Today at Atelier Kaz - ex-Honda R&D, F1, Indy/CART engineer

The coolant pipes.

Now looking so much better but I must stop here as I don't want making the pipe wall too thin.
The bleeder plug was very rusty as well.

Will apply silicone grease to shut out the oxygen and moisture.
















Yes, it's dirty…..
The TH body.

Someone already touched the idle air adjust screw but looking at it from the back side, I think I must replace it….

Will thoroughly wash it.

















The fast idle valve and the EACV.

The meshed filter (yellow arrow) was covered in full of black dust.

Will be cleaned and filter/o-ring to be replaced.
