hi, i mostly ride trails in hungry valley, CA and I've been pretty lucky since they've let me in even though i don't have a spark arrestor. I use a fmf powercore 1 and i cant seem to find anything other than the cobra sparky that would work as a spark arrestor. I dont really want to spend 70 dollars and was wondering if there is any spark arrestor screen (some thing like the Big Gun spark arrestor screen) that would fit on the powercore? please let me know what i can do to put a spark arrestor on this quad
Thanks

 

Guess if you could put in a stainless steel screen on the inside tip of your silencer that should work most cali rangers just test for sparkys by inserting a rod into it and checking for a screen.
