<font size="2" face="Verdana, Arial">I'm still mullin' it over... on the one hand, I *dread* tryin' to jet the damn carbs with the airbox in place... I have allens in the caps and float-bowls so I don't hafta pull em to tune, but that airbox just eats up so much space and makes everything a bear to reach. ...I *know* that altitude plays hell with jetting... I live no more than 100' above sea-level, but most of my summer riding takes me into the mountains, and my *favorite* set of twisties is a forest-service road that goes nearly to a peak ...but then again, even the fuel-injected, stock-airboxed viffers start to wheeze up there too... and I can *still* do wheelies at the top with the old 36mm carbs and BMC filters... I was hopin' to find out for sure whether or not it was worth the trouble before I spent a buncha hours only to find that it's not...Originally posted by Bones_GSXR:
Another thing to lok at is where and how you ride. If your rides vary in altitude by more then a couple thousand ft then where you tuned it for and you run open element airfiters you will be running too rich or lean depending which way you go. An airbox helps to keep the density constant to the carbs taking care of this. Tempature also Plays a part in this. I re-jet twice a year once in the late Spring when the temp passes (and Stays) over 70 and then agian in the Fall when it drops back down. I keep the Fall jetting thru the following spring.
