Feedback: make sure it's got oil and water (coolant), Check your rear caliper/brake
assembly
Answer: (unknown, not included)
Noise 40: When riding (01 F650GS) 2k miles. I have a rattle coming from the front area around
the headlight or steering head. Rattle is only heard when riding over expansion joints or small
potholes. Have checked various things but cannot find source of rattle. Just afraid something is
going to fall off the bike. dgriffin #1696

Answer: (Unknown, not listed)
Noise 39: I've experienced two occasions where it sounds like the engine (I'm assuming it's the
engine - it may not be) is making a loud "grinding squeal" - that's the best way I can describe it. It
happened once after attempting to start the bike after it stalled and happened again when I was
actually riding on the highway and I was shifting down about to come to a stop. The bike is
relatively new with only 250 miles on it so far. I know the manual says not to "slip the clutch" - I'm
assuming that this means not to use the "friction zone". cheri

Feedback: Wheel bearings (jack up the bike, spin front wheel and listen), front wheel
balance, check torque on the brake caliper mounting bolts, plastic / bodywork, cam chain
tensioner, loose rocks on top side of bash plate...
Solution 1: [ed: someone else with similar noise found it was the windshield] I replaced
the Dakar windscreen with one that does not use the normal mounting points. Riding
offroad a few weeks ago in the Mojave National Preserve I could hear a noise like china
plates banging around. Taking the front end apart I found the problem, there is a wing
shaped piece of sheet metal that was no longer being anchored by the Dakar screen
mounting screws. This part was bouncing around on top of the headlight. Jerrya
Answer: A while back I posted asking what could be rattling around up front on the bike? I
received many answers, but none fixed the problem. I believe that the biggest problem
was the fact that my bash plate and engine guard bolts were loose and after changing the
oil in the bike I got all those bolts tight like they should be. dgriffin #1696
Noise 41: So I'm leaving work yesterday and it sounds like a playing card is clothespinned to my
wheel. The sound goes away by the time I get home. Last night I was heading out to eat and
strange knocking sounds started coming from the bottom end. The knocking slows down as I slow
down. Bangs a couple of more times when I stop. Seems to be from low on the right side.
Generator? Clutch? Crank? Water pump? Fuel pump? I guess I'll find out soon enough. It's a '01
Dakar with 21,000 miles. I have noticed a buzzing noise lately as I pass a wall or something close
on my right side. Almost a chain sound. Troutrider

Answer: I got to work this morning and sat down on the curb and took off the sprocket
cover. While checking everything out I noticed that the chain roller was clunky and
grooves were appearing on it. I've got 10,000 miles on the gold DID chain and it looks
decent. I ordered a new roller assembly. Troutrider
