Running-in new bikes

[jafa18]

Not shure if you have read this, but i found it to be very interesting.....
this guy seems to know what hes doing, after over 300 run in's using his method, and the piston comprasions at the bottom of the page are a bit of a wakeup.....

I have spent many years karting ie 125 on methanol, cadet and 125 engines. Doing many many rebuilds. Although we didn't now it at the time, due to impatience during run in (the first few times) we where using the mototune method. So we kept doing it. Our engines always went really well!! I discovered their method a couple of years ago and it confirmed what we where doing for the last 20 years.
Although I would qualify this by saying if your going to keep it for 10 years, and never going to expect it, to give the most it can deliver, use the factory method.
But if you want it to go like the clappers and still be a good reliable bike. Ride it and ride it well. That doesn't mean of coarse thrashing to death. Read the moto tune thing, changing the oil is inportant as well

My opinion only!

your bike is already run in. once of the production line, it has gone straight to the rollers where they take it up through the gears hitting the rev limiter to make sure all is well!!
ride normally.
when running my car in I hit the rev limiter 6 times in the first drive to make sure those rings seal gooood haha

Yuppp , i see you have read all the bullshit garbage myths from days gone by and believed them all. As i have to deal with owners killing $ 50,000 cars all the time i just love to hear that kind of crap. not (if the manufacturer has to spend all his money on warranty rebuilds then the cost of a car / bike will creep up, thats economics.)
A small peice of trivia told to me by a senior staff member of Blue Wing Honda, in 1976 the CB650 was launched here for (memory) about $1600.00 NZ and it cost Honda America $150.00 per unit to make.

As its already well and truely covered above , give it plenty of varied revs and work a few hills without putting the engine under load at all . A consistant rev range will creat an oil burner after a while.

In a previous life I was Product Manager for Honda (Cars) NZ. I used to pick up a new car from the plant and drive it to Auckland and back ... run-in all done. I had the fastest cars in the fleet consistently and here's why.

To bed in the rings, they need pressure exerted on them to de-glaze the bore and seat the rings. They also need to heat up and stay hot for a while. We used to run the cars not too harshly all the way to Waiouru and then it was flat nackers (redlining thru the gears) all the way to Auckland and back. (Best time Porirua lights to East Tamaki turnoff = 5hr 57min)

As already said ... don't labour it, don't fang it for the first 500ks but don't nana it either (that's the worst thing you can do). Make sure its above the max torque rpm and then use the throttle and get some pressures into the cylinders.

Our dealers used to get brand new Civics and Accords in for their 6,000km service that wouldn't pull the skin of that rice pudding. They all belonged to nanas who ran them in like they used to do with their 1952 Morris Oxford.

Those vehicles were usually given to the apprentice to thrash the ring off them up and down the motorway for half an hour - you should have heard the praise they got for doing a "marvelous tune-up on the car!"

Give it heaps, Thats what I always do on my rebuilds (have done four now) and they seem to go sweet as, I reckon don't nana it otherwise the rings won't bed in, but thats my opinion.
