How old is too old anyway?

Hi folks. So I have almost 80k km (7 years of service, regular maintenance) on my 1078 and some persons start to gently remind me that I'm due for some major engine problems. So I'd like to know if anyone's ridden their 1078s for longer and whether they had any problems due to age. I've never ridden it aggressively, preferring to go under 7k, no sudden accelerations or anything of the sort. Mostly just relaxed city riding and long hauls. So far it's still going good, as good as when it was new.

Question number two is those same guys recommend I change the timing chain. Again, just due to sheer age, not because they ever looked inside the engine to see if it's worn out. MV reportedly provides two types - one already complete, closed, which necessitates taking the engine apart completely (expensive!) and there's another one that you close/complete yourself like a drive chain. And the latter is apparently something nobody recommends, however since MV does make one, does it mean it's as good as the closed one? I mean, they've made tests and stuff, right? But generally I wonder if it's all just paranoia at the moment and whether I should even bother with any of that.

Hi mate I don't know much about maintenance but I am an old fucker who says 'if it's not broke don't fix it'. I believe that if you regularly service the bike then it will be fine. Noel is a good guy for this thing as is Ed and Chuck.

If it ain't broke...don't fix it.

More problems are brought about by doing "what some guy said". If the guy owns an MV, and has experience with high mileage failures, then perhaps his opinion is valid.

These bikes are robust and run very well.

Check the concerns against known specifications for stretch and wear, and, if it's running well, leave well-enough alone.

As Chuck said, these bikes have pretty robust engines. As long as you treat it well (sounds like you have) then preemptive parts replacement based on racing usage (what is in the MV maintenance recommendations) is a little bit too cautious.

The open cam chain is just fine if you have the proper tools to brad the master link and know how to use them. Other than the chain, there is little in the engine I would be worried about needing replacement for well over 100K miles.

I know more than a few people who have put way over 100K miles on bikes with nothing more than routine maintenance. One friend had over 400K miles on his DL1000 when he retired it with a weepy rear cylinder base gasket. The engine had never been apart, and he didn't want to take it apart. He still owns it a and rides it occasionally.
How many miles on your car???

A quick and accurate way to check cam chain wear is to remove the tensioner and see how far it has extended. This means pulling the valve cover, tying the chain to the cam sprockets to prevent slipping, removing the center bolt of the tensioner to release spring pressure, and then carefully extracting the tensioner to see how far the plunger has advanced. Of course, you will need a point of reference (a lower mileage well maintained bike's tensioner to compare).

Another method is to simply remove the valve cover and note how far the timing marks vary from the correct position at TDC #1. As the chain wears the timing marks will get farther away from the proper alignment.

As others have said and I will concur....don't fix what ain't broke. But if you find the chain stretched then by all means put in a new one....the open kind. Any old skilled tech from the 70's should have the tools and knowledge to do that.


Oh...and I'm old fart and proud of it!!

I used to be fast....now I just dream about it.

Thanks guys! Put my mind to ease. These days though you cannot even say what "old" is for a human. But I've certainly heard some guys repeat over again that after 20k miles Brutales are basically just a heap of scrap. I thought I was just lucky.

esq'z me, "MV maintenance recommendations" - is that in the service manual or is it a separate document? You say those recommendations are based on racing usage, any specific numbers or guidelines from MV about what is considered "racing usage" by them?

@Buck: Following the Maintenance Intervals and schedule in the Workshop or USer Manuals is pretty conservative.

Something to ponder: These motors are inline fours (for the most part) and similar have been used in cars for ages... some with hundreds of thousands of mile accumulated.

This is an interesting thread. I have a '95 Kawasaki GPz500S as a daily hack, which I've owned since 2005 and 35k miles. I was the third owner, the previous owner is a friend and he looked after the bike. I didn't clean it much, but I serviced it every 3-5k miles max. It covered 84k miles and then it died.
It has never burnt oil, the exhaust gases were clean. The bike was only ridden by me.
Suspected cause is piston ring failure as the compression is half of minimum on one cylinder and minimum on the other, so it will not fire up.
I found this strange as the bike had been serviced regularly then? I did not expect this to happen. I never tracked that bike, but did occasionally red lined it and I never felt that is is getting low on power.

I am not questioning what could the causes of my bike's failure, but want to point out that even properly serviced bikes could fail.

So what I would say is if you think that your bike is getting on a bit, it probably is a good time to do a compression and a leak down test on your engine. This will uncover any non visible problems.

The difference could be that the RPM range of the bike puts it into an order of resonance that we don't see with car engines. I'm just spit balling obviously, but those second or third order resonant frequencies are probably what breaks this stuff and also what makes them sound so good.
