i have a few questions about this sorry i am sure this has been ask a few times, but what kind of conditions should i put the lid on for and if i run without it do i have to rejet or not?
thanks

If it's wet out, run the lid. If it runs alright with and without the lid, its not that big of a deal with jetting, but you'll get more power both ways if you jet it each time.

ok thanks for your reply and now i have this very small oil leak coming from in front of my sproket(i replaced and broken side case and a little bit of the motor side got a little scrape) is there a simple way to fix it with out taking off the side case and buying a new gasket?

Not that I've heard of, sorry.
