What tire is the best for trail riding and like little bit of jumping. Not sure but heard hole shots are good this true or no.

 

They're all good. What kind of trailriding do you do? Is there a lot of mud or is it dry? If you are in muddier conditions go with the RAZR2s. If not I'd go with the Holeshots or RAZRs.

 

I agree with z250freak, the Holeshots or Razrs are both very good for trail riding.

 

I got razr 2's and i do the same riding u do basically. i love them and i think they are better than the originals.

 

I have the six ply RAZRs and love them. mahoe do you like your dmc exhaust and how does it do? mine is ordered and should be here on monday. If you want to see the z250 with razrs check out my pics

 

THe DMc PIPE is hell of lot louder than stock and yes there is little difference from it but not much. I think i might need to Re jet cause in california u go from like 1000 elevation to like 4000 in the matter of moments. But if you like the loud ness it is awsome. But i do have to say that the Z250 is anyyoing to look for mods for cause no websites have the stuff. The only website i can think of that has stuff for it is ROckymountainatv.com. There still not much for it. Need to sell my z250 and get a 400

 

I did order the quiet core ,so that should help with the loudness,I hope it doesnt rob to much power though !
I cant beleive you didnt notice a big difference in power, but like you said your jetting may be off
