YZF750R misfire at 4000rpm - help!

well, you haven't owned very many bikes, have you...

 

true...

 

Any musings on why it hasn't yet become the norm when you'd be hard
pushed to find a car without it?

 

Bike buyers tend to be a conservative bunch and prefer the supposed
reliability of carbs.

FI on bikes suffered from unreliability in the early days, leading to
the above pov.

FI on bikes isn't really all that well sorted yet. Fine most of the
time, for most bikes, but isn't 100%.

Fwiw, I'd be keen on FI, as long as it was user serviceable.

I don't think bike buyers are conservative. If they were they
conservative then Kawasaki wouldn't be releasing bikes like the ZX10R.

That's true.

Disagree. Both have my FI bikes have run just as well as my carbed
ones. The CPU in the GSXR is more powerful than the desktop PC I
bought in 1996.

I think the days of user-serviceability on all areas of bikes are
numbered. Especially electronic bits.

 

Cats on cars I assume you mean? Why do they make a difference?

 

Previously on ukrm, Ben said...

I've never had a fuel injection problem on any of my bikes.
I've never owned a fuel injection bike though.

 

Well, cats are pretty much required on cars to pass emissions tests, not on
bikes.

AIUI although it is possible (and has been done) to make a carburated fuel
system work sufficiently accurately to work with a cat, it's a damn site
harde than using an FI system.

Nothing much if everything remains working as it should, but given the
problems with air mass sensors and various other gubbins on car FI, I'd
like bike FI to be user diagnoseable and repairable without it costing
an arm and leg for necessary bits.

I don't see it happening though. As time passes, systems like that
become deliberately more complex and the manufacturers' unholy alliance
with their respective dealers will make sure that diagnostic tools and
spares will be unaffordable for the average Joe with just one FI bike.

Well...

The alternator stopped charging my car. Had a look at it and it became
apparent that it was the brushes that were shot. Called a motorfactors
and they said they didn't sell the brushes. I assumed this meant I'd
have to buy a combined brush/regulator set. No. All I could get was a
recon alternator.

When I started fucking around with engines you could get brushes for
anything.

I ended up getting a set of brushes for a washing machine or similar and
grinding them down with a dremel. They are reducing the number of
user-servicable parts by design. Still vehicles are *so* much more
reliable than they were.

Who could release a bike with a bespoke holder for a spare set of plugs
for when the ones in the bike oiled up these days?

Ducati?

 

Yeah, good point.

It's all Taylorism isn't it.

 

That wouldn't be a bad idea.

FW Taylor; management theory stuff. He did some work for Ford in the
early days where they set up production lines.

His thing was all about seperating men into craftsmen and drones.
Basically he tried to deskill every task as far as possible so that it
could be carried out by someone with minimal skills; and also a low
wage.

Course this is all based on memory of stuff done 20 years ago so it
could well be wrong...

 

This is also the principle McDonalds (et al) work to. Hence there was no
longer a need for capable chefs who could make or break a diner.

What I can't remember, is who came first? As an extension to the
original production line principle. The deskilling of the car industry
or the fast food diners?

 

Ah yes; I remember reading that sort of stuff years ago. Ruthless
bastard who treated people as commodities and machines.
Old Henry probably loved him.

Your argument is somewhat undermined by the fact that the bikes you've
just listed appeared in the late 90s, some 15 years after BMW and
Kawasaki went mainstream with FI

 

Honda: GL1200SEi - 1987; RC45 - 1994
Yamaha: GTS1000 - 1993

Triumph? 2000?
