how can i get a deeper sound on my z250 what should i do

 

i put a yoshimura slip on pipe on my z400 it sounds sick

 

If you want to change the sound on your quad then you need to chose a pipe.. also having a high flow airfilter will change the sound.

 

just take the whole exhuast off you don't need it and after a while since you don't have backpressure your valves and engine will be shot lol j/p...I would look for a slip on and you will hear a difference and also get yourself an airfilter...Try looking at hmf, yoshi, or procircuit...Make sure your rejet the quad with these mods though.

 

How do I rejet my z250

 

Well depending on what mods you decide to do will determine the jet size you will need to go with...You will need a new needle, main jet, and maybe a pilot depending on the mods...Once you have the quad jetted you will need to tune the quad by the adjuster at the bottom of the quad and after riding it for a little bit you will want to check the color of your spark plugs and make sure they aren't white (lean condition) and you will be looking for a tannish color which means it is good and a black plug means a rich condition.
