This may seem to be an offensive question but... Are you aware of how much a 2stroke should smoke? I only ask because you say you just switched over.... Try running it a little leaner... I know when I ran 32:1 My quad smoked quite a bit and I just switched over to 36:1 and it made a huge difference. Ran a lot better and smoked less.

This comparison isnt a good one but... Take my weed eater for instance lol...

Wont run right if at all if I run it 32:1... But when I run it 40:1 it runs perfect.
