'80s Domestic famous car / Yamaha RZV500R Complete Maintenance [I want to overcome aging and maintain it]

The famous cars of the '80s that are still extremely popular.What should I be careful about to enjoy the run, which is a lump of personality, and what kind of maintenance should I do?We will clarify the weak point in maintenance for the highest peak of the Yamaha RZ series, RZV500R, which has changed history.

[Cooperation for coverage: Moto plan] Moto plan found in '78 is a new and old Yamaha specialty store.For more than a dozen years since the mid -1980s, YSP signs have been raised, and new cars have been sold since then, but recently the old car has become the main.This time, I heard about RZV, but there are many warehouses such as RZ/RZ-R/TZR/FZ/FZR/XS-1, regardless of the engine format and year, regardless of the engine format and year.● Address: 5-7-30 Maehara-cho, Koganei-shi, Tokyo ● Phone: 042-385-6511 [Expanded with photo tap]

If the peripheral parts are normal, will the burning happen?

Speaking of a two -stroke car in the mid -1980s, everyone would first think of the piston and cylinder.In fact, it is not unusual for RZV to enter the Moto Plan, but the cause is that there are many cases where peripheral parts and how to ride.

"Oil pump is poorly operated, oil delivery pipe damaged, poor oils, clogging of carburetors, overheats such as overheating due to reckless driving (not only maintaining high revolutions for a long time, but also NG driving in traffic jams).There are various causes of the relationship. Unless the cause is identified, baking cannot be resolved. "

Other than that, the overflow of the carburetor / crankside seal due to the defect of the rust / fuel cock in the gasoline tank, the damage of the water pump seal, the regulator lecto fire punk, etc. are often heard in RZV.

"Such a problem is not limited to RZV. Regarding the regulator lecture fire, Yamaha cars at the time were certainly troubles, but the causes of other problems are all aging. Conversely, conversely.If you replace the deteriorated parts with a new one or in a proper state, RZV can be enjoyed with a sense of maintenance -free. Unlike modern motorcycles, the amount of 2 streets and the small size battery status.I need to check it for beans. "

Cylinder & Piston: Can be played with over size piston and bowling

[Cylinder different in front and rear cylinder] Cylinder contains traditional cast iron sleeves.The left is for the front two cylinders, and the right is for the rear two cylinders.Structurally resembles the TZR250 (1kt)/RZ250R, but it is not a design that considers compatibility.Carbon tends to accumulate around YPVS with exhaust port.[Enlarge with photo tap]

[Create a different baking piston] Baked piston.In the past, when one cylinder was burned, it was basically a piston replacement/bowling, considering the balance, but recently it seems that there are cases where only damaged cylinders are repaired according to customer requests (in the first place (in the first place.There are many individuals with piston size different at the time of arrival).[Enlarge with photo tap]

[Genuine piston is the best if you are reliable] Over -size genuine new piston stocked by Moto Plan.This is also for the left two cylinders on the left, and the right is for the rear two cylinders.In recent after -market markets, various manufacturers in Japan and overseas sell repro pistons for RZV500R, but only genuine is used.[Enlarge with photo tap]

Crankshaft: Side stickers and bearings are consumable parts

The crankshaft is an assembly type, and the store has been working on many overhaul / core.The leading consumables are side seals and bearings, but recently many individuals have damaged crankpins and connector.[Enlarge with photo tap]

Read valve: Make genuine alternatives by processing for other models

Although the mounting position is different (front: crankcase, back: cylinder), lead valve + housing is common to the front and rear cylinders.Since the genuine (left) is already out of stock, Moto Plan is processed by processing the genuine model of other models.[Enlarge with photo tap]

Carburetor: Maru Piston VM leading to RZ/RZ-R

The carburetor is a round piston Mikuni VM26SS.Gaskets and seals can be obtained by genuine, but throttle valves and jet needles are out of stock.As for the carburetor, a repro product may be used in the moto plan.[Enlarge with photo tap]

Fewel cock: The internal diaphragm deteriorates

The fuel cock is a negative pressure type.The deterioration of the internal diaphragm causes the overflow of the carburetor.When the right carburetor overflows, the fuel may enter into the crankcase, causing a water hammer -like phenomenon.[Enlarge with photo tap]

Spark plug: Nut loosening leads to malfunctions

The genuine NGK BR8HS (right) has an integrated terminal nut.You can use a separate body, but be careful when loosening the terminal nut that causes the engine malfunction.The Moto Plan sells an integrated set of 10 for 5000 yen.[Enlarge with photo tap]

Oil pump: Be careful of poor operation of the main unit and hardening of hoses

The oil pump is installed at the top of the mission.When a foreign substance is bitten into the internal check valve, the appropriate amount cannot be supplied to each part.It seems that there are very many slender delivery pipes that are ticking due to aging.[Enlarge with photo tap]

Water pump: Mission oil is coffee culmination?

