Holes in left side air box?


 

I took off the left side cover and found two 1" holes in the left side
airbox. Is this good? My bike seems to run a little lean. The
previous owner must have done some mods. I am not sure if any of the
needles have been swapped out.

Sometimes in an effort to get better breathing holes were drilled in both left and right sides, two 1" holes each side being popular. This was done instead of removing the snorkel from inside the airbox. Strange that you only found them on the left, unless it was an effort to balance out the two sides. Never heard of that one before.

Dennis,

The holes are probably on the right side as well, I just haven't
checked yet.

Could this "better breathing" be counter productive for the stock
mufflers? I think the holes were drilled because the previous owner
was using after market mufflers.

May not make a noticeable difference in running. The W is very forgiving in the way the carbs are set up. I wouldn't think it would be counter productive.

Get Jon H's opinion.
