Question about 2006 Yamaha Road Star Midnight Silverado

1 Answer

I have a 99 roadstar that I bought. Impressive bike but has a knock that has developed when under load. I had new oil put in when I got it, 20w-50 castrol. Put 1500-1600 m. 1500 plus Km on it since last oil change. Ride for 20-25 min before it starts to knock under load. keep riding and it gets worse, but still only knocks under load. I am afraid to ride it more dure to possible damage. To me, it sounds like a possible rod bearing, but I am not a motorcycle tech, just a car tech, but the rules are still the same

    Just clarification please, does it only start to knock under load after 20-25 min and not when it is cold?

Camal engine. pls kindly help me type of diesel oil to use for my below engine camal ! Model 178 weight 33 maxout put 4.04kw(5.5hp)/3000rpm 4.41kw(6.0hp)3600rpm replacement 0.296l air cooled diesel...

the make CAMAL is new to me but it will use standard clearances as any other diesel engine to be reliable. The viscosity you name (20W--50) would cover most operating conditions where the ambient temperature ranges from 15 degrees C to 80 degrees c. Diesels have to operate with at least 80% load or they tend to glaze up the bores and blow smoke. The oil you name is a single grade oil and should prevent this problem but multi-grade oils will do the same if kept fully loaded . The brand name will be irrelevent as the viscosity is what counts.

I've just dumped the old oil in my 1972 cb350 twin. I've just bought Penrite 20w-50 to replace it as a friend advised me this is the best, another friend told me I should have bought 10w-50. The manual...


Just as long as you don't use any synthetic oil products, you can use 10W-40 or 10W-50. I use 10W-50 during the summer months and 10W-40 during the winter months.

Synthetic oils are not made for old bikes and will most likely cause damage to your bike, especially your clutch system.

I hope this helps. If you find this information useful, please vote on this post. Thank you.

What oil do i run in my yamaha roadstar silverado

Any oil that is JASO MA certified motorcycle oil. 10w-40 for cold climate. 20w-50 for warm climate/touring. Car oils use different additives. Do not use any oil that says Energy Conserving on the label . It will shorten the life of your wet clutch and transmission gears. If you use Synthetic oils, they will help your bike run cooler and shift easier.

What grade of gas do i need to run and what kind of oil do i need to run in a 2001 honda shadow sabre?

Use any oil that is JASO MA motorcycle oil 10w-40 for cold climate 20w-50 for warm climate/touring. Do not use any oil that is Energy Conserving it will shorten the life of your transmission gears and wet clutch. Synthetic oils will help your bike shift easier and run cooler. Use the lowest octane fuel that will run your bike with out pinging/knocking. Probably 87 or 89 Octane it will say in your owners manual. Ethanol may cause knocking/pinging on some models. No ethanol will definitely help in vintage 70's motorcycles

What is the weight of the final gear oil for the suzuki boulevard M50? Is it 20W-50 gear oil?

NOOOO! Do not put 20w-40w in the final drive!!!

This bike has hypoid gears (beveled gears that create a sliding action across the teeth and therefore energy loss and a lot of heat). A 20W-40W oil will destroy those gears, it can't handle the high friction in the final drive.

You need an SAE90 Hypoid gear oil with a GL-5 rating as defined by the API (American Petrolium Institute) classification system. If you operate your bike in temperatures less than 32 degrees F (0 degrees C), you will need to use SAE80 GL-5 Hypoid gear oil.
