New to me 2006 GL1800P

[Dagostini]

I just purchased this 2006 black 18000 with 83,400 miles on it. It has been riding pretty nice. I notice a bit of bearing noise when turning left, so plan on changing the front wheel bearings. I'm and engineer and work on my own vehicles a lot. Anyway, any suggestions on other maintenance I should do other than oils, filters and plugs?

Are you sure the noise is bearings and not the tire? They can make some odd noises once they have some miles on them. When I got my '01, most of the handlebar pushbutton switches were all gummed up, I pulled them apart and regreased them. Like you, I'm also an engineer and do my own maintenance too - the switches were a REAL pain to do, my fingertips hurt for days! It seems the grease gums up after some years so you might consider it a winter project. I would make sure you list has the rear differential oil, brake fluid and antifreeze if it's not on there as well as brake pads if need be. Good luck with the new bike, I wish I could keep riding mine but we have this thing called winter up here ....

My first guess is your noise is tire related. Usually it is caused from a cupping rear tire .... whonk, whonk, whonk !!!

Front bearing are easy to inspect ... there are 4. Once the front tire is off, stick your finger in the spindle hole on each side. There are 2 identical bearings on each side. Rotate each bearing 360 degs with your finger. Any roughness indicates a problem. Next, put those axle spacers into their appropriate place. If the seal is good, they should not fall out. Inspect the seal surfaces on the spacers for any sign of roughness.

If new parts are needed, be sure to replace with Honda parts. There is lots of aftermarket junk made for less money providing disappointing results.

Thanks for the advice, I read these a few weeks ago but didn't have time to respond. I did use contact cleaner plastic safe to clean out my cruise button, it wouldn't stay in. Spayed it in and worked the button until it operated properly. I'll need to take it apart and grease it though. Going to do the rear differential oil and coolant change this weekend. I'll tackle the front end another time. I appreciate the advice.
