Title: Re-Jetting suggestions? 541cc overbore with K&N and pipes.
Post by: 5thAve on January 12, 2009, 08:05:44 PM
My winter rebuild will include boring the cylinders to 541cc with the 78mm Wiseco Kawasaki pistons mentioned by Dgyver here: http://gstwins.com/gsboard/index.php?topic=14401.msg123943#msg123943 (http://gstwins.com/gsboard/index.php?topic=14401.msg123943#msg123943)

Assuming I also go to a K&N lunchbox and aftermarket exhaust, can anyone here who's run a 541 suggest a starting point for my re-jetting?  :icon_question:

In my 541... I was running 147.5 mains but they were in 36mm carbs along with Megacycle cams.

Okay, well that's a start.  Thanks dgyver.  I'm planning to try stock carbs and head, including cams, for now.

Any other opinions?    :dunno_white:
