Help me fellows. I found two weird noises from my 1997 Divvy. First one comes from the front of the bike. The bike sometimes clatter when I drive on rough surface. A guy from Yamaha dealership said that it is common problem with older Yamaha's. He said that the pipes from suspension is banging against itself. Do I make myself clear?  The second noise is a high pitching buzzing sound. It happens when I rew the engine above 6500 or 7000 rpm. It sounds like something is loose, but I can't find the source. Is there anyone out there who can help me? |

I used to get a buzzing from the fairing on my 96 D9, finding where from exactly took a lot of time, wasn't a real problem just annoying.
The clatter, not sure what he means by pipes from suspension. If it's a click then check the bearings on wheels and headstock.

I usually speak Finnish so it's a bit hard to explain the sound from the front suspension in English. Wheel bearings have been changed last summer, but I have to check headstock bearings
I know about the sound from the fairing and I have cured that. I think it's something else. Could valves do that?
Bike runs great and handles as well. I just want to get rid of unusual noises.

I know English isn't your first language. Your English is still as good as some of the native speakers.  I don't think the valves will only make a click on rough ground so you're most likely looking for something worn or loose. If the headstock is OK, mine started to click at around 20,000 miles, then start looking for something loose. My headlight also worked loose after a day riding up single track roads. The fairing came loose after I parked it on its side.  It's a Divvy, if there are no unusual noises it's parked up in the garage. ;D |

Mine does a soft clunk as the power takes up. I thought there was a gearbox problem but it stopped after I greased the rear suspension linkage. It was back again after a few miles, so I really should fit a set of needle roller bearings.
Fairing rattle noise is usually easy to find by the rubbed paint. I stuck some strips of Duck Tape along the inside edges of the top panels and into the groove of the lower panel. The noise stopped at least for now.

I have cured the fairing rattle few years ago and the bike is ok for that. The clatter sound is coming from the front of the bike and is heard when I drive on gravel or similar rough surface.
High pitching buzz is heard when revving the engine above 6500rpm.

I had a knock from the forks when the font end hit a ridge or sharp bump. It went away after I changed the oil - might that be it?

Another thought - is the rubber cushion for the centre stand still on the bike?

The rubber cushion is in its place and I changed the centre stand springs last summer. Maybe I change the oils and see what happends. Any thoughts what sort of oil should I put in to make it stiffer?

I put 15W in mine.

I had mine changed today. 20W and new progressive springs. Then again, I'm a big lad.
Regardless of what weight of oil you choose, new oil is a Very Good Thing as fork oil loses its viscosity and therefore its damping ability over the course of time.

Brilliant. Handles so much better.

Doubt if you're a bigger lad than me. tried 20W but found it too stiff. Went back to 15W. With 20W in the MOT tester reckoned it was borderline fail. I pointed out that was debateable, he said he fills in the pass sheet so it's his opinion that counts, argument lost. ;D |

6'4 and a whisker under 20st  The true handling will only come in when the tyres get changed, but I'm really liking it so far. Much more positive steering input. If it fails MOT because of it then it'll go straight back to firefox for a free change; it's under guarantee. The head honcho gave it a good test after the service and said that the sag was "bang on". |

 Maybe it's just my style of riding, but I much prefer this setup, even if it's still slightly "overstiff" compared to the norm. I'll let the whole lot bed in for a few weeks and then maybe decrease the preload. |

Yep, just a tiddler Bear.
I spoke to Reaper the guru on these matters & we settled on a 10/15w mix (well he told me really ;D).
Bike always feels better when you do something like that.

High pitching buzz is heard when revving the engine above 6500rpm. The buzz, I'm not sure. The clatter could be loose brake pads in the calipers if you only hear it on gravelly or rough roads.....? Mine makes noises only over the local town's pretty cobbled strips in the road surface! |

It could be the fork slider bushes that sit below the slider seals. There's a recent thread on that.
It could also be the steering head bearings. Its amazing how much they can deteriorate before you notice something is wrong.

Hello I was browsing and found your answer here Pilgrim. I'am having exact issue you mention. That rattle noise from front brake pads. As I found, the "jaw" (or is the right word caliper? the thing holding pads together) is loose. Not only it is going left and right a bit, but also back and forth. Whenever driving over something bumpy I hear it. Friend told me left and right is normal, but not so much in every direction as mine go. Trying to fix this, if any useful info lying somewhere on the forum I would appreciate to point me in the right direction.

Yesterday I changed the front brake pads and the antirattle pin. I also tightened some bolts. All the extra noises were gone. Funny how silent the divvy really is... ;D
