flywheel is just a spinning mass which provides a gripping platform for ur clutch plate...
wanna ask here... currently i'm having the suffer on the JPJ inspection for transferring of ownership. they failed me due to the glass is not meeting the requirement..
Just wanted to ask those of you who've removed your speed limiters, are you guys still using your stock speedo or have you changed to an aftermarket speedo?
