getting a new bike .......??

Bang em off the limiter

I remember my last day working in as a mech in a bike dealership.
I took a Yam 350 powervalve out of the box PDI'd it and had 125mph on the clock down the bypass....
I have also had a couple of bikes that did not go as they should have. I bought them from caring proud owners who never thrashed them.....
 
I ran my first GS in as per the manual and it was still using oil at 24,000 miles.

My second, new last year, was given the treatment recommended on this website.

It stopped drinking oil at 6,000 miles and runs much better than the first one ever did.

You'll find other threads on this subject, essentially it's to do with not glazing the cylinder bores before the piston rings have really bedded in.
 
In my time as a bike mech - every bike we PDI'd we'd redline down the dual carriageway.
They were all jap bikes though.

Never had a problem or any comebacks.
( apart from getting caught wheelying an FJ1200 - but thats another story :) )

I think this is an excellent theory about running -in and most of the info is correct.

Running-in was for machine tools built before the war - not precision machined engines.

The oil change at 20 miles is particularly good advice.
 
It's certainly what I'm gonna do when I get my 12, not red lining mind.

I will probably change the oil at about 30-40 miles though.

The beemer's got a lot of ring to bed in in terms of piston circumference.
 
Read this Motoman ( could it be an alias....:nenau ) concept before & "to me" it's all smoke & mirrors ( and that's being nice..:D)
A few punctated truths to validate the BS.....
 
so lets see

2 authoratitive reports saying basically the same thing...

manufacturers revving engines to the redline on a rolling road straight off the production line to check them....

lots of stories about gently run-in bikes smoking cos the bores are glazed...

which bit is the smoke and mirrors ?
 
Apart from my own experience ( my GS uses very little oil by the way ) I do wonder why the manufacturers recommendations are a source of error....:nenau
Motoman ( who is he, what are his credentials ?) Other than having a sponsored website with a multitude of hits....
 
i suspect the manufacturers running in methods are as they are because the "hard" method leaves rather a lot of room for error on the part of the owner.


if indeed it is a good thing at all. which i doubt.
 
forget the motoman website if u like - i just found it to back up my own theories / experience

The http://www.pumaracing.co.uk/ holds a lot more sway with me - the guy certainly knows what he's on about - read the whole site.

no crappy merkin adverts - just pure well founded knowledge - u can't beat that :thumb
 
On a similar vein , at work we got two new transit vans with consecutive chassis nos, I ran one in , basically thrashing it from the start but keeping a close eye on the fluids and temp etc.
The second was run in by a colleague who drives like a total prat, never going over 50 mph, labouring it in gears and doesn't know how to raise the bonnet etc.
Mine was always 10 mph faster than the other one and accleration was better, it never used oil and had no engine problems.
The second one used oil and water and eventually dropped a valve and wrecked the motor.
Our s60 volvos are the same as were the K100's and the Pan Europeans.

Better, much better.... :clap :clap :thumb

I wouldn't static idle a catted boxer motor for 15 minutes at 2500rpm though, unless I had a fire extinguisher handy.... :nenau
