So seems our threads lost their way by getting trashed as usual by those that have nothing better to do except fleecing, and other threads that you are not allowed to speak about a certain sponsor, so back to facts and hopefully this thread will stay on track, otherwise it will be closed and another opened, so if you want a forum full of closed threads and supposed flounce threads, you are welcome to carry on.

Now back to the question that was asked and answered very technically by the few decent lads here that do take real interest in sharing technical info, have we found anything else yet, I personally was with my friend who is a top technical guy at BMW yesterday, and he is saying he is woorying about the life of the engines with these new emission standards.
 
I think that nothing dramatic will happen BMW will find solutions to Euro 5, the bikes will be fine.

Only time will tell Will, but given the amount of time most keep their bikes now, many will never notice, bikes with a 100.000 miles on the clock are a thing of the past.:beerjug:

100,000 mile bikes are not good for business; electric bikes are going to be a problem because they are mechanically simple; the manufacturers will need some new way to build in obsolescence.
 
Why are the new emission standards reducing engine life?
I'm out with a guy tomorrow who's LC (not a 1250 though!) has got nearly 110,000 miles on it so the basic engine will clearly do reasonable mileages. Just interested in what's in Euro5 that would cause problems?

Its fairly easy to explain that. The less fuel you introduce into an engine via the injectors the more the heat build up is. Fuel actually helps keep the engine cool. Thats why the partial LC was introduced in 2013 in an attempt to cut the emissions by leaning off the fuel/air mixture thereby reducing those emissions. So in order to keep the engine cooler, partial water cooling was introduced. The cooling of the engine now done using circulating water, instead of fuel, to keep it at a reasonable temp. With Euro 5 coming in the engines had to go full WC hence the 1250, all ready to be converted to euro 5 when the time comes. Im thinking (altough i dont know for sure) that trying to meet that standard is going to stress the engine by injecting less fuel and engines being so lean that damage can occur, because of the heat and lack of cooling fuel on the pistons. Thats it, as far as i understand it. But im sure someone will be along to trash my post, they usually do.:thumb:blast

The leaner you run an engine the hotter the combustion process tends to be. So the exhaust valve seats etc will get a harder time. To the rest of the engine in general it’s less of an issue. As I understand it euro 5 also targets a wider range of emissions compared to euro 4 and they have to ensure the engine will meet those targets for the expected life of the engine. Does that mean that engines will be specifically built not to last beyond xxxxx miles as beyond that they cannot meet euro 5 ??

Cats contain expensive metals as well so prices will only rise as manufacturers have to have more and bigger cats and other elaborate ways of reaching the new targets.

Given that manufacturers like Honda have said they will stop making combustion engines beyond 2030, I suspect they all know the writing is on the wall.

Exactly that, we will all soon be riding on some sort of magnetic elevated bike. :beerjug:
 
Interesting, i had my previous lc eu3 bike sent to HT.

I am convinced the bike ran cooler, the fan did not cut in half as much....

changed bike at 24k.

just been reading the Facebook treetop claims....

But you do know it is not allowed to use any of the words you have been using, I spent a day reading all that, and the Lambchop and Teapotone videos being taken offline, certainly tilted my boat even more, but again, you asked, and again thread will be moved, or my post deleted.

I didn’t realise that the 1250 is ‘full LC’, I thought that apart from the shift cam and extra capacity the cooling system was pretty much the same as the 1200??? Is there a diagram of the new cooling system anywhere?

Pretty sure the cooling system is unchanged on 1250
