Hi
My 15,000 mile (standard V100) service is due soon .qurious as to how many V100 owners are already pass the 15,000 mark in general, and in particular about the service:
What was the total labour cost?(In Hr terms)
Were the valve clearances within spec, or
an adjustment was required?
Was the alternator belt replaced as per
the recommendation? If so how did you
or your mechanic determined the tension
frequency(180Hz is the spec), dd he use a digital frequency meter, or just thumb gauged it? The belt on my bike seemed pretty loose from dayy 1 and has a reasonant frequency at 2200 rpm where it squeeks.
No replies to this post I see?? Trying again instead of new post.
How many Mandello owners at 15k service needed new valve shims? If so, how many out of spec? Also curious re feelings about alternator belt replacement? Just how dangerous, if at all, of not replacing? Any input appreciated. Ta!
I had my V100 Mandello serviced by Jim Allan in June 2025 at just shy of 2 years old - they changed spark plugs, oil + filter, air filter and the alternator belt, they also had to adjust at least one of the valve clearances.
In response to the OP, I have no idea how they tension the belt - having done Ducati timing belts myself for years by hand, it can’t or shouldn’t be that complex to tension an alternator belt.
I was curious so asked them to let me have the old belt. The mechanic and I had a chuckle as the belt removed looked identical to the one fitted i.e. the one taken off showed no signs of wear at all after 2 years.
In terms of cost, it doesn’t appear to show an hourly rate on my invoice, rather a fixed price for the service labour which at that time was £268. Big line items on the parts cost were oil, air filter and plugs which by the time you add VAT was £247.
The major service on my Stelvio was slightly more costly than @Bonny64‘s and no shims needed adjusting. Getting an estimate for how ‘dangerous’ not changing the alternator belt at that major service would not be realistically possible in an owners club - I doubt if even MG could estimate such a thing. How many people ignore that operation having spent 8-10k on their bike? What proportion of owners have even reached 15k miles yet? Probably both numbers are small.
Thanks to you both Bonny and Barney for your input. I am well aware there are no definitive answers to all the questions around recommended service items. I am a person who has always done my own servicing on all my vehicles. That whether under warranty or not. Most often the biggest part of the bill is labour and time. My time is free to me and parts pricing often varies a lot and can save there also.
I have never had a machine of mine die on me and I am strict on keeping up with fluids/filters and wear replaceables. Simply a tad suspicious of one size fits all junking of perfectly serviceable items which too often are a CYA response from manufacturers. Just another one of these percentage bets or attitude to risk for me.
My Mandello is still new to me and barely at 5000 miles. I will keep following owners experiences on here and elsewhere with interest and base my decisions on balanced thinking rather than fear. Ta guys!
