| Unleaded or Four star [message #786923] |

Hi All
Wonder if anyone here can help, I'm picking up a 1982 Yamaha SR250 tomorrow
that hasn't been run since 1999.
So first job will be to flush the tank out and refill with fresh fuel, but
what fuel? I can't seem to find any information as to whether this bike will
be ok to run on unleaded or if I have to find 4 star or lead replacement
petrol.
Any advice would be greatfully received.
all the best, David

I believe that most 80s bikes, especially Japanese ones, are OK on unleaded,
with a few notable exceptions.
Of course I haven't a clue if the '82 SR250 is one of the exceptions, but
I'm sure SWK will be along shortly.. TOG?

Bog standard unleaded will be absolutely fine. They only ever needed
2-star, and AFAIR all jap bikes from much earlier than that were
designed so as to not require the lead additives.

1973 is the significant date. This was the year when the US mandated
unleaded fuel in all new motor vehicles, and pretty much every
Japanese bike made from that date will run on unleaded. The
exceptions are extremely few and far between, and tend to be exotica
like the CB1100R.

I don't think it was 1973 when unleaded was required to be used in all
new vehicles. As I remember it, it wasn't until the 1975 model year that
almost all new cars were _effectively_ required to use unleaded due to
their use of catalytic converters. In fact I don't think it was a legal
requirement that the cars not use leaded fuel, it was just difficult to
meet the pollution requirements without a cat, which of course precluded
use of leaded. One notable counterexample was the 1975 Honda Civic with
the CVCC engine which met the 1975 clean air act standards without using
a catalytic converter.
There were laws passed phasing out the concentration of lead in leaded
fuel, starting in 1973, eliminating all lead by Jan 1 1996 for on-road
vehicles.

I stand corrected. It was my understanding that it was US legislation
that meant post-73 jap bikes were designed to run on unleaded.

I had a 1990 (G reg) Cavalier which was on the cross over point. Mine could
run either unleaded or 4 star, but the following year, they went to unleaded
only.
Don't know if that *means* anything though.

That seems more like it.

And apparently it IS more like it:)
