Author Message   Johnnyrocket246 Posted on Wednesday, September 21, 2011 - 05:04 pm:        what is the best and easiest motor swap, (9or 12)for my uly if the crank goes out. whats the best year.   Froggy Posted on Wednesday, September 21, 2011 - 05:15 pm:        Your bike is an 07, you best bet is to get another 07. When you start picking different years, you start needing to change components. Any 04-07 XB12 motor will drop in with minimal fuss.   Johnnyrocket246 Posted on Wednesday, September 21, 2011 - 05:23 pm:        thanks, froggy, but if i get another 07 won't i be back where i started with a bad crank?   Froggy Posted on Wednesday, September 21, 2011 - 05:33 pm:        Maybe, maybe not.   Reepicheep Posted on Wednesday, September 21, 2011 - 07:00 pm:        Probably the best bet is to catch it early, and just rebuild your motor with the 08 crank. That will probably solve the problem.   Johnboy777 Posted on Wednesday, September 21, 2011 - 07:36 pm:        ""Probably the best bet is to catch it early, and just rebuild your motor with the 08 crank. That will probably solve the problem."" That might not be possible. It could be more of an on/off thing - happening all at once. Maybe Hughlysses and some of the others can chime in with regard to when they first noticed their engine going south. ..   Coolice Posted on Wednesday, September 21, 2011 - 07:46 pm:        We used engines built by Hoban Bros with a 08 cranks in them. They can do it so the engine components stay the same. I have done the conversion to the 08/09 motors and have a good list on what you would need if you get a newer motor.   Desertdweller Posted on Saturday, September 24, 2011 - 12:27 pm:        I would love to see a list of parts needed for a newer motor swap. It would be like my list to Santa Claus.   Paint_shaker Posted on Saturday, September 24, 2011 - 01:32 pm:        Only indicator I had for crank failure was a clacking noise under acceleration. Otherwise, bike ran fine and still pulled hard. No metal was found in the oil. The four options I considered were; 1) Swap for another 06/07 motor (but may end up with another bad crank), 2) Rebuild using old crank with new bearings (cost was only slightly nower than a new one), 3) Rebuild with new crank. 4) Part out on ebay. I found the most economical to be rebuilding with a new crank. The easist and quickest would be a straight motor swap (04-07), but may not be the best way.

Is that rebuilding w/ an 08+ crank, and what were your cost numbers, if I may ask? Thanks .   Johnnyrocket246 Posted on Saturday, September 24, 2011 - 02:14 pm:        thanks for all the input,putting a new crank in is probably above my abilities, am thinking of finding a motor and storing it until i need it. the question is what year, are the only crank issues with 07. i would like a direct swap if possible. thanks again for the input trying to make a informed decision .
