Cams gone and option to get another bike?

[beaver]

This is an interesting one, my cams were done on my 67 plate, 7.5k new ro me GS. So when BMW sent me their 'how did we do' form, I put it all down as to how disgusted I was that a bike with this low miles needed new cams.

Anyway, work done and working fine now
But I did get at the dealer a bit, saying how can they do a 150 point check and a service and not see the problem.

So got a call from Louise at AJs asking me what I wanted to do

I explained that the bits of old cam going around the engine and box made me nervous for the bikes longevity. So she offered to get me onto another bike, similar spec, miles....
What do you guys think?

1. Will cam bits be embedded in the engine? Filter take out 20um but most damage is done by 10 to 15um bit that could get through. Also, I guess the gearbox is splash feed... so could bigger bits of got in these bearings?

2. Is it better to keep this one as I now know the cams are ok?.. dont want to be out the frying pan into the fire.

Anyone had longer term issues from a bike where the cams were changed??

 

[Tractors are go]

At least aj are attempting to resolve it for you.

Personally, I'd be asking the mothership for a replacement engine.

Im thinking either new engine or change the bike. Not so sure id be happy with just replacement cams. As you say, where have all the metal fragment’s gone ? Your choice at the end of the day.

Ask Louise if you can go and have a good test of the other bike first, then if happy get the other bike, and you will have 2 year warranty, I would hate to think about metal bits in any engine over time, look at the amount of wetheads on the road, not many have had cam failures, just my egg and cress moment.

getting onto another bike could bring its own issues, it's probably fine but I get your concerns.

I would suggest a free service to flush the engine again and push for extended warranty, beyond the standard 2yrs

 

[spoonz]

I would go new engine if poss or an extended warranty on yours should the engine have more issues although I doubt it will. People may remember Ducati and Honda had issues with flaking cam lobes and it never had any reported knock on affects. Some of those models are still going strong all these years on.

How about a new bike and a massive discount? It worked in my case...

Ah, Beaves Baby , we have similar threads!

I also wory about the small bits that may create havoc. It`s only my opinion but case hardening peeling off the camshafts might be my problem too (engine only done 6K) however I stress it won`t be rectified for another couple of weeks or so.

If it was me I`d go for the (fantastic) suggestion of an engine flush followed by new oil and filter, hopefully making sure that there`s not pain for you outside of warranty.

Also, you may consider asking for either a) something in writing that says that for the life of the engine it`s guaranteed should any failure result from said bits knackering the engine or if they don`t feel willing to do that b) a replacement engine.

I`m told that legally you are actually allowed to do this but I can`t say for sure.

Whatever happens I do hope you get it sorted.

as a side note, if the bikes are like the cars, then "louise" will get paid based on the number of 5-star reviews she gets on that "tell us how we did" email - so if she does sort you out one way or another, then give her the 5-star review so she can put food on the table again.

 

[beaver]

Interesting replies guy's.. I was thinking of living with it and see how it goes.. they are doing a free 12K service and on replacing the cams they did a full flush etc .. but its the damage done already that may come out longer term that i'm concerned about....
A new engine would be one way to go for sure... they could help me onto a 1250 but does that come with its own risks?
Or swap out... but I think one way or another, I don't want to keep the engine I have now longer term.

I'll see what they say.. or as suggested, they can underwrite the engine for 5 years say??..

 

[vincentrapide]

I had a camshaft fail at 700 miles on an S1000R and held out for a new bike. Bmw’s initial offer was “we’ll change the oil and renew cams and followers”. Based on experience of rebuilding failed industrial diesels and witnessing the resultant spread of debris, I wouldn’t settle for that.
Good luck with your efforts.

 

[Woland]

If it was me I'd probably be satisfied with extended warranty. If there is a problem with debris remaining in the engine it will probably make it self known relatively soon and not at say 60k miles. A hefty discount on a 1250 would also entice me...

By some accounts there are some 1250s out there with similar issues

Yes, I know of about 4 now where the cams are issues... how poor is that of BMW.. not only to have the problem on 2013 through to 2018 models, but now to have it on the new shit-cam also.

 

[steadysteve]

I think you wouldn't be asking the question on here if you would be happy with the existing bike...

 

[roamer]

A replacement bike new or used might be better from a peace of mind point of view, as said you aren't asking the question if you were happy to keep it,
There are a few major items now with quality issues on the Lc bikes, pity they ride so well,,

4 out of however many thousand isn't a bad mtbf, my concern is more the timescale of failures. All appear to be very low mileage irrespective of age, this suggest rather than a faulty batch of shafts, for example, it is more likely a design/owner fault which is a more serious problem.

Interested to know, how could it be an owner fault ? Please explain as I’m so thick I don’t understand your reasoning

4 that he knows about - who knows how many actually have this issue

If it was a design fault there would be far more failing and no idea how it could be an owner fault.

Most likely a bad batch of cams.

Leaving thing on the side stand for sometime. Which way will the oil drain, which side has problems?

Owners do mirriad of little things that testers don't.

In preproduction testing of Honda V4 they never had a single cam failure; why, because they didn't ride bike until cooling fan cut in, engine was at operating temp.

With 2d dash it shows recommended rev limit and flashes all leds if you exceed it, you'll be surprised how long it can take for bike to go, ok now you can start making me work.
