Kdx200 I just bought a 2000 KDX 200 off of Craigslist and it's my first 2 stroke dirtbike. I know 2 strokes blow some smoke but when I rev it it blows more smoke than I think is normal even for a 2 stroke. I've been putting in Stihl chainsaw/lawn mower 2 cycle mix at a 1:32 ratio which is 8oz per 2 gallons of gas and from what I've seen on the Internet is what you're supposed to use. And also in neutral with the clutch out idleing it makes a clicking noise. The final problem is that when it is first started it will idle all day but sometimes after riding it it needs gas to idle. I realize that it is a old dirtbike and it'll inherently have some issues but I was just curious if these are mechanical problems or not.
