Help - whining and it's not the kids

[noddy]

Hi All

I've got a whining noise since my bike was serviced.  It happens at speed and is much worse under load.  Hard acceleration around 70 is the worst.  I've had my bike for 4 years and 20000 miles so I know what it should sound like.

I've just had it serviced at a Honda dealer.  I also had new tyres.  They didn't do a good job:
1) Broke the driveshaft oil plug when inspecting the level
2) Scratched the exhaust heat shield when replacing the tyres
3) Front tyre at 30PSI when I got home

What else could they have got wrong to make the bike whine?  I've checked the driveshaft oil level and it looks good.  Up to the edge on the side stand.
I think I'll do my own servicing from now on!!

I wouldnt mess about -you need a professional to check it over -and if necessary to make a claim against the dealer.Not a time for you to DIY
Years ago i bought a bike privately that the guy had got from a dealer -low mileage it was described as.Reading the service history, the MOT mileage wasn't consistant - I contacted the dealer and asked for the makers service records -it was a Suzuki.He told me that model wasn't on the 'puter as too old but when I asked about the mileage discrepancy he said he know the bike and it was high mileage.I hardly had to mention "Trading Standards" before he agreed to a full refund to the chap I bought it off -he paid me for my bike and we were all happy.
a main dealer will be anxious to maintain his reputation - once you say that an independent expert will be submitting a detailed report i expect you will get it sorted before you have to explain it all to your local newspaper!

Whats the situation with the drive shaft in the CT, I used to have a VFR1200f a long time ago and seem to remember there was a recall for a drive shaft issue on certain production years? Not sure if that ever applied to the CT though.
Did they just check the final drive oil level or change it? If they changed it did they use the right sort of oil.
Have you lifted the wheels up and check for brake binding?
Any chance the different tyres could be causing the change in road noise? Wheels correctly tightened?

Does it sound like the noise in my post: https://www.crosstourer.com/index.php/topic,8884.msg82569.html#msg82569

Mine is intermittent and I haven't got to the bottom of it yet.  I had changed the driveshaft oil just before i went on my trip.

My initial thought is tyre noise, ran several different tyres on my CTs Anakee 3s made a hell of a noise, others nothing.
My GS has Bridgestone A41 and the front is very whiney.

All that said, with the obvious incompetence of the dealer I’d get the bike checked over.

hope the haven't let anything fall into the driveshaft, like  a bit of broken thread from the oil cap which you say they had destroyed.

Thanks for your comments. I've had Michelin PR5 fitted which I had before and I've not heard this noise before. The driveshaft recall was done before I got the bike.

After a 25 mile run at 70 MPH the drive shaft was quite warm. I could hold my hand on it but it was toasty. Since I've never checked my drive shaft temperature before could someone comment on how hot it should get?

I think I'll take it back to the dealer and get it looked at.

The bike was running really great before I spent all this money on it!

Hope they’ve refilled the final drive?
