Dirty ugly 4RT rebuild.

[ahell]

 

I bought this Montesa 4rt in June. I've been meaning to post the work for a while.

A touring motorcycle...
It's rotten, completely neglected... but I got it for an indecent price. (and I have quite a few parts)
There it is, disgusting at its purchase.

 

First step washing the machine ...

Iin the trash:
The swingarm, the chain kit, the tires, the trim, the air box, screws, pads, rear disc, etc.

I repaired the chassis, the bearings, sandblasted the triple clamps, fitted a tech aluminum fork, new braktec master cylinders, new latest generation braktec caliper and new hose. 

The orange wheels were in good condition but I didn't want to restore it in Repsol.
By stripping the orange paint, I discovered a superb gold. (Standard 4rt has gold wheels)

 

 

I still have some paint and primer left to remove from the wheels before replacing the tires.

I repainted the ignition cover, did the service... and then there was tragedy.

 

Very low oil level on the engine side, lack of lubrication, timing chain shoes which are melting and sticking in the suction strainer.
Basically, I have to open the engine.
I don't know what I'll find, even if it doesn't click.
But I'm going for the skates, the timing chain, the bearings at a minimum (there is some play).
While knowing that there are great misfortunes that the piston, the connecting rod, the cylinder... in short we will see.

 

 

 

I'm going to take inspiration from a full black motorcycle that Mitani had prepared. I might reassemble an original Showa in tees repainted black. As for the wheels, we'll see. I still have a set of 315R wheels that I can repaint black...or just keep the gold ones. I received a Rikizoh adhesive kit from Japan black RTL, black mudguards and had purchased a flat tank for a while.

I gotta say that I love your posts and seeing “rotten” turned to “gold”. Can’t wait to see the end of this show! Thank you!
