I had a LT250r for years but for the last couple of years I spent more time fixing it than riding it. So I sold it and bought a 400ex with many mods and it was very nice looking, scary fast and reliable. The only downfall was I hated taking it in the woods because it looked so nice, gas costs 6.00 a gallon, and it wasn't very practical in the woods (wide, liked high rpm's) it was built for MX and I'm to old and fat for that so I sold it and bought a used 2004 Z400 and WOW. This thing seems much lighter and handels much better than the 400ex. I do have a couple of questions what fuel do you guys run 98,92,93 ect. and what gearing seems to work the best. It has 22 inch Realators on it now but I don't like them I'm getting 20" Kenda XC's for the woods what is the best sprocket to run on the front.

 

When I had my Z I ran a 42t in the back with 20in razr2's, worked real well for me.

 

if the quad is stock then 87/89 fuel. I run a mixture of 92 and 105 race fuel in mine but then again I have to because of the motor work
I run 20" shredders on the rear and I run a 14/39 gearing.
as for 22" tires I think 14/42 or even a 14/43 would work great
