Got me a new one

[Laverda Dave]

From the interweb......
Honda has initiated a global recall for affected CB1000 Hornet and SP models to address excessive oil consumption caused by out-of-specification pistons and piston rings. The manufacturer is implementing a permanent fix by replacing the faulty pistons and piston rings to resolve the issue.Affected riders are being contacted directly by local dealerships to arrange for the corrective engine service

It would be interesting to know what they actually replace...... you see, in the early parts of this story, I read it was incorrect honing of the cylinder bores..... so, I wonder if they're replacing the barrels at the same time as new pistons and rings.

I am kinda disappointed in this...... was hoping the bike would make it to North America very soon.  Usually it's a year or two delayed intro here, so I suppose by then all should be sorted out.

What was your ‘source’ Dave.

Google, I asked the question 'How are Honda rectifying the 1000 Hornet engine oil consumption issues' and that was the answer. I had heard the same thing on a youtube post a few weeks ago.
Of course the information a manufacturer releases to the press can differ from real life, just ask KTM who blamed the owners of their bikes for the terrible cam wear that was proved to be the result of poor design, manufacture and QA of the parts and still they denied it.
From what people are saying on Pistonheads it would appear Honda Japan are maybe failing to get the message across to Honda UK. If Honda fail to act and address this issue quickly their reputation will only go one way.
If it is down to pistons and rings that would be very bad news considering Mr Honda himself made his name making piston rings in the 1940's/50's and founded the Honda company as a result.
As an aside, where is the 1000 Hornet engine made? You never know these days as motorcycle manufacture is so global along with everything else, for instance I thought the new Norton V4 engine was UK manufactured but no, it's made in India. Back in the day of the old Norton V4 (Stuart Garner era) I was told the engine was designed in the UK but made in China along with the never to be seen Atlas 650 motor.
When you consider how engine design and manufacture has evolved since the days of rattly 500/750 twins and the level of sophistication where it is now it only takes a bad batch of something to bring it all down and especially as news travels so fast these days. Back in the late 70's I used to take a litre of oil with me when out on my 250CSR Matchless, it would burn through or throw out 1/2 litre every 100 miles!

Worst oil consuming Honda i rode was a Black 750 F2 that on the way to I.O.M was using 1 pint every 350 miles, over there it dropped to 1 pint every 250 miles so i brought it home early(shop bike) pulled it expecting shattered rings and destroyed pistons, nopeso pulled head apart and found 4 worn out exhaust guides with 1 destroyed stem seal, mileage from memory about 20,000 aged about 2 years

The F2’s had a bit of a reputation didn't they Bryan. Wasn't it down to Honda changing the valve angle in order to fit bigger valves and try to keep up with Suzuki and their dohc 750? All the Honda engineers and designers had been seconded to the car division leaving the old 750 languishing with little or no ongoing development. The changed valve angle put a strain on the valve train as well. The F2 was nothing more than a stop gap until the dohc KZ750 was ready (and the CB900).

Yes Dave, plus a change of guide material away from hard stellite, i think.
Some lasted 30-40,000 others only 15.
I went round on mad sunday and it wouldnt pull 100mph so i rolled of from top of mountain to the pub a nd leftvthe poor copper at the pub, where it goes back to two way, in the biggest cloud of shitty blue smoke ever seen and cheers from the spectators!
