Well, tonight I went out for a nice long ride. Almost forgot I was only warming 'er up. Anyway, while riding, I noticed the backfire was much less, although still there. It also felt like I had more power. I never made any adjustment since the other day. I returned the mixture screw back to original the other day- 3.5 turns out.

Could turning the screw like I did and back out to original have done something for the better? There was no change in the mixture setting.

I left it as it is since it seems somewhat better. I was thinking about doing the spacer mod but am not sure if mine is an adjustable needle. I guess the only way to find out is to open it up. Can I get to it without removing the tank or the carb? It doesn't seem like I can get to those cover screws.

Thanks, will open it up tomorrow and see what I have for a needle.
