Hey guys, Just got my new 2014 yz450 just finished run in, suspension,sag clickers etc all set to my weight. i have now got 4 hours and just done first service. i will be dropping my forks about 4-6 mm for more weight over front and better turning in corners.( Had to do this on old bike as well) Have done fuel breather mod, but ran mine between side of air box down them up along wiring loom to the top of the stem head,much neater then drilling holes in my opinion. Still unsure or crank case breather mod????? ordered bash plate in case lol my biggest issue is wondering do i leave stock pipe on,Is there a mod you can do to the stock pipe? spark arrester or do i get slip on pipe thinking of a fmf. if i get a pipe do i need to change maps, my research says no but others say yes. Or if someone is local gold coast they l could pay them to change my map instead of buying a tuner as once set l will not change it.
