I put the new Air/Fuel mixture screw in it today, the stock one would not fall out after unscrewing it, had to pull the exhaust off to get the float bowl cover off so I could pull the stock screw out, time consuming but got it done.
I put the stock muffler back together should have less back pressure now and has a spark arrester screen in it now.
I was able to find an 03 CDI for quite a bit less than an 06 so I will put it on shortly, hope to get that low/mid grunt I have read about on this site.
Before I start it I am going to install a 48/170 jet set, don't want the engine to run lean. I should be good to go after this. Then I need to Ride It!
Thanks for all the help on this topic everyone!!
