what should i buy

There's a good idea! Or talk to little3mill and get some PC work done. He's very reasonable...

And he's close!! But I already spent it, I bought assorted jets for when I get a cfm airbox, a headlight body (thank god because mines got almost half missing)
A sprocket oil seal, And last but first, an LCD screen for my gopro.
 
The oil seal behind my sprocket it's leaking (which I wouldn't have found without a SLICKERTHANYOU LEAK TESTER:p)and the leaking oil.

Wait! If your getting air out of the sprocket seal, Either a bad crank seal on the clutch side, or bad case seal or broken balancer housing. Only part that sees air is the Crank and top end! Better check again! But thanks for the plug!
