here is one for yua,i got a DLA56 that had the shakes. then i started to look at the prop hub while turning it and you could see high and low spots.so i orderd a hub for a DLE55,because i didn't know for sure that i would get a good one from DLA.anyways the hub bolted rite on, just like it was made for it,timing included was spot on.
i know this is no news to some of you,i just thought i would pass this on.
also that took care of the shakes,and it turns with in a hunderd rpm's as my well broke in DLE55.
