Next time, paint job. This naked tank was a 2002 model.

Black fender mount and TRS Tech fork lightweight black axle.

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.

Mounting the Tech aluminum fork. Unlike the assembly with the 32 spokes wheels of the 4rt, Mounting a 315r wheel (36x spokes) requires an 11mm spacer on the caliper side wheel axle. The visual result is nice. The black tubes are darker than the Showa DLC treated steel tubes. The anodized Tech lowers reflect a bit of the factory Showa color. I like it a lot. The weight gain with the tech wheel axle is 750 grams. It's not a huge gain but it's still noticeable when driving in general. Having observed it, it helps to lighten a slightly clumsy front axle.

After months of stopping, reassembly resumes. Brakes and clutch hoses after a major cleaning to decontaminate them of deposits. Installation of the selector, the brake pedal, the gearbox exit protection. I need to rebuild a rear wheel spacer to slightly offset the caliper.

Latest modifications or parts: -Mitani texalium swingarm protectors - titanium fork 3xclamps screws, footrest plate and front frame tie rods. - Teflon handlebar end and titanium screws. - Michelin markings on the tires. - Mitani carbon air filter intake - Renthal handlebars and grips. The motorcycle runs very well. The chassis is well suspended for a 90kg rider, it brakes well. The motor is full and linear. The bike is efficient on natural climbs. It's a very nice bike and in its 2002 Lampkin livery, I find it great. I'm going to do a test with a tech aluminum fork to see how the bike behaves. I also have a longer Banyeres muffler (straight tube) to try.

Radiator fresh paint, electrical parts clean and exhaust My tip to tighten the flywheel with a piece of alloy. New oil filler cap

Factory mat finish. Titanium bolts will shine like a disco ball.

Very light sand blast on the new cylinder for a factory finish. You can see the difference with the original head finish.

Back to work! Brand new parts is a never ending game. Today brand new cylinder size "C" and a silencer frame mount. Order in progress : Original piston C, rings, pin, clips Brand new magnesium engine covers

Today, Piston, rings, cylinder, clutch, selector, clutch arm, carburetor gaskets, spark plug, intake pipe, valve box, cylinder head, air box rubber, rear frame: new original! Used air box in good condition. I ordered clutch and throttle cables. It feels good to be moving forward, but I still have work to do. It took me quite a while to gather the parts for this machine. When I compare it to the TYZ, there is a world between the two. The Yamaha was much more modern in design and manufacturing. This 311 was really the “before” Honda engine.

ITALKIT CONROD.

I'm waiting a new conrod to finish the engine. All new bearings, seals, original piston Gilardoni, original new cylinder, new rings, new clutch ... all new engine ! 🥰

38 pilot jet right. 3.5 turn fuel screw (original 35) The replacement air filter foam is “lighter” than the original Montesa. The engine therefore breathes much more air.
