Another Front Motor Mount
Was inspecting and preparing the bike for as Vegas to Spokane run and found a crack in the underside of front motor mount. The local dealer had a replacement (P/N 16207-79D) but wanted $80. I wound up ordering the mount from J&P Cycles (P/N 4300140 - OEM P/N 16207-79B) for $42, even with 2-day shipping. The J&P mount is made in Taiwan and is a direct replacement for HD P/N 16207-79B. Package was marked Bikers Choice P/N 49-0754 and tagged with J&P P/N 4300140.
Replaced the motor mount using a procedure downloaded from web (thanks jbhawley). I edited the procedure and tried to saved it as a PDF file attached to this post, but it's too big with the graphic (darned). I will post the steps as another message, but it won't be as helpful without the picture :-) It was 45 minute job using Sears lift and scissor jack to raise motor.
Bike has less vibration at idle with the new mount. Took a test ride and noted a marked vibration at 1500-1600 RPM. The bike is silk smooth at highway speeds and at any RPM outside the 1500-1600 range.
Started investigating the vibration, and based on other posts in the news group, decided to remove the fairing to inspect the fairing support brackets. Yep, found both sides broken. Replaced RH mount 58939-96B with 58939-96C and replaced LH mount 58938-96B with 58938-96C. The brackets were $15 each at local dealer. The small bracket end was redesigned and strengthened in the newer C version. No cracks or stress signs noted around bracket mounting points. The vibration appears to have been be caused by the broken fairing mounts. The fairing still vibrates around 1500-1600 RPM, but its not transmitted through to the bike with the fairing now in proper position with new brackets.
Figure all this maintenance isn't too bad considering the bike has over 45K miles, including a round trip over the Alaska Highway :-)

How's the mount holding up?
Well, it's been a couple of years... old thread I know. I'm curious, how's the motor mount holding up?
I'm debating between trying to find an old style 16207-79B mount (old stock, or for a Buell) or going with a Glide Pro front motor mount.
Thanks,
Brad
