Divvy with a massive vibration problem

[Nobby the Bastard]

A mate has a Diversion that's less than a year old, hasn't been ridden a massive amount (fair-weather...), but she was complaining about it vibrating yesterday.

I said that if it's at about 4-5K, all 4 cylinder in-lines seem to suffer with that, just avoid that rev range or get it though there into the fun zone as soon as possible.

She said it wasn't there, it was all the way up the rev range, getting worse with engine speed. She describes the results of a 5 minute ride as causing her fingers to tingle afterwards, which sounds like the beginning of 'White finger' to me...

Obviously, I've told her to take it back to the dealer that sold it to her, tell them it's fucked and to either fix it or replace with a new one.

Now, I know that Divvys have rubber engine mounts that can degrade and engine mounts cn fail or be loose, causing vibration, but I can't really see that a one year old bike with a sraight four engine would produce that much vibration unless something was really knackered in the engine.

Anybody have any ideas of possible causes that she can suggest to the dealer so that she doesn't look completedly mechanically ignorant, and thus lessen the chances of her being fobbed off?

Check ALL the engine mounting bolts for tightness !.

I'm not going to start fucking about with a bike that's still got 2 years warrenty.

She takes it to the dealer, explains it seems to have a bad vibration and can they please take it for ride and see what the problem is, it is not her job to be doing the diagnosis.

[Nobby the Bastard]

Does anybody actually read the post before posting?

That's two people now repeated what I've said without adding anything useful.

Didn't you see the bit about WARRENTY?

How does a wallet come into it?

On behalf of everyone in this thread that you have insulted.....

I take your point about my attitude. Please see my sig...

Let me tell you a story about dealers.

My other half taking her car to a dealer for about a year and a half for them to 'try' and fix a problem with the knocking at the back end of her car. Then she met me and told me about it. Two days later (the internet is a wonderful thing) I'd found the problem and two weeks later I'd fitted the parts that Fiat had designed to solve the problem.

It's not un-known for dealers to try and fob people off where warranties are involved. I'm just trying to educate her as to possible causes so that IF they do, she can say 'No it's not normal, it's more likely to be Blah, blah, blah....)

Maybe I should have just asked 'What would make a Divvy vibrate at all engine speeds, getting worse as the engine gets faster' rather than giving the back story....

is there any oil in the damned thing? that is something warranty will not cover.

My job is a fun job. It is one where I get to investigate problems in complex equipment, and attempt to resolve them. Invariably one of my 'cases' starts with an issue. "The equipment is not doing what it should."

The next question is invariably: "Do you have any idea what could cause this?"

The answer is yes I probably do, but it could be one of many things. I'm not in the habit of guessing. If I guess then it makes me look bad, it doesn't necessarily fix the problem and it can waste time, money and can even make the problem worse. So, what do I need to turn no idea what is going on, into at least some idea?

Evidence. I need evidence on the issue. I can do this in a number of ways. I can ask for log files, I can ask for configuration data, and I can ask the customer to perform a test and tell me the result. If I get none of these things, then I cannot continue my investigation. Which brings me to the subject of my post.

Why in the name of everything that is sacred would you not want to check to see if the engine mounting bolts on your friends bike are tight? It's not going to do any damage, it will not invalidate the warranty and it might help to resolve the issue. If you do not provide us with any evidence on the issue, we cannot diagnose it. In the same way, if you refuse to present the bike to a dealer you cannot know what they will say. It's like Schroedingers cat. Until you open the box you won't know if the cat is dead or alive.

So, in this case you have two choices if you want to resolve the issue. You can read the suggestions on here and try the sensible test that has been suggested, or you can take the bike to a dealer to check over.

Alternatively, If you do not want the issue resolved, then you can merely describe the issue on here very vaguely, ask for answers, not provide any evidence, and refuse to take the bike to a dealer.

Is that a hard concept to understand?

(P.S. Genuine post, not plagiarised from a wiki because I can actually read, write, investigate, experiment, calculate, extrapolate and understand.)

Just to be clear, I made no mention of 'dealers are wankers' when speaking to her and I'll ensure that I don't when I go back with any suggestions.

It's not the wheels or chain, it vibrates when stationary.

Clearances or cam chain- possible but it's very low mileage.

Oil - possible but she lubes the chain before every ride and said that the limit of her mechanical prowess was chaining the oil, so unlikely. I'll suggests that she checks herself though before taking it in.

She lives a long way from me, I don't really know her that well, and i used the word friend instead of colleague.

But your point is valid.

another suggestion would be to check the front sprocket mounting nut on the final drive for tightness, these caused massive problems when they worked loose on the 600 thundercat and fazer models causing vibration and the need to strip the whole engine to replace the output shaft. (very expensive)

Does your mate know it isn't like a moped and has more than one gear? Riding around in first is bound to give someone whitefinger after a while.
