But that's how I normally ride?

He's right you know.

I Rode it as the manafacturer stated for a while, but had the frequent silly period of insanse revving a redlining each gear.

What he said.....

Actually- I followed the manufacturers advice and used a strip of red tape on the tacho as a temporary redline, which I moved as the miles went up. However, if you read the article, the arguement is VERY convincing- particularly when you take the comments on oil into consideration.

Cheers,

This topic comes up regularly but people come and go on the forum so there's always scope for repeating it.

Go to "search" and type in "break-in" in search-words and "embee" in author for a few examples of previous discussions.

The engine industry still uses the concept of a break-in period, even if it isn't specified as such. It comes from fundamental aspects of manufacturing components and reaching ideal running conditions. It doesn't happen all in the first hour, and if you are looking to make and engine which will last 100k miles with good oil consumption, you can't expect it to fully break-in in a few miles.

Funnily enough today I was going through some work I did a few years ago with a European car manufacturer who was experiencing some piston scuffing failures, and there were extracts from an article by a major piston manufacturer describing the reduction in ring and groove temperatures throughout the break-in period, typically 15deg C (mean values) lower at a given running condition after a full break-in than at the start. Peak instantaneous temps will vary more than that. That can mean the difference between the oil film holding up and not.

It's a bit like baking a cake, 30mins at gas mark3 will work, 10mins at gas mark7 won't.

One thing to bear in mind is that running in is not just about the rings and bores.It may be that they benefit from a good thrashing in the first twenty miles,but I bet the big ends and main bearings are less keen when tight.Engines on SVs that break prematurely often seem to involve some sort of crankshaft failure so maybe running in traditional style is the best plan.
FWIW I have run in two IL4s and followed more or less the official way,but never been too worried about giving it a couple of thousand extra on the revs.The main thing is to not let it labour at low revs and keep stoking the gearbox.Both those bikes were Kwak sportsbikes and neither ever used a drop of oil.

If the engine lasts that long, how much do you reckon a 120,000 mile service costs?

my 120k service cost in the neighborhood of $275US(£150)

coming up on my 135k service in a couple weeks

oh, ya, forgot to mention, I ran it in pretty much by the book

Buy a used bike

Most of us won't run the engine to a fifth of its natural lifespan anyway, so reducing the lifespan a bit, frankly, who cares? Running it in badly is almost certainly worse than running it in wrong though- I've heard too many people say "I had to keep it below 6000rpm for 500 miles, so I stuck to the motorway in top gear to get it over with" Aaargh!

Mine was a demo bike, which at the shop in question means one of the staff ran it themselves for the initial period, then the savages were let loose on it. It's quite healthy

Hmmm... I just found a gap in the market.. I think I'll open a bike shop that does a running-in service for a fee...

I like your thinking, need any help...
