I am putting 14 in. Paul Yaffee monkey bars on my 2009 SERG. What length cables should i go with. 
I do not want them to long. Thanks in advance.
Here is the list provided to me by jim glide:
Here's a list of the Parts needed to complete the installation for the 14" Paul Yaffe Handlebars with the Heat Demons:
Polyurethane Riser Isolators: Part # 56298-03 optional
Brake Line, Diamond : Part # 41770-09
Brake Line, 40" : Part # 1741-0058
Clutch Line S/S BT : Part # 1741-0471
Twist Grip Sensor Kit (TBW) : Part # 32310-08
Symtec Heat Demons : Part # 210045CRET. I purchased the right side clamp control because my Rider's Claw I-Pod holder is mounted on the left side of my handlebars.
I also remember purchasing a banjo fitting for one of the brake lines mentioned above, but I don't have that Part #.
I hope this helps and good luck with your project.
PS. I purchase the 8" wire extension kit, but they weren't needed after all.
