My 660 is ITP wheels and Bighorns, the rest is completely stock. Mine will go 65 maybe 70.

Too bad they don't make a pc3 for a 660.

EDIT: And I bet your speedometer is reading kph not mph. Theres no way it will hit 65 mph that fast with the mods you have.

I see he has 700 so perhaps he got them mixed up.

Also not to be a hater as I love seeing a good ole fast 660 but you have your speedo set to KPH (kilometers per hour) instead of MPH, so really in that video you where only doing 40-41 mph. My 660 will really do 62 MPH with stock clutch but those last mph take awhile and its screaming, that's with my iphone gps, speedo was 59 MPH i believe.

EDIT: I see wrecked noticed it also

2003 Grizzly 660 came with new 26" BKT Wing tires ($2300 craigslist)
1" wheel spacers ($78 ebay)
Yamaha Overfenders ($92 ebay)
3500 lb Viper Max Winch + Amsteal rope ($185 +$44)
Custom Aluminum Tip ($5)
New rear pinion housing +Seal ($54.00)

New right rear axle shaft ($49 cvman)
Alba Steering stabilizer/damper(Cost $98)

Mine does 68 maxed right out on stock clutching. I hit 60 pretty quick but those last 8 mph take a little bit.

To change it back to MPH, hold down the two buttons on the left side of the display while turning the key on. Wait for the display to light up before releasing the buttons.

That bike is a 660, and there is no such thing as a PC3 for a carburated anything, lol. Good laugh though.
