What fuel does a Suzuki GP100 take?

Just bought and am doing up a Suzuki GP100 to learn on. Unfortunately
I'm pretty ignorant of bikes and have no idea what kind of fuel it
takes(!)

Is it LRP or unleaded? I've got the 2-stroke mix figured out, just
can't find anything in the Haynes manual or on the net - I guess it's
too obvious ;-)

Cheers in advance.

 

Unleaded.

Almost every Jap bike since year dot runs on unleaded.

 

where dot ~= 1971-73, depending on model.

 

I was going to say "70s", but that seemed too accurate
when I was trying to be vague...

 

And being specific my GP100 ran on unleaded for years (as per manual).
Got me to/from work for 3 years of that, got me through my test, and
I finally saved up enough for a..... gpz305. Please don't laugh - I
didn't know......

it was THE worst bike I've ever owned. They were crap, and mine was
the worst of the lot. No fond memories of it at all - OK the first 3
months were good.

Also, they don't run on 2-stroke mix. That is only for BSA Bantams, most
mopeds, and Eastern European junk. Instead, you have to keep the oil tank
topped up with 2-stroke oil. A pump delivers the right amount of oil
directly to the intake port. If the oil tank ever runs out of 2-stroke
oil, then the engine blows up.

If you add 2-stroke oil to the petrol as well as putting it into the oil
tank, then it will upset the carburation, actually making it run lean (by
reducing the proportion of petrol), which could burn a hole in the piston.

If you have been putting oil in the petrol and not in the oil tank, then
you will almost certainly have to bleed the air out of the oil line before
you can get things back to normal. If you don't do that, you may blow the
engine up.

Whilst we are on the subject, you should put ordinary 4-stroke engine oil
in the gearbox. Don't use 'gear oil', which is much too thick.

You could figure out all the above by reading the original user's manual,
if you have one. The Haynes manual will have all the info in there, but is
for people who know what they are doing (no offence!).
