What kind of riding are you into? THis will dictate which way you should go with your gearing. If you like the trails stick with the stock 13t front, if you like ***** out riding then I would suggest stepping up to a 14t front, the Zilla can pull it no problem. As far as performance mods, a pipe, reeds,air filter and carb mods will really wake up the 500. I would suggest the LRD pipe, but they are no longer in production. As a second choice I would pick the paul turner pipe. This with a 39 or a 41.5 carb with Boyseen reeds and a K&N filter will make the Zilla feel like a new beast.

 

hi:
i just ordered a fmf fatty pipe a barnett dirt digger clutch. can`t wait to get it
i hope to feel the difference. i had gone down a tooth on the front sproket. and i regret it. it really hurt my top end.

im going back to the 13 toothe asap.

i ride a lot in sand pits . and some trail.

i hear mixed feeling on the barnet. what do you think of using the barnett disks w the old springs

thanks

 

I am running an FMF Fatty w/Answer pro exhaust, I'm happy with it.

I usually run a 14 tooth in all around situations, but drop down to 12 in the sand, because I run tall paddles.

Haven't heard anything bad about Barnett clutches, but you really should get new springs. I run a WB clutch with a hinson basket.

 

hey ZOO;;

thats the same combo exhaust that im runnin :-)
what are you running for a carb? if its new tell me where i can get the next size over the stock one.... what is the stock carb 36 mm mikuni?
