Brisbane -> Adelaide, Top gear flat out...

1300 miles?!?! Dude.... you are goning to be one tired mofo. I did a trip last summer on my 1000 and I did 1500 miles in 2 days and I was tired. But, then again, I'm probably a little older than you are...

 

This is aside from the boys in blue who would be very keen to see you locked up. A bike with a real 22,000km's on the clock will easily take 2100km's of continuous riding - however a servivce is advisable before and after such a hard slog. If you sat on 160-180km/h the entire way you'd be eating petrol at an alarming rate... most likely with a tank range of about 100-120km's (assumed average range of 160km/h).

The truth is the described scenario sounds very much like the stress you'd put a bike under whilst on the track. Most people realise that pushing a bike too hard for too long will result in a failiure of some sort. It just depends what the existing condition of the bike is in, and any weaknesses present. I'd be thinking you'll crown the tyre's, end up with a very dirty air filter, and general accelerated wear and tear.

 

Am I correct in assuming that crowning the tires is to wear a flat spot in the middle? It's a new term to me...

 

That's what I was guessing...

 

Crowning is indeed to wear a flat spot in the middle of the tyre, generally from excessive commuting or freeway runs (or burnouts).

I've kept a few 250's above 13,000rpm for extended periods whilst chasing bigger bikes, but never at a constant rpm for very long. It was usually through the twisties or sweepers and as such had it between 13.000-18,000 for almost 2 hours. If anything, it certainly kept the spark plugs clean and blew out a few cobwebs... but anything more than a few hours i wouldn't be so sure the bike would like.

As i said before, the best it'll do is simply accelerate the wear and tear on all moving items on the bike. The worst it will do is cause a failiure of a part.

 

I went to the grampians a while ago to do some rock climbing and took my bike, held speeds of around 120-130km/h and got better milage than I have when running around town (17-18km/L compared to 13-15km/L)

I sat in 6th at around 12k-13k rpm down all the freeways/highways.

 

That would be because of the wear pattern on your needles has caused it to run rich at about 100km/h. As you were riding at a non standard speed with a non standard throttle amount you would've been perfectly in tune.
The other thing is that there is a point at which efficiency goes out the window on a 250. If you plot it up you'll find the bikes are most efficient at about 55km/h but honestly who wants to ride at that speed. When they get to about 140km/h they start guzzling more, and when they hit 150km/h (or whenever you need to pin the throttle open) then they'll eat more fuel still.

I'm sure if everyone who was having fuelling issues replaced their tubes and needles they'd be very very happily surprised at how a properly tuned bike is meant to react to throttle input.

 

Emulsion tube is the bit that the needle slides through.
Where there's movement... there's wear & tear.

 

ive done a few hour long holds on the fizzer. at around the 110 mark. it all depend on the condition though, coz every time its different. I do find though that after running it constant for so long that it runs a bit ****, so now and then, i drop back down a cog of two and give it a squirt to redline and them back down again.

I think you would be better off making a trip out of it and stop over a couple of nights in diferent places. and try and hit some nicer roads. 4 - 5 nights you should be able to do the coast with out too much problem. And if ya fizzer is in good tune it will do those kinda miles easily. Consider an oil change before during and after the trip if your concernd.
