I have heard alot about removing the baffle can harm your engine. I have a k&n filter and have removed the baffle, and just checked the spark plug i put in 6 months ago and it looks almost new. Should i be worried?

 

Well removing the baffle won't really give you any more power, it will just make it louder. And the K&N will allow more air, so technically you could be running slightly lean. But if you keep the air box lid on perhaps the K&N has not increased the air flow enough to make any real difference.

 

if your runing lean will the spark plug be black and sooty or white and burnt looking?

 

If you are lean the plug will be white or yellow-ish........ and I've even seen them where they are cracked..........Since your plug still looks good as you say, I would think you are pretty safe.

 

Also...I would rather error to the rich side if my air /fuel mixture was a bit off...but as ss said if your plug looks as good as you say then I would think you are fine.[img]i/expressions/face-icon-small-smile.gif[/img]

 

if i was to take the airbox lid off what size jet do you think i should use?

 

if you were to take off the lid and remove the muff.tip a 142.5 -145 MJ
by remove i mean using a hole saw and cutting the center out of the spark arrester that came with , or you could replace with an after market end cap .
just that much could bump your HP up to 3-4 HP ,change your air boot to a 400ex
boot and bump it up some more . after that HP starts to get expensive ,about
$100. per HP. cheep HP is the best HP.