The problem with the water pump is the seal on the back of the impeller and the case cover.If this part is damaged, cooling water and mission oil will be mixed.Similar troubles are likely to occur in RZ/RZ-R and TZR.[Enlarge with photo tap]

Radiator cap: Decreased pressure resistance develops overheating

Although it is often neglected in the world, the radiator cap is an important part that functions as a sealed valve/pressurized valve/negative pressure valve.If the spring and rubber deteriorate over time and the pressure resistance decreases, it is more likely to overheat.[Enlarge with photo tap]

Recovery tank cap: Eliminates leaks with new caps

Radiator coolant and 2 -strawberry recovery tank caps often break due to aging.Motoplan, which considers this part as a consumable item, always stocks genuine new products.The price is 3000 yen.[Enlarge with photo tap]

Front fork: Consider changes to other models

Forks with different inner tubes depending on the part, an air valve and equalide dotube (photo) are installed at the top, and the anti -nose dive mechanism is installed at the bottom.Overhaul is possible, but many people change the store for Yamaha cars later.[Enlarge with photo tap]

Front brake: The best measure depends on the rider

The front and rear calipers can be overhauled using genuine parts.However, there are many people who change to 4 pistons for Brembo and Yamaha cars in the later year, with the awareness of improving braking power.For the vehicle in the photo, the disk is for RZ-R, and the anti-nose dive is canceled.[Enlarge with photo tap]

Rear shock: Nightlon and Orleans are standard

The rear shock is a horizontal mount under the engine.At that time, Yamaha was looking for various mount methods at the YZR500.Some geeks are particular about genuine, but Moto Plan often changes to Nitron and Orleans.[Enlarge with photo tap]

Rear disk: repair and custom with wave disk

The front and rear disks of the ventilated type, which were classic high -performance cars from the early 1980s to the middle, were already out of stock.Moto Plan prepares a rear wave disk that is repaired and customized as an alternative.The price is 13,200 yen.[Enlarge with photo tap]

Tire: Recommended traditional K300GP

The genuine tires are biased, and the size of f = 120/80-16/R = 130/80-18 is a special category even if you consider the standards at the time.The recommended Moto plan is Dunlop K300GP, but Bridgestone BT-46 also has a suitable size.[Enlarge with photo tap]

Electric parts: Ignid -based alternative parts and power generation -based measures

On the left is a CDI unit developed by the Moto Plan, and the map of the ignition time and the opening and closing timing of the YPVS can be adjusted arbitrarily.On the right is a regulator lecture fire.The upper with the word 47x is engraved, and the lower part is a genuine countermeasure.[Enlarge with photo tap]

Main harness: Uses a reprinted version handled by high side

The main harness is already out of stock, but a high -side activity, which specializes in the electrical system, produces a reprint.The standard specification type 00 is 47,360 yen, and the type 01/02, which has been changed to a fuse box to a modern configuration, costs 53,80 yen.[Enlarge with photo tap]

Battery: Check the amount of liquid for beans because the capacity is small

The battery arranged to avoid the rear cylinder chamber is an old -fashioned open type.Since the capacity is not enough, I want to check the beans for the liquid.The Moto Plan does not recommend changes to MF type or lithium.[Enlarge with photo tap]

Part distribution: Not desperate but not optimistic

Although the structure of the engine leads to RZ-R/TZR, RZV is designed for most parts.Moreover, the production period was short and the production volume was small, so the supply status of parts was quite severe.

"In the case of our house, we are stocking a large amount of new / used parts, and the method of diversion of other models is established, so we do not have to worry about repair or get lost. But general used car dealers.If the private or a private bike plays this bike, I think I'll hold my head everywhere. "(Mr. Kawahara)

[Gaskets are the key to engine overhaul ...] Some gaskets, which are the essentials of engine overhaul, are already out of stock.In the after -market market, repro products are sold, but Motoplan uses genuine products that are as reliable as possible.[Enlarge with photo tap]

[Single seat cover that tightens around the rear] A FRP single seat cover made in the store that faithfully reproduces the style of genuine options.The painted complete kit costs 74,000 yen, and the gel coat finish/no pad is 27,500 yen.[Enlarge with photo tap]

[Under cowl is slightly extended before and after] under cowl, where Moto Plan is currently developing.Although it follows the genuine style, the material is FRP and the front and rear length is longer than normal.Bolt -on, of course.[Enlarge with photo tap]

[Decal with fading] The store produced a decal set with silk printing with less fading in order to respond to the request of the RZV500R owner who loves normal look.The price is 11,000 yen, and it does not sell roses.[Enlarge with photo tap]
