2015 ULTRA 103 ENGINE REPLACEMENT?
Trying to decide on best route to take I have a 2015 ultra with a twin cooled 103 engine
just found out the crank is twisted and main seal is bad so oil from engine side is leaking into primary
motor has 60,000 miles on it
I ride 2 up about half the time and I ride often
do I rebuild and go up to a 110
or get a long block 124
or any other options ?
current motor has woods 222 cams
power vision tuner
wideband O2
man o war compensator
2 in1 exhaust short

Go to dark horse or local and get crank fixed. The sprocket shaft seal will be replaced at same time.
I brought bottom end to dark horse with bad bearings. $1900 they returned bottom end sealed up.

Perhaps (other than a sudden decel or burnout that twisted your crank) that MOW acts too much like a solid sprocket. The newest stock comp (which has the upgraded harder center) would meet your needs better.

I still question why they changed. Were/ are the big evos having issues with comps?
