New ergal parts 70grs less than OEM steel parts.

First observation about the Mitani aluminum clutch. It perfectly releases the transmission when disengaging. The neutral selection is excellent even when cold and I can significantly lower the engine idle speed.

Carbon headlight ... so much better than plastic.

-57 grs ...

Assembly of the 2nd delivery of titanium screws: -125 grs Mitani aluminum clutch assembly: -250grs Currently dry weight: 74.125kg With a machined flywheel and a Michelin Xlight I can remove another 1kg. The factory bikes around 71kg (much more magnesium ...)

Don't worry, I love my torque wrench.😎

When reassembling the casing, I apply a little 15w50 oil to the inside of the cover with a brush in order to seal off the interior surface from oxygen. It is made of magnesium and this alloy oxidizes easily to end up in powder form.

Subtle detail, the ex-factory ignition cover from Banyeres. ... It is only different from the original by its lighter color than in the series. I still need a few titanium screws to put everything together.

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

Mitani alloy clutch kit -250grs

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.
