I have 2 maxxis all-trak on my 9" stock rims and my buddy wants to trade with me. I am getting 2-18" turf tamers mounted on 2-.190 douglas 8" rims and 2-18" fast trekkers mounted on 2-.160 douglas 8" rims. What do I have to do not to lose any top end? Thanks!

 

Try the 16 tooth front sprocket, I didn't try it but I hear you have to grind or remove the case saver. You could also try a smaller rear sprocket, 3-4 teeth smaller should get you back around original speed. don't try both that would be overdoing it, and you would have an outrageous top speed. You could try it before you change it, you might like the added acceleration, I bet you could really spin.

 

300ex or 400ex?

 

I have a '98 300ex
