Carb Clean

I invested recently in an ultrasonic cleaner and proper solution to clean the grubby carbs.
I had previously purchased new parts from Yambits to complete the rebuild, New jets,
needles, choke, seals and screws.

So after a good going over with a dremil and stainless steel brush I removed the old paint
and oxidisation and then gave them a good cleaning in the UC.

Next up I need to make a list of what parts I need to complete the job and what tasks I need
to do on the bike to finish.

Pistons

I managed to source 2 identical branded pistons
as a kit, with rings, Clips and Gudgeon Pins.

I couldnt find any info regarding the "Made in Taiwan"
Speed brand.

The tolerances work out pretty good and are as follows:
Cylinder oversize measurement: 0.035 - 0.040 = 0.035
Piston Ring end gap: 0.25 - 0.40 = 0.30
These are approximate measurements with feeler gauges.

Shafted

Another engine component rebuild, the crank was in a terrible
state as can be seen from the pics. I managed to get this shipped
to the U.K rebuilt and sent back to me cheaper than I could buy
the parts and have it done here in Ireland.

So the crank was cleaned and fitted with new main bearings x 4,
Labyrinth Seal, big and small end bearings and new con rods
and then balanced.

Bling

So its been a while and the project has been limping along.
I have been concentrating on 2 big spends: Crank re-build
and sorting out the engine casings, heads and barrels.
The images below show the parts Vapour Blasted by
http://www.vapourblast.ie/. All parts were stripped to the
original metal finish.

Electrics

Started into the fitting of the electrics.
Front end is now complete and the loom
is loosely fitted.

I need to fit the plastic under trays to the
rear frame to determine where the regulator
rectifier etc are to be placed.

I was going to use the rear standard
mud guard, but its getting the chop and will
use an alternative.

Gear Change

Using some more aprilia RS125 parts I was able
to set up the gear change linkage.

Caliper finished

In preparation for the final dry build I
managed to get the front caliper finished.
coated with heat resistant primer covered
with heat and fluid resistant paint.

Im also modifying the bench for the slightly
longer wheelbase and Bram was lending a paw
to the carpentry!
