So that's the engine bay complete, just ready for the newly refurbed round tops to go back in and a freshly painted airbox.

Just a thought get the battery charger ready to go once back together.
How bad would it be to get rebuilt then need to wait until the next day as battery charges up.

Here's a breakdown of the work done for anyone interested.

Hitachi ISO x2

1- Carburetters fully stripped to component parts including complete disassembly of all linkages.
2 - Degreased before being ultrasonically cleaned and assessed.
3 - carburetters then sandblasted using my own formula grit which externally light and gives an Original Finnish.
4 - carburetters then again examined and assessed before a final ultrasonic clean in fresh fluid.
5 - carburetters sent to the engineer to have throttles upgraded with custom throttle roller bearings.
6 - All metal parts Zinc gold plated.
7 - carburetters assembled using new parts.
8 - new parts including - new throttle spindles with custom roller bearings, new main jets, new metering needles (SM), needles valves, float chamber rubbers, seals and gaskets as required, all missing/damaged parts replaced or repaired.
9 - tested for leaks and correct function.

Inlet manifold -

Inlet manifold was found to have several missing damaged parts and water chambers restricted with corrosion.

1 - stripped and assessed.
2 - degreased and cleaned.
3 - time taken to remove and clean corrosion before vapour blasting.
4 - All metal parts Zinc gold plated.
5 - damaged water pipe extracted.
6 - Assembled using new parts, and replacing USA spec cross chamber with U.K. spec cross chamber (supplied by yourself).
7 - New parts include, main water pipe, special sealing nuts and o rings, new water flow pipes manufactured/replaced (only one was available so second one was manufactured).
8 - heat shield cleaned and painted with heat resistant paint.

Carburetters installed onto inlet manifold and set to Datum/Factory settings.

Here's a link to the drilling out for roller bearings:

Great stuff. For the benefit of others can you say the cost? Might be an alternative to sending them to the US to ZTherapy (as I did). I posted my invoice from ZT somewhere on the site ...

Hi Mike - I paid £850. Roller bearings are an upgrade. Duration 3 months. Alan suggests a range of £700 - £850 depending on what you are having done. I had no shipping as it was local.

Hope that helps anyone who might be considering doing the same. Alan (Scotcarb) is based in Bathgate, just outside Edinburgh. His contact details are in the pics.
