Message: [QUOTE="Dirtbike'n man, post: 844431, member: 51604"] hello people i have an 03 yz 250 and i plan on racing hare scrambles and right now i have an sst pipe and shorty silencer on the bike and i was wondering if i get a sparky spark arrester for the shorty because i love the power of the bike right now as is and i was thinking of either just getting away with the sparky or getting an fmf turbine core. with either of these will they change the power and will have to re jet the bike for these changes or will it be so small a change it wont affect it. which would you people think i should get for hare scrambles and if i do get the sparky will that make me legal to race or could i just run the bike as is [/QUOTE]
