spark arrester

how do you remove the spark arrester on a j.d hpx. and does it improve the performance any???and does it mess up anything on the engine by doing so??

If it's a diesel, just remove one screw and pull it out. It's a real fine mesh and looks like it would carbon up pretty fast. I removed mine and the engine has a deeper sound and better throttle response. Keep it handy in case you ride in an area that requires a spark arrester.

it's gas i didn't see any screw it just looks lik it reduces the end of the tail pipe size.i'm trying to post some pics but it keeps sayin they are to big???

Tommy, Here is a free program for resizing pics that are too big to post .

When removing spark arrestor it should reduce back pressure which would help bottom end a little ,but then top end would suffer a little (needing to jet up) at high speed.

Tommy,

Look under the arrestor toward the engine side. It's a pretty small hex-head screw.

Take out the screw and the arrestor will pull right off.

i found it !. the sucker was a little clogged i have it off right now but i plan on cleaning it and putting it back on. i didn't notice much diference without it(alittle bit).i think i'm gonna try and back off the bolt on the floor under the gas pedal to see if i can get anymore out of her there(not that she needs anymore power).
