Does the 1300 have a high speed wobble? I thought that was an 1100 thing.
I thought it was only a 1300 thing. I understand that most Police forces were very happy with their 1100 Pans but were seriously disappointed with the 1300 replacements, hence very few (if any?) still using Pans.
My limited testing suggests 1300s wobble from about 95 & 1100s from about 135. Unless you remove the topbox which stops the 1100 wobbling at all.
That would be about right then as plod bikes are "sans" topbox.

The fireblade's fuelling when engine braking.

Lift off the throttle and let it slow down using the engine. At around 40 mph it starts to decelerate less than before. No idea why. Nobody has ever commented on the same thing to me.

So for example i'm coming up to a roundabout. Off the gas, down to 2nd/3rd. Brake, then rely on engine braking as i'm leaning it left and then right to take the line around the roundabout. It's lined up just right. At current engine braking i'll be happy with that speed. Then suddenly it stops decelerating by as much and i have to put in a dab of brake to bring it back.

fking annoying!!!! I'm fed up with running wide on corner entry because the engine won't decelerate the bike consistently!!!!!!

It was new in June, and i mentioned it to the dealer but was met with shrugged shoulders.

Shouldn't be a problem as by the time you're on the roundabout, your braking/deceleration should have been completed and you should be either accelerating or holding a steady speed! Perhaps you need to replace the nut on the handlebars! wink

lol. possibly. silly

Any time i'm off the throttle tipping it into a corner it does it, just before i pick up the throttle again. But only at a certain speed.

Same thing when coasting into 30/40 limits. Brake a bit then roll off thinking i'll be about right when i enter the speed limit. Then the bloody thing decelerates less!

Sounds like the fuelling is coming back on to 'idle'? How fast is the idle set? maybe shift down another gear to keep the revs up...

No idea. It's a 2014 bike so should be perfect. It isn't related to gear or revs. It does it at about 40mph regardless

I'm not disputing that. It definitely does it. And it definitely does my head in. Hence my post.

I have heard stories of the 1300 weaving from as little as 80mph, but there must have been something seriously wrong there.

Here's mine, some years ago in Germany, demonstrating that 130mph seems to be the point where it's pretty well guaranteed to wobble...

Honda went to quite some lengths to identify the problem but never really fixed it; they tried changing torque settings, changing the order bolts were tightened, fitted rubber flaps inside the frame to change the airflow through it, altered some of the fairing parts to allow air to escape etc. etc.
In my experience it depends on tyre type, wear and pressure, whether you have panniers and/or topbox fitted, whether you're carrying a pillion, where the screen is set, whether you're a fat git and probably what colour undies you have on. There seems to be no one cause of it... but most people don't crash as a result, unlike two Police officers whose incidents caused ACPO to advise all forces to remove them from Police service (and as said by another poster, some had their frames chopped about so they couldn't be returned to the road).
Interestingly I have seen them still in Military Police service, but then maybe they never need to go over convoy escort speed.
My bike has had its rear spring changed to a Hyperpro (still weaves), the back tyre changed for a wider one (still weaves) and mates who've ridden it report that it weaves for them too, although I usually can't catch them to witness it biggrin

Found out today that removing the spark plugs on my Thunderace is a PITA job to do involving removing the radiator. Certainly not looking forward to doing that in the next few weeks.

You'll be removing the rad to fit the exhaust anyway? Its not that difficult really, once you have removed the fairing, tank, coils, air box, radiator etc etc :he he:

I will be removing it to do the exhaust but thought I could get some of the smaller jobs I need to do out of the way. Apparently even once the rad is out of the way, it's still awkward to access. I thought Id avoided awkward spark plugs when the VFR got smashed up!

Happily though, the bike is clean and there are no bodges found so far despite the tatty fairings.

My Tornado did this until I disabled fuel cut by grounding an ECU wire. On the overrun above the certain RPM pretty much all newish bikes will cut fuel likes cars have done for a long time, but when you hit the RPM threshold and fuel starts being injected again engine braking is reduced.

It was yours I felt starting to weave very slightly at 95. Not enough to unsettle it, just enough so it didn't feel rock steady.

Corrosion! st paint finishes and shoddy materials.
Don't have a garage any more so given up riding as I'm fed up of the constant maintenance.
