Any question answered...

swapping some suspension forks (100mm travel - 440mm ish axle to crown) for rigid. would it make that much difference to the steering if i used 80mm corrected forks, eg. 415-420mm axel to crown? forgot to say, will mostly be using on the road if that matters.

thanks

dunno

all these buses that are going to sorry Im not in service, where is that exactly? must be damn busy

Measure your existing forks while you're sat on the bike; 440mm is already allowing for quite a bit of sag on a 100mm fork, if you tend to run with a lot of preload your 100mm fork could be closer to 470mm A-C. Taking 50mm off that is going to be noticeable.

In an internal combustion engine if you shortened the connecting rod length whilst increasing piston height (for a total of no net difference) would that increase displacement, or would it remain the same?

(I suspect the latter)

Displacement is bore² x stroke x π/4, so you have to change either the bore or the stroke (i.e. crankshaft throw) to change the displacement. Shortening the rods will change the side load on the piston and slightly alter the piston speed and acceleration curves, but it won't change the displacement. Raising the piston height to compensate for shorter rods is wrong - you should reduce the barrel height instead, otherwise the gudgeon pin is too far from the action and the piston will tend to rock more.

is there anything mdcc doesn't know about?

he dosent know where sorry not in service is

Loads of things - I'm rubbish on biology, literature, history to name just a few huge lacunae in my knowledge.

he dosent know where sorry not in service is

I think it must be near Barnet

Would I save a significant amount of money having an exhaust made of mild steel instead of stainless?

Or you can make it out of chocolate. Brown noise.

Really? Liquorice tyres also?

Displacement would be the same just the dynamic characteristics of the engine.

No.
Just bottom brackets giving the different chainline measurements. As not all BB are symmetrical.

Yes.

What in the name of arse are you talking about?

If you ever need any evidence of the stupidity of Americans, it's the Americanisation of the spelling of LASER. WTF is the Z supposed to stand for?

zimulated.

duh!

fuckin' noob..

Piston rock also depends on piston material and piston skirt design. The distance between gudgeon pin and piston top is reducing as materials improve.

Yes.

If you look on this webpage http://www.sheldonbrown.com/bbsize.html it mentions thee right hand (crankside chainline dimension) distance.

Am looking for that information.

Make sense?

I'm too fucked too look at what wwe were talking about. I thought you wantred the link to bb db?

No not really as material costs aren't that different.

I would go for internal mandrell bent pipes for the gas to flow without disruption.

Peasant. I'd just buy a faster car.

Plebian. I would just buy a proper sports car and drive around grinning smugly, knowing that no matter how fast you make it, it's still a Volvo.

Dammit shopping for a new car:

Amateur. I would just change π.

That π wouldn't last 10min in my house, i have emergency cream on standby.
