running in a new bike
 

never owned a new bike before

Manual states max revs 5k for 500 miles , what approx speed does this relate to in top gear?
Also will it do much harm if I did 100 miles at a constant 5k ? or is it better to vary the speeds ?

cheers

From memory 5k = 70ish! (I think)

Best to vary revs rather than keep constant.

Go up and down the gears and vary the revs as much as possible...

various schools of thought on it, some say thrash it some say stick to it... :roll:

It says in the manual to vary it.
There are many schools of thought on this, as Ian says, but the manual seems to be a good compromise. It doesn't suggest you baby it, by any means, but also doesn't say to thrash it.

The engine at 5000rpm is 70mph

The main issue is the gearbox...plenty of cog swapping.
Needs running in to.


The engine is free revving so keeping at 5000 is very difficult...just go gently and that should do.

The thrash or gentle approach depends on whether u want to keep it or not. :D

I'm reasonably certain the main issue is bedding in the piston rings to the bore.

A controversial word of advice....

The slower you ride it the slower it will be after the running in period.

.

That is true...
But also the gearbox too. The gearbox was very stiff on my new bike.

The running in period has been the same since Adam was a lad. Whether you really really need to follow a set procedure is open to question. Doesn't take in better materials or finer engineering quality. But since a motorcycle is a large slice of cash then it's up to the individual owners to decide.

I suppose.

Here's a post by somebody who should know a fair bit about engines http://forums.sv650.org/viewtopic.ph...running#365390

Never over strain and never over rev...simple advice for running in. Up and down the gearbox as much as possible also will see her eased in a treat. After a couple of hundred miles dont be afraid to go an extra 1'000rpm or two over the specified limits....on say a few short sharp brief acceleration runs. 8)
