Frame shock mount : This has happened several times so it is an area you want to pay attention to for periodic inspections. Inspect from underneath bike between rear wheel and engine.

 

 
Rear Wheel Hub:  Pay attention to a faint popping or clicking noise when rolling bike with engine dead. Most will notice it when backing bike 
out of their garage or storage building a faint popping or thud.  These failures are occurring on
low and high mileage wheels.
Although this is just one possible cause,  it is very easy to check for when replacing a rear tire.
Notice the ridge formed inside the drive side of
the hub, this is where one of the 4 wheel bearings
rides in the hub.  In the picture to the right you'll
notice the bearing that is visible, it has also 
wallared out the hub as well.

What to check for:  A pop, click, faint thud when rolling on bike with engine dead as in rolling to a stop or backing the bike out of garage or storage shed, a wheel bearing that falls out when removing rear wheel.

Oil Pump Shaft:  The picture on the left shows the oil pump shaft Yamaha used for the Road Star in models previous to 2002.  The oil pump shafts on the right are the early model.  The one on the left is the new model.  It is a duplicate of the one used in the Warrior.  There have been some reports of early oil pump shafts braking in the thin area at the top, and subsequently causing very serious engine damage due to lack of oil circulation in the engine.  Many dealers are not aware of this problem.

Thanks to Paul Pierce for supplying the picture

Just replace battery, checked all fuses, turn ignition, lights on, gauges activate, neutral. When pressing ignition start lever, i hear clicking noise, nothing else. What could it be? 
 
Thank you.
Oil pump shaft
Written by roadawg, on 08-28-2012 09:45
My 2000 RoadStar is getting a new oil pump shaft. Why? Turns out if you idle your engine too low as to let the engine lobe like a Harley engine, the oil pump shaft does an inadequate job of lubing the engine. On mine, the hydraulic lifters failed and I need a new oil pump. Save yourself the $500 fix and make sure the idle is set correctly. Hope this helps anyone else with this issue.
