i run klotz R50 synthetic at 40:1, the only time i replaced a plug was after i had motor work done.

 

on my LT250R i ran 32:1 but since the 500 is a lowerrevvin engine, u can run 42:1 with no problems if you use a good oil like Golden Spectro Synthetic.

 

lol so true, im the only one that can start my quad, all my friends have tried but couldnt do it.

 

oh yea, and try giving it a little throttle when kicking it, that helps mine.

 

this is a bad question but how do you tell if it the stock carb, sorry but i do not know too much about them and that is why i am here... thanks

 

Go to the dunes: Please keep in mind that when you change oil ratio's, that you WILL need to do some re-jetting. And chances are your jetting being off will typically make it harder to start... Food for thought.

The old days, the mfg recommended 20:1 ratios, but that's with the old dino oil.... the newer synthetics recommend 32:1 and up... Pick your poison, and jet accordingly, and stick with it... that will yield the best results.

 

the stock carb is a mikuni with a rectanle slide..... i can get model #'s if u need it

 

do you have a pic of the carb or know of a site i can visit and, thank you guys for the help

 

Can you see what # is stamped on the left side of the carb?

I remember seeing old post's on most of your questions dude. All you have to do is search.

There is ALOT of good Zilla info on this site, for free!
