bearing, usually come with new lightened flywheels, either replace it or knock out the old flywheel & fit to the new.

Gava 09 June 2014 07:30 PM

oh right cool ill order up a new one then

I have had motocross bikes with lightweight flywheels but have always assumed they would be no good for a daily driver as it would be jumpy in traffic etc. Am I right or wrong?

If you go too light then pulling away does become a pita, I have a 7kg flywheel which is fine, if you go lighter then you will start to find it gets harder.

Gava 10 June 2014 08:36 AM

Yeah mines 5kg and it judders like mad pulling off

Juddering is not caused by the flywheel weight.
Lightened flywheels have reduced mass therefore lower mementum than full weight flywheels which are used to stop the engine from stumbling when pulling away from idle.
Juddering is caused by clutch bite.

So my juddering will be down to the 6 paddle clutch I have just fitted then

Had a 4.4kg Fidanza fitted to mine. No issues at all.

Most probably.

I used to have a 5.25kg flywheel and 6-paddle helix clutch and uprated cover, hydraulic conversion T5 gearbox fitted to my old sierra. it was easier to drive than my daily was.

spigot bearing should only be a couple of quid from subaru

They can judder when first fitted :) Don't panic just yet :)

LWFW's are great IMHO :) Easier on a 5 speed but by no means hard work on a 6 speed :)

So i fitted a new center bearing to the flywheel and jobs a gooden, pulls away smoothly now and really notice the difference in the way she revs with the lightweight flywheel
