there are so many different opinions on what is MOST important.. but..
the YFZ is a GREAT quad in stock form..
that being said...
the Intake is an area that needs improvement
I would recommend the Ron Woods or the FCI
both do a great job, and the Woods is a bit cheaper..
Exhaust.. (there are a MILLION)
I gotta Recommend the Barker..
EXCELLENT quality (as you 700 guys well know)
great HP
quiet core is available..... (this WILL make the DB regs.. and on my 450R, it only lost a half of a horsepower)
spark arrestors available
and they just look GREAT!
and sound AWESOME!
Talk to Kenneth at KB or Steve at TQS for pricing
one
IMPORTANT mod/upgrade you should do is the
"oil mod"I would look to J&T for that
200 bucks and it is DONE!
they are located in Lapeer MI (right down the street from Tim Barker's Shop)
http://www.jtatv.com/SearchResults.asp?Cat=4even though she may not abuse her quad like some of us do..
this is a known problem with the pre 2007 YFZ
the
Cam-mod is free, and helps add a bit more "seat of the pants" HP
the
"o-ring mod" is free, and helps that "off the line" BOG that so many YFZ's have
the suspension is a bit of a personal thing .. expensive.. and maybe not needed for her
does she like to fly?
the YFZ is a jumper.. if you want it
in that case.. some good arms and shocks are priceless..
if not.. leave it alone..
finally.. some sexy OneIndustries Graphics!!
