<DIV><FONT face=Arial size=2>Hi</FONT></DIV>
<DIV><FONT face=Arial size=2>Could you please tell me if I have to tune the pipe
length for a CD mkII system for the YS FZ91 , I purchased this
system several years ago and have just set it up.</FONT></DIV>
<DIV><FONT face=Arial size=2>If I do have to tune the length how do I do it and
at what length ?</FONT></DIV>
<DIV><FONT face=Arial size=2>I have the Cd mkII pipe +CD header + CDflexible
header + CDmounting system.</FONT></DIV>
<DIV>I am running 20/20 fuel an a 14 x 10 apc prop with a Hyde mount.</DIV>
<DIV>The YS idles at 1950 to 2000 and seems to max out at 8900 to 9000 rpm still
seems rich (lots of oil out of the exhaust ) and the high end needle seems
insensitive until you go too lean and start dropping rpm.</DIV>
<DIV>Any assistance is greatly appreciated.</DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>Thanking you</FONT></DIV>
