Hello, im still new to working on blasters so i need to know a few things. I had some oil leaking out of the case so i thought it was a good time to do a top end rebuild and put some new crank bearings in while im at it. Bought a new .5mm over piston, rings, clips, pins, bearings, Clutch Cover gasket, carb rebuild kit, crank bearings and seals. Saw some carbon fiber reeds that bolt up to stock reed cage, any thought should i buy them? also going to port and polish the head, and get a bore as well...So my question is after all that should i rejet it while im im doing all of this. Will rejeting make a diffrence? or will the stock jets be ok? Just an fyi this is my first motro tear down lol so try not to answer in lingo i might not know
