Bedding in my MED monster
#1

Fitted my new 1380 and am now trying to bed it in.
I was wondering if there is any better ways of bedding it in? I spoke to Steve at MED and he said run it on running in oil for 250 miles, drain and change filter, fill up with running in oil again for another 250 miles. Then change the oil again to the proper one with a new filter and get it set up on a RR.
Someone told me its better to do big runs to get the miles on quicker i.e Arun up and down the M4. The plan is to use it as my daily commute which is about 70 miles a day on A and B roads sitting at about 50mph.
Is it safe to go over 50mph and 3000RPM and better to vary the speeds? Why do you need to run an engine in anyway? It it the gears? The head and its components?
The main worry i have is that im changing gear all the time the cam is coming on and i worried that it may dammage or not bed in the engine properly.
So as you can see, im really paranoid and know nothing about engines so any advice will be greatly appreciated!!
Thanks everyone
Johnny

find the cheapest oil you can to run it in, and then change at 50 miles, and again after a couple of hundred. keep using cheapo stuff until it has run in.
whatever you do, dont drive like a granny all the time otherwise you will glase the bores.

I dont think the distance after the first 250 realy matters, but when you sell something with a warranty, you have to be sure the people buying the product are going to ensure that it is run in.

Bit worried about "whatever you do, dont drive like a granny all the time otherwise you will glase the bores".
Im brought two 5l tubs of Millers running in oil and a 5l tub of Millers CTV 20-50 oil. I also had it test run by MED to check all was well.
So, its best to run the car in at varying speeds. My route to work is a fastish A road (40-70mph cruise).
So will it be ok to run at the top end of that speed or is that a little to high?

You have the traditional, run it in slow, dont over load the engine etc etc for about 500/1k miles...
Or
the run the engine upto 4k rpm, drive for an hour, job done...
Like MS, my engine went into the car on the friday night before the showdown in 2005, 40 miles in it was doing 7krpm down the 1/4 mile.... and it's still running ok 18 months later

i used to work for a main honda dealer and on test rides all the new bikes were used to lets say their full potential * (with only 4 miles on them...) never had any problems i think the key is one early oil change and then just dont go too mad untill you get some decent oil in it...

Just drive it normally, and use the gears. The engine needs some load to bed the rings in.
I was speaking to someone at L2B who had a freshly built 1380. He drove as carefully as he could for 1000 miles, being really ginger with it. He ended up glazing the bores, and the whole lot had to be stripped down again so the block could be honed.

Aye I know, my Mini will only be used on nice weekends...Fair enough but when you only do 2000 mile in one year thats half a year gone with no fun.
I am tempted to do what I said, but when I hit the 250-300mile mark, open it up, and have fun, but change the oil when I said...

I plan to drive gently and normal throughout all the gears and rev range for 500miles. then after that i'll see what it can really do.
ive got 5 oil filters to do the oil when i feel the need.
