i just took the baffle out i think it sounds good and a little better throttle responce but will i run to lean or rich? (I plan on runnin it like this till christmas)

 

You will run leaner with the baffle out.

 

yea but will it hurt the engine or anything else?

 

That's tough to answer, and I will tell you why:
99.9% of the time you will be fine because most engines are jetted a bit rich from the factory. Now lets say you are a sea level and it's a nice cool day with lots of 02 in the air and you are jetted a bit on the lean side to begin with............... your going to be picking aluminum out of your exhaust port.........you get my point.
Here is a down and dirty way to know if you are rich or lean. I your engine starts without a choke when it is cold, your fine and quite a bit rich. If you start it up and it idles rough or dies without a choke, then you are right there on mixture. If you need to choke it for a long time after startup then you are lean to begin with.
All in all, I would yank the baffle and have fun. Keep an eye on your plug and you'll be fine.

And all this crap about burning valves and all of that; it's just that, crap.

 

well today in upstate ny it was like 60 and a bit windy it started without the choke fine so i think i should be ok. thanks for the help

 

60 degrees is one thing, but when its 30 it will be a different story. And it gets a lot colder than that up in NY. If you arent choking it a lot, its not backfiring and the plug looks good then you should be ok. You can always tweak the pilot a little too.

Doc, glad to see you around and still helping on jetting issues.

 

well when i first started it today it backfired as soon as i started it and that was when i gave it the gas and that was the only time is this an indication that im runnin to lean?

 

You could try going out on the mixture screw, about 1/4 to 1/2 turn. This will help the backfire/ cold start symptoms. Heres an article on jetting and drivability symptoms of lean and rich.
