"Understeering" on a motorbike

[Mr Moofo]

I'd say it was a pragmatic and perfectly safe solution to a pressing problem. Today I plugged a car tyre with a mushroom plug and I'm very happy with it. I'm guessing they will also use tyre vulcanising liquid, so you'll have a pemanent solution. There's an awful lot of unnecessary drama surrounding tyre plugs - done right they're as safe as a new tyre. Your tyre place wouldn't have offered if there was any chance of comeback on them.

Indeed - and that is what they said.
The puncture is clean - and on the centre line - so no wall damage etc. It will be plugged from the inside (obviously)

[Mr Moofo]

But that's irrelevant here. The point seems to be that the bike needs more effort - whether because of geometry, tyres, whatever - than the OP finds comfortable.

It wasn't I felt "uncomfortable with" but "I noticed it" - hence tried to work out the difference - and it is mainly on something tight like a roundabout.

I've just clocked what bike it is.

I think certain expectations need to be set when comparing turn in on a Triumph Scrambler and a Ducati Diavel...

TBH, it is an old Speedy - '95 not the new one.
The Ducati Diavel, when making progress will actually out handle both of them ... and why I am not trying to analyse what I am trying to do, and just looking at where I want to go

To be fair, you said:

it just doesn't quite want to go where I want it to

And you had already identified the solution:

a bit more leverage)

Impact wrench now bought to try and get the rear wheel nut off the bike. Ducati setting is 220 nm. A big breaker bar and a length of scaffold pipe have not made it move at all

[A_morti]

That's a lot of ugga duggas!

Just in case... There's not a grub screw, e-clip, or cotter pin that you've missed, is there? 160ft-lb is toit, but a long enough bar should do it if you can have someone sit on the bike and jam the rear brake on while you lean on it.

[Mr. Dazzle]

Looks like there definitely is one, but it also looks like it's pretty obvious so I'd guess the OP has seen it!

Besides, you'd not get the socket on there with the clip in place?

The was a spring clip that holds it all together - just in case the arsehole in the Ducati polo shirt hasn't torqued it way beyond spec....
I spotted that and did check three times to see that there was nothing else.

You won’t go wrong with an impact wrench as it will come in handy many times over.

I haven’t read the whole thread but I’m guessing you tried the trusty in gear, someone on the rear brake and big fuck off breaker bar method? That’s how I used to get the 1299 rear wheel off

Single sided swingarm (SSSA) problems. You don't get that nonsense on a bike with a conventional swingarm.

[Mr. Dazzle]

VFR solution of 4 bolts like a car always seemed more sensible to me.

Speaking of cars - I know I've mentioned this before on here, but it still makes me laugh. My old boss' Porsche 911 had single nut 'centre lock' wheels with a fancy socket to undo them. Said socket had a cubby hole under the bonnet to hold it so you'd always have it with you. That's great and everything, but the wheels are done up to 450Nm so no bugger is getting them off at the side of the road anyway! I also bet the Porsche dealership and every tyre fitter nearby has one of the sockets they forgot to put back in a customer's car anyway.

Wouldn't the RAC/AA be able to use it if you called them out?

Completely agree, but the visual impact of a fuck-off fancy single castellated nut trumps the VFR's sensible approach every time. So if you can't get the wheel off at the side of the road what's the point of a SSSA anyway?

[Mr. Dazzle]

Wouldn't the RAC/AA be able to use it if you called them out?

On paper yes, but the OP is struggling to undo something done up half as tight....

AFAIK 450Nm is right up on the limit of what a leccy dugga dugga can dug. Do RAC vans have air ones? I dunno.

BTW air powered ones? *chefs finger kiss*

Looks cool.

It's not a backward thread is it.

Air windy guns can only work as well as the compressor supplying them. You need a really hefty compressor to loosen nuts done up to 450Nm, let alone above that. And an RAC/AA van wouldn't have space or payload for one of them. They'll be using cordless leccy windy guns, for sure.

Yeah. And that's their sole virtue. IMHO, of course...

They are mostly confined to the 'Politics' section.

[Mr. Dazzle]

It's interesting to me to note that the two bikes I can think of which have a "legitimate" claim to needing a SSSA both do it sensibly.

The 'racing type' VFRs have a single nut so you can change the wheel quickly in a pit stop. They're also only ever going to be worked on by men with fancy tools. 'Road type' VFRs use 4 bolt hubs normal tools work on.

BMW GSs which might need to change their wheels out in the middle of nowhere use 5 bolt hubs you can undo using a small portable toolkit.

Far be it from me to suggest Ducati aren't doing it sensibly

I originally hand it go the Ducati Stand , with the bar through the wheel.
A quick chat with a Ducati mechanic suggested in gear, person on stop, stomping in the back brake, Plus-gas left for 15 mins, hair dryer to speed up flow.
Then big breaker bar or impact wrench.

A breaker bar worked the last time I did it - but it has been into the Ducati Technicians since then

[wull]

What impact wrench did you buy? What’s the spec on it? NM?

I use them for stripping down engines and they’re worth their weight in gold.

[mangocrazy]

Best value impact wrench I've found was an Aldi/Lidl cheapie. It was a mains corded gun, but beats my Clarke mains impact wrench all ends up and cost less than £30. Even came with 4 impact sockets and a carry case. I know most folk go for a cordless wrench, but unless you're using them regularly I'd prefer corded. It's a bummer finding out your expensive cordless gun's batteries have died through lack of use.
