Depends on how many holes and how big they are........Was just wondering what setup I should be running on my 660. Has a Yoshi full exhaust, stock airbox (prob gonna drill a couple holes) around 800' elev. What should I set everything to to get max performance? Thanks in advance
The more big holes the better, jetting for an open air box is #25 pilots, aftermarket needles half way up with 160-165 mikuni mains.............Probably gonna put two 1 1/2" closer to the front of the bike. Unless you would suggest a different set up? Open to ideas. Still learning.
