dajogejr Posted July 27, 2009 Report Posted July 27, 2009 20 to 21 cc. Personally, I'd go 21 cc and add timing. I ran 150 to 155 for the Main, CEL needles middle clip and 48 or 50 pilots when I had that setup. Quote
TurboBanshee420 Posted July 27, 2009 Author Report Posted July 27, 2009 Thanks Daj... I took it out for some break in last night.....that 2-1 pipe must be choking it off, cause I have 168's in my pj's and it's still lean. Needles are all wrong too. looks like I'll be picking up a head AND pipes before i go back out for some tuning. I was even considering putting the 30's back on just to ride it in some before i hurt it. Ran pretty good though besides the tuning issue. Feels really strong up top and mid range. Wish I could feel wot, but it can wait. daj judging by the size of your jets is how came to the conslusion that the dynoport doesn't have enough outlet to let it breath properly. I can't wait to see what it has in store for me. Quote
