dose

Hey guys, lightened my flywheel a while back for more acceleration, got lots more! But dose feel like I've lost some speed.. Dose lightening them take away some top speed? I don't see why it would baut can see how lightening it helps it get going quicker.

Is it ok to ride my bike with a leaky tappet cover? I thought I shouldn't but when I was lookin on eBay for replacement ones most of them had breathers anyway..So dose it matter if it's not 100% air tight on there ?
