Some Testimonials on the
name is Andrew I live in north west Alberta and ride the Pacific Northwest as
often as I get a chance, for the last 4 seasons I've been on an 09 M1000 and
most of the time she's king of the mountain, however a good friend of mine
recently bought a new 8000 proclimb and installed one of your 925 kits and he's
making me look like a fool!
Typically I don't like to stray too far from stock when it comes to engine
modification because reliability is pandemonium in the back country but this rig
he's running seems to work awesome!
