Engine vibration/loose?
Hey guys. First let me introduce myself. First part. José from Staten Island.
. I have a 91 flhs with 80k on the tach. I recently replaced the fork seals due to a leak. I raised the bike under the motor with a jack and block of wood.
. Shortly after during a ride I stared hearing some rattling on decel. It became progressively worse in a matter of 20 miles. At first I thought it was something in the forks but I soon realized that the rattling is a vibration in the motor. It takes and shakes badly on decel or around 1800 rpm on side stand.
. I just replaced the front isolator and checked the top centering mount. Everything felt nice and tight.
I still have not checked the bottom centering mount for torque.
. Next ideas are rear isolator mounts..
The motor was replaced 4 years ago 8k miles along with the mounts.
. Start am I missing here. Motor runs like a top.the rattle/vibe started slowly increasing in stregth and noise leading me to Beleive something loosened.
Why would my motor be rocking and rolling in its frame.
. Thanka in advance

I'd check all the motor mounts.. In particular the ones between the motor and tranny.. Also check the exhaust system.. It might have cracked a mount.. Rear head pipe can split.. Motors on the rubber mounts can bounce around some at idle..

Update
. I took tank off checked stabilizer and new front mount. With tank off and some fuel in a bottle I ran it for 5 minutes trying to recreate the noise and vibe. It didn't do it. Changing clutch cable today and will see by this weekend if she continues to rattle

Well you almost had me. Until I seen an amp and extra wiring so I could use the stock controls. I really would rather have a plug and play unit. I have owned many dressers over the years and only had one issue with an H-K uniit. The CD player stoped working.
I really see no reason a bike needs an amp, I would rather just ad a better set of speakers for a crisper sound. More power doesn't mean better sound.I
But I do appreciate your imput, thanks,
