Looking at going down to 500's to get a weee bit more performance and with any hope a tad bit of mpg improvement. Pro's -cons? All stock with a HPS stinger.
Thanks AL

i tought the 800 2002 came out with 500N stock...i will check the book

520's are it.

yes you are correct...

Don't forget that they are 520N and not 520.

So, safe do so and still maintain reliability? Anyone have some exp. with the switch?

Went from 520N to straight 500 on my frist step down with no problems this is riding northern ontario

01 800 come stock with 500. I think you'll be cool

sorry guy that last post I made is false it was the 01 summits that used 500. mxz were 520. :cussing:

2001 mxz700 came with 520
2001 mxz800 came with 500
2002 mxz 700 came with 520N
2002 mxz 800 came with 520N
Remember 520 and 520N are not the same.
520N is a 560
520 is around 490-495 beleive it or not

I ran 500 in my 02 mxz 800 for most of last year. Tested on lake at -17 Deg C or 1 Deg F. I fatten it up if it gets colder. Remember read plugs and piston wash after every jet change. Jets are cheap motors are not. :sly:
