I have a new 2002 model Yamaha XJ900S Diversion. I've just goten back
into riding after an absence of nearly ten years - except for a dabble
with a trail bike - so I thought my problem was just me getting used to
a road bike again.
I go some weekends with friends up through Mt. Nebo and Mt. Glorious -
for those not familiar with Queensland (Australia), these are twisty
mountain roads just outside of Brisbane. Most weekends you'll see all
the 'Blade and R1 pilots out there pretending (some rather
spectacularly!) to be F1 riders. It's a good run as you can take it
hard or soft depending on your skill and/or daring levels.
I've been through Nebo/Glorious with friends who ride a mixture of
Ducati's, GXR's, 'Blades, R1's, VF's etc. etc. None of these guys are
idiots, most are 'mature' riders who just enjoy the ride and
companionship.
My problem is as follows:
When I go through this 'course' the XJ develops what can only be called
a 'wobble' or a 'shimmy' in the rear. As I said above, I though it was
just me, so I let one of the other guys have a ride and he reported the
same thing... It's a bit disconcerting to be banked over and feel the
rear moving around. It's not the tyre breaking away - I'm not leaning
over far enough for that problem! - it just appears the wheel is
somehow moving around. Boy, this is really hard to explain!
I have checked the air pressure, I've upped the pre-load in the front
forks (as they are way too soft) etc. When I took it into Yamaha they
asked me if I was using it for its intended purpose(!). I retorted that
I would expect a modern bike to go around corners... They could easily
tell I am not a boy racer - 44 years old and, er, weight challenged -
plus the (standard Metzler) tyres certainly haven't been scrubbed to
the edges! The suggestion from the Yamaha mechanic was to increase the
tyre pressures and drop the preload on the rear shock. I tried those
suggestions but haven't yet gone back to Nebo/Glorious. On some bendy
bits near my home it appears to be very marginly better, so I'm not
sure.
Any suggestions? Any other XJ900 riders have the same problem?
Let me re-state one thing: I'm NOT a boy racer. I've ridden a 'Blade
and R1 and sure know how well they handle because they are dedicated
scratchers toys - it's just that I'd expect a bit better from the
sports/tourer XJ900.
> Any suggestions? Any other XJ900 riders have the same problem?
Hm. Well, my Divvie isn't the world's greatest handler, but that's not
why I bought it.
Hard to say without knowing what the roads are like and how fast you're
attacking them. It's possible to get the Divvie wobbling and pitching at
90-100mph on some bends.
Buy a Ducati (see sig!) and/or slow down.

First of all, sorry for my english, my native language is Dutch.
I think your problem is the standard Yamaha spring in the front fork.
In the fork, Yamaha put a spring that don't have the complete lenght of the
fork.
To compensate the rest, they put a tube in place.
When you drive with that spring over small roughness, it feel's like your
wheel slide for a short thime.
In Belgium, a lot off Diversion driver change the standard Yamaha spring
into a White Power spring.
It's easy to change and not so pricey (120?) and feel's a lot better.
I hope you can do something with this.
so long

Float the rear wheel in midair ala with a center stand (NOT a
swingarm stand) and Grab the rear tire and brace yourself against the
frame. Give it a tug and look for play in the rear wheel vs the
frame. Could be in the swingarm pivot or in the rear axle or in the
suspension link. This is not a common problem, and not unheard of
either . But you won't find it unless you look for it. Just one more
thing to eliminate.. .

wrong bike for the road. it has a hinged frame and swings in
the breeze. you need a real sportbike for that road.
don't waste money trying to mod your bike.

Wear in a suspension link won't show up in play in the rear wheel, you
berk.
Harsh but fair. Stiffening up the forks and replacing the rear shock is
the best you can hope for.
I hope you read aus.moto then ... I can't be bothered with the
wankers in the other ones (I'll stick with the wankers I know!)

First things first: have you checked all the rear wheel bearings,
including the shaft drive bearings and the swingarm bearings?
Check the front ones too, just in case ... 0.5mm of movement
at either end is plenty enough to feel ...
-----sharks
I'd probably string-line it first to make sure it's straight and give
things a shake to make sure there's nothing loose.
I'd also get someone who's used to that kind of bike to give it a run
(your mates might be comparing it to their R1s) but it sounds like a
wrong-profile back tyre to me [or flat, but you say the pressure's
OK.]
Wim's suggestion about the fork-springs sounds good (although a little
extreme).
Whereabouts in Brissie are you? I'm at Carseldine and I know a fair
bit about the XJ900N but I've never ridden a Divvy.
Good luck ....... Clem
Had the wheels rebalanced?? checked wheel bearings, steering head
bearings arent a little loose?
The front wheel isnt actually bent is it? prop up bike spin front
wheel while holding screwdriver on fork leg pointing at rim, and see
if it is straight.....
FWIW, have a really good look at the front tire condition and
pressure, the steering head bearings and the front wheel bearings.
Very often, a problem at one end of the bike (such as a back-end
wallowing) is caused by a problem at the other end of the bike.

What speed? high speed corners or low-mid speed(legal)
BMW K100s can suffer from this too on high speed corners, in their
case it was the back shock had insufficient damping, put a decent rear
shock on and no more wobble. BTW the weave/wobble never developed
into anything dangerous, but it didnt make you feel confident.

That it certainly is. I didn't think the US got the XJ900S - this isn't
the XJ900F Seca from the 1980s, remember. Although it is in a very
similar mould.

Nice. I've got my Duke for that sort of stuff.
Have you ever ridden one?
In article <2O5M9.102416$%A6.10...@news.easynews.com>,
I agree with the other comments on front suspension springs. It's on my
books for the next improvement but it doesn't affect the handling for my
style of riding.
Go see Tyres for Bikes up in Albion.

Heh, what a good site. Bookmarked, so thanks for that
Funnily enough, I've been ruminating about buying an SR500 myself
recently. They're fairly scarce in britain, but they sold *zillions* of
them on the Continent, and it remained on sale right up to the late
1990s in France and Germany, believe it or not.
One of these days I might pop over the Channel and try and rootle one
out.

Legal-type speeds. I'm not a boy racer.

" didn't make you feel confident" is exactly the feeling I get. It's
only a mild problem but it saps your confidence.
Nah, my panties are quite comfortable, but thanks for asking. ;-)
Just wanted to know if you had actually ridden an XJ900 is all.

Fitting a BT45 on the front did wonders for the handling of my bike as well.
It is just about the only non-touring biased tyre you can buy at that size.

The good news is the Yamaha dealership has finally agreed for me to
bring the Diversion in early next week and have each and every member
of their Service Department take it for a ride. Hopefully they will be
able to find the problem - or do a group denial (!)

Now below follows the text of an email I've just received from one of
the truly tragic, anal, ignorant, sad little fucks that seem to infest
usenet.

True. I can't even figure out what the "disparaging remarks" are
supposed to be. I can only assume that while almost all Aussies, most
Brits, and many Yanks, have a sense of humour, to post on
alt.motorcycles.yamaha you must first prove that it's been surgically
removed.

Some of the nicest people ride Yamaha's so I am told.

I think what it is, actually, is that Americans (and I know I'm
generalising here) find it very hard to determine that "piss-taking" (as
prcticed constantly by Brits, and to great effect by Aussies) is not
malicious and is entirely good-humoured.
The gentle interchange of mock-serious insults as a means of affection
seems to be something rather alien to them.
This is one reason why Brits tend not to use emoticons so much - it's
usually possible to infer, just from the "feel" of a posting whether
someone is actually insulting you, or merely "taking the piss".
> do you want sr pictures?
No thanks. It would only make me envious. But you *have* rekindled the
desire to own a decen big single.

Not sure.. I'll enquire...
Britain is the nation and of course the Welsh and Scottish complain if you DON'T
include them, all-encompassing, in references to such. I'll be seeing a Welsh
boy in 45mins so I'll ask him then...
paulh
Does it work? Well... I took it up Mt. Nebo and Mt. Glorious on the
weekend and it was far more manageable - to the extent that I was able
to make a decent fist of keeping up with my mates on the FireBlade and
VTR-SP1. It also helps that having the bike a bit more stable I was
able to concentrate and see that I was often in a higher gear than
required for many of the corners. This was probably compensating for my
nervousness with the back end.
The guys FireBlade and VTR-SP1 are not too fast, and more importantly
know their limits - unlike the guy who crashed his R1(?) and absolutely
destroyed it. We came across the blackened blob, with flames and smoke
billowing out of it, lying in the middle of the road. The rider was
lying on the side of the road with some of his mates looking after him.
Thatšs the second serious crash wešve come across in the last two
weeks!
Anyway, I digress! We donšt ride anywhere near as fast as some of these
crazy pilots. Išm just happy to have the XJ handling better and able to
do some sports riding without feeling like the back end is up to
tricks. As it is, when the standard tyre wears a bit further Išll
probably replace it with a more sportier (sticky!) tyre, as I will not
be doing any real touring in the foreseeable future.
At least until I can afford a set of pannniers... but thatšs another
story!
