Since the weather's been so nice here in Northeastern Ohio, I've
parked my car and have been riding the Ambo everywhere for the last 2
weeks. I've noticed what sounds like a dry bearing going south coming
from the front of the generator, kind of a squeeky squealy rolly noise,
only after the engine's warmed up, and it has concerned me also.
The generator bearings on my wife's Ambo seized up several years ago
among much squealing and smoke. I cut what was left of the belt off and
made it home easily on the sparks made by the battery.
Now I can't remember if you can get to the front bearing to lube it,
which would probably quiet it down. Has anyone been able to do this? As
an aside, tightening the belt too much will put an additional side load
on the gen bearing and hasten its demise.
Rick mentioned taking off the belt and see what happens, great
idea. Warm up the bike first if that's when the noise starts. Turn the
generator by hand and see what that feels/sounds like.

| You know, I am beginning to suspect the generator. I took off the front last night and my belt was too loose (rubber dust all over the place) so I removed a plate to tighten the belt a bit thinking that would fix the problem but it didn't. It is a very metallic sounding noise. I am assuming the generator has bearings? If so I suspect they might be in need of repair. One other thing I didn't mention before is the noise doesn't start until after the bike has warmed up a bit. Ted |
