Piston Clearances

[Jimi]

Good Day everyone,

I have a Tomos Sprint moped that I'm working on.
(50cc, air cooled engine.)

Can't find the piston-to-cylinder clearance anywhere.

Can anyone give me a rough idea as to what the
piston clearance would be for a small air cooled engine
like this?

Thank you All,

Jimi

As a footnote, I believe the cylinder is steel lined, or cast, because
there are oversize rings/piston available.

.........so, I don't think that it is a plated cylinder.

Thanks everyone,

Jimi

Try this site:

Moped

It has service manuals for your moped. How is that thing in the whoops?

.........I 'did' buy a parts & service manual CD rom,
but it does not contain any info on the piston clearances.

Tomos, Slovenia, is not good at up-grading their information.

Any info on piston clearances for small 50cc air cooled engines
that you guys have would be a help.

Thanks all,

Jimi
