Hey! I'm planning on removing the airbox "restrictor" on my Euro-model 99 WR. I guess this will lean the jetting. Do I therefore have to counteract this by riching the jetting? Is it a simple case of raising the needle, or do I have to change jets? I normally run at nowhere higher than a 1000ft altitude, and mainly at sea level. Any ideas on jets? Your help would be appreciated! Thanks.
