Superdetailing the Honda 250cc engine

ENGINE PLUMBING
I replaced many of the
plastic moulded bolts with
metal turned ones from
'Tuner Model Manufactory'.
The Tamiya kit tubing was
replaced with aftermarket
tubes and wires, all measured
and fitted accordingly. I
added wiring and connection
points for what I believe is a
sensor in the engine block, as
well as a few other additions
of bolts and connectors and
wires based on my reference
photos. The ‘gold’ coloured
parts of the engine were
actually a mix of Alclad 2
Pale Gold and Pale Burnt
Metal, which I mixed at a
50:50 ratio.
The rest of the engine
block was painted with
aluminium and a few shinier
parts were sprayed with
polished aluminium. I used

the Tamiya 'Detail-Up Parts

Series' Clutch and Front Fork

Set for the clutch. The clutch

itself was very straight-

forward to build without any

real problems and I added

some metal turned bolts on

the top of the clutch plate and

the for the attachment points

of the clutch basket.

For the carburettor I used

Bare Metal Foil cut into

strips to emulate the metal

clips around the rubber hoses

between each carb. Based

on many of the reference

photos I saw that the intake

trumpets were a whitish/

yellowish colour and most

likely made of some kind

of resin, so rather than use

the metal turned trumpets

supplied by Tamiya, I used

the standard plastic kit

parts and painted them the

corresponding colour.

The clutch was straightforward

to build; the author added

some turned-metal bolts on

the top of the clutch plate

Many reference show the intake

trumpets in a yellowish/white colour

and most likely made of some kind of

resin. The author used the kit parts

and painted them an off-white colour

Many of the plastic

moulded bolts were

replaced with metal

turned items from 'Tuner

Model Manufactory'

The exhausts were enhanced with the Hobby Design exhaust gaskets which look much better than the
standard parts
