triumph t 140 fuel type

I am considering getting a Triumph T140 E, 1980 can anyone tell me if it
will run on unleaded petrol. Also what should I need to look for when
purchasing, IE smoke noise ETC.

 

Not really, no. Use an additive.

Gawd. Just about everything. Not a Trumf expert, me, but SWK will be
along in a moment.

 

Triumph switched to hardened valve seats in production year 1972 - 73
so AFAIK all 750 should be ok on unleaded. IIRC The valve guides are
likely to wear so they maybe more susceptible to non leaded fuel[1]

They will tend to smoke a bit when on the side stand, top end noise
isn't generally a problem these are after all pushrod engines. IMO a
loose tappet is better than a tight one. Check that with the engine
running that oil is returning to the tank (OIF model so under the
seat). Check for play in the primary chain, all bolts are present and
correct (rocker cover bolts tend to go missing). There's a bit in the
UKRM FAQ on buying SH bikes have a look at that.

One problem is that because the Triumph twin engine is so simple every
bugger thinks they can strip and rebuild one so there will be a lot of
horrors out there. If you really don't know what to check for I'd
suggest you either walk away or take along someone with a clue

They did? Blimey. OK, I stand corrected. I never knew that.

<swoon>

My idol has feet of lead.

 

It's a brit, innit. Ask him something about some crap Jap twin from
1979.

 

Probably didn't last long enough to exhibit problems with unleaded...

to ejaculate:

My idol appears to be wearing wellingtons. That appears to be rather
useful as he is standing in a glutinous puddle.

 

Thus spake Timo @ work unto the assembled multitudes:

That's right. The valve seats probably stayed in pristine condition while
the rest of the sorry heap fell to bits around them. It certainly happened
to me (1973 Tiger 650) and I swore I'd never buy another Triumph. Ahem...

I think there was a crap batch of valve guides. Both my Bonnies wore
their valve guides out in under 10k miles. One was a blockade Bonnie,
the other was an innediately post-blockade Bonnie. Should be OK after
P reg.

 

Thus spake Mike Fleming unto the assembled multitudes:

I can't remember how many miles my 1973 Tiger 650 had done, but it was an
exhaust valve guide failing spectacularly which hastened its departure from
my ownership.
