Chain vs. Belt Drive

fair bit of different to stresses placed on a timing belt to tthat placed on
a drive belt ????

 

Engine revs are irrelevant when you're talking about rear wheel revs. I
don't remember what the gearing was now, but I changed to a smaller rear
(Fatboy) pulley when I changed to the second belt. Acceleration wasn't
affected. 130ks was usual touring speed.

Look up the gearing for a 1986 Softail (First belt) and a 1990 Softail
(Second belt and rear pulley)

Engine revs have nothing to do with the speed of the rear belt. That's
down to the gearing. I toured around the country a few times, drag raced
and commuted on that bike. It was my only transport for most of the
eight years I had it.

What width? Standard width. I don't know of anyone making rear belt
setups wider than stock.

I might also mention that the first belt had a large stone imbedded in
it for more than half it's life. That's what killed it eventually. It
started to delaminate at the edge near the stone and teeth started
peeling back. Even then it still lasted the three weeks it took to get
the new bits, losing 3 teeth by the time it was removed...

 

Here 'tis.

1986 Softail - Trans pulley 32 - Rear Pulley 70 - Final drive ratio 3.37
Number of teeth on belt - 132

1990 Softail - Trans pulley 32 - Rear Pulley 61 - Final drive ratio 2.94
Number of teeth on belt - 128

 

I'm surprised it's that cheap actually!
If Doug's 130,000km is typical then that the equivalent of about 3
chain-and-sprockets so it'd fairly neatly pay for itself. (Not counting the
lube costs)

 

Ermmm... I've yet to see a street cruiser (especially of the 800cc ilk)
doing that with a chain either, so I don't think I'd be missing out on much.

Many thanks to all who replied; I think you've managed to set my mind
pretty straight on the subject. Just a matter of waiting a couple of pay
days to scrap together the funds. In hindsight I should be glad I didn't
have enough $$$ on the credit card to order that Kettenmax chain maintenance
kit.

Now then comes the next question... How many cases of beer (and of which
variety) would I have to procure in order to assemble a motley mass of
newsgroup participants at my place to help me install the kit?

says who. a few years ago when I live in Sydney. as I was leaving Kingsx
once an FXR went past me.
cops watched him go past. so the cops decided to try to get him. a few of
his mates (he was a member
of a club) delayed the cops as best as they could. as I watched him go he
was trying to keep the front
wheel on the ground. he was laying as far forward as he could and the front
wheel came up in every
gear including top (5th).

I think the main reasion that chains are used is width my belt is 32 or 38
mm wide. the later models
are 25 mm wide. a chain is what 12 mm wide. that would make a big differance
on how they design
where it comes out of the engine and swingarms. chains help keep the bike a
little bit thiner,

A mate of mine who's a far better rider than me used to do mono his '80
Sturgis impressively well though it was hard on belts.

He also used to mono his GS1000G shaftie years before that. Wait, that
can't be right...

 

My V-Max used to mono (well... I thought it used to... then I learnt
better and realised shaft drive bikes can't mono so I've put it down to
beer and fatigue induced halucinations

Not surprised at that.. you drink shit beer!

Johno

Real beer mate?

 

Nah... you can keep your 'Carlton... made from real beer' I'll have a
Toohey's Old ;-)


G-S

 

He's a frickin' designer, he has NO engineering qualifications. Haven't
read the article but if he wrote anything about engineering he's making
it up

Pretty much a moot point these days, isn't it? Considering CUB owns
Tooheys (and has modified the recipe to their tastes)?

Bring on the Guinness, I say. But the real stuff from Ireland, not the
bottled immitation from Carlton.

Or if you can't handle a real stout, perhaps go for our locally produced
James Squire?

Worse, John. He's a freelance Pom bike journo (Kevin Ash, hence "Kash")
who started out writing for Fast Bikes under Colin Schiller...

 

On my bike, Harleys, and I suspect, most bikes, the gearbox output shaft is
turning _faster_ than the engine in top gear.

Got one!

Not a real mono. Happened to me once on my, would you believe, Guzzi 850T3.
Taking off uphill from a set of lights with Helen on the back in a spirited
fashion and the front wheel came off the ground. I thought I had done my
first mono, but later found there was a gravity deficiency on that
intersection with an anti-coriolos effect. Some months later we went to a
pub on that corner and, crossing the road on foot, I felt quite
light-headed.

Did you try walking backwards?...

 

I had enough difficulty walking forwards.

X-No-archive: yes

....People just laughed and said,"It's a publicity stunt"
I'm walking backwards for Chreeeestmasssss...
