Hello Tim
A bit, as most Laverdas in Finland are either Breganzie twin or triple, or 125cc LB125+some of their successor models.
If it has the 11mm front master, according to conversation I had with Ducati Paddy some years ago the rebuilt kit has not been available for years.
Ducati Paddy suggested it could be bored to 12mm. Some else master may be also suitable.
Not sure about the caliper rebuild kit. The caliber should have a stamped code somewhere that identifies it, a couple of small stamped numbers and digits.
I have found mostly Italy is the best source for LB125 parts, some other old stocks have been in Europe. Those old stocks use to have mostly those parts left no-one needs. Have heard a rumour 3C Moto in Italy is able to supply some parts better.
I think Kelly Moto in US may still have something available.
The biggest issue in LB125 series use to be the design flawed cylinder, the usual repair was to simply replace cylinder and piston that didn't solved the issue. The rest of the bike is almost bullet proof.
There are a couple of variants available from the piston and cylinder, at least LZ125 pistons, early LB125 piston with one piston ring like the Zündapp piston, then there is a later piston with two rings. The piston has some availability, at least Scafuto piston in Italy still had some availability some time ago.
In Finland people used to bin the badly damaged cylinders. Currently the availability for cylinders in any condition is around zero.
Nowadays there are businesses that could repair and resurface even the badly damaged cylinders.
With Best Regards,
