Best Mod,s for a 660 Grizzly

[06 Dragon]

Just recently purchased a '03 660 griz, and wondering what are the best mods for more power. It has 28" mudzillas, clutch kit, and a K&N air filter. Do they make a chip or cdi box for this year?

you can get a CDI box. Pipe it. If your looking for low end power, do a mud buster cam.

More power, the more likly you wil break the little grizzly axles. Beware.

Put a pipe on it ,you will notice a difference

Thanks, What type of pipe and cdi box would you recommend? I don't want it too loud.

Best mods done to mine were the pipe (HMF Penland), Mudbuster cam/Wiseco piston combo, clutch kit (EPI mudder) and snorkles. Not much of a difference with cdi box (removes limiters wich is nice but doable for much cheaper). I also have a stroker crank in mine but now have to run race fuel blend cause of added compression.

Dragon, have you done the mods to yer Grizz yet ?? I have also have an 03 Grizz & here's what I have & would highly recommend.

The Pro Design K&N air fliter kit
EHS air box lid
Leo Vince X3 pipe (I really like this & it's not loud at all)
I put a machined sheave for a 660 Rhino in from Fix Power Sports Hunterworks.com Greaseless clutch kit (also for a Rhino)
Hauck Power Sports CDI (gives you about 1000 more RPM they say)

And I just installed a 686 Big Bore Kit with a Raptor cam along with some mild porting & polishing ... I really like this set up.

With Large tires My Mod#3 will be the best bang for your buck! this lowers the take off ratio by 6-7%, so now you will be starting off in 1st gear, instaed of 3rd because of the taller tires.
This mod will not hurt your top speed like my Mod#1 shim mod did.
If you are interested, check out my web site.
Thanks
