hmmmm .....
543xp - 9.92 lbs - 2.95hp;
- no autotune, no quick release air filter, no combined choke/stop, no revboost, no fuel level, no retained bar nuts
545 - 10.8 lbs - 3.35hp, 3.06 cu. inch ($100 or more cheaper than 550xp)
yes to autotune, quick release air filter, combined choke/stop/ revboost, fuel level, retained bar nuts
550xp - 10.8 lbs - 3.75hp, 3.06 cu. inch
yes to autotune, quick release air filter, combined choke/stop/ revboost, fuel level, retained bar nuts
. . . I'm still thinking 545 instead of 543xp
How small do they make the Techlite bars? Maybe can get the 545 down to closer weight to the 543xp.
