+MotoConner Theoretically if you use synthetic oil the oil will not break down as fast than non synthetic, therefore giving you more time to not have to change the oil. But I still change my bikes oil every 8-10 hours of riding, and that is about 1-2 full days of riding.
You should be able to pull the choke out all the way and it should pop into a wide open position, if not you may need to go through and clean your carburetor
Just a warning to all of you: DONT USE A 10+ pound torque wrench on the 7lb bolts. Unless you want to spend a whole day getting a snapped bolt out of the crankcase cover ;)
+Jake Robbins, When I buy oil I look at the oil requirements found in the service manual, then I go to Walmart and Match the oil requirements found in the service manual to the oil available at the store. The motorcycle oil was there but the atv oil was less so I bought that, Lots of people pay a premium when buying oil thinking one is better than the other, but as long as it meets the oil requirements there is not much of a difference. But if you are comparing conventional vs full synthetic oil, there is gonna be a big difference. Comment back if you have any more questions.
The recommended engine oil is "Pro Honda GN4 4-stroke oil" but other oils are ok as long as they meet the oil requirements, here are the requirements. 1.) The oil must be API service classification SG or higher JASO T 903 Standard: MA 2.) then they recommend the viscosity to be 10w-30 But where I live it is very hot and I run 10w-40 If you have a 150r service manual it is on page 1-6 under General Information. For that Valvoline motorcycle oil i would just check and make sure that it meets all the requirements, you dont want to damage your engine by using the wrong oil. comment if you still have questions.
It all depends on how hard, hot, and how long you are riding, if you are doing day long races i would only ride 2 day long races and then I would change my oil so thats about 10-15 hours of riding.
There are many different torque wrenches out there. I would recommend having 2 torque wrenches a 1/2 inch for big bolts like an axle, and then a 3/8 inch for other things you need. if you're going to be a lot of engine work i have a very small torque wrench that is very accurate and its a 1/8 inch torque wrench and it makes things easier
+The DazeMarksman i use lucas oil 10w 40 in my crf250r and lucas oil 80/85 for transmission but im not sure if the crf150 has seperate oils if it doesnt u just want the 10w 40
+Dean W The Crf150r has two separate oil chambers one for the clutch and trans and one for the engine. 10w 40 will work in both chambers in the bike but you can use different oil on trans if you want.
If u run the same oil in a 250r it should work, just make sure that you dont put transmission oil in where the engine oil is suppose to go. To be 100% i would check the manual
It does not matter What grease you use. You don't have to use grease at all, The grease is put onto the spring to keep it from falling off the oil filter when you are installing it onto your bike. I have had times when I change the oil filter and there is no grease left.
For nuts and bolts on a dirt bike some have a specified tightness they have to be to be effective. That tightness is measured in torque. A torque wrench tells you how much torque you have tightened a nut. I would say if your not using a torque wrench you have a higher chance of having a loose bolt or striped threads. So i would invest in buying a good quality torque wrench.
+Landon Richardson You can put 10w 30 and 10w 40 in the engine oil and transmission. But with the 10w 40 in the trans will make the clutch sticky when you are riding the bike while it is cold. To avoid this you will need to warm the bike up longer because the 10w 40 is thicker and it will take more time to lubricate the clutch when it is cold. But when the bike is warmed up it does not matter.
I know But it is Just a Precaution I take. Plus if you think that something is wrong with the engine you can cut open the oil filter and see if there are any clues to what is wrong.
Just dirt bikes thanks! I ordered one from my local Moto store and should be coming tomorrow night on there order. I really don’t want it to happen again though. Any advice you’d give so it doesn’t happen again because I’ve never changed oil and I noticed the o ring was kind of poking out of the oil filter cover after I tightened it then it snapped
In the manual it says to use oil to lube up the o ring but try using a little bit of grease over the o ring if the oil is not working, also if the bike is old and has lots of oil filter changes the o ring could be worn down and then it broke.
Just dirt bikes it’s not very old and the oil has probably only been changed a few times but I will try grease with the oil tomorrow when I fix it. I just really hope it doesn’t break again. Also I’m just not sure how the o ring started to poke out of the cover. I didn’t take it off at all, just put oil like you said so. Maybe I tightened too much?
It does not matter what the name is, if you go to the crf150r owners manual it has the requirements of the oil and the oil i use meets all of the requirements.
the bike only need 0.6 liters of oil ? isnt that to little, and i have a question, does anyone know how much recomended engine oil i would need in a honda xr100 1999 model? 0.9 liter ? or less?
i dont know the answer to your question, But I am pretty sure if your xr has one oil chamber it has an oil dip stick and you fill your bike until it is in the middle of the dip stick rating. If this does not make sense to you dont try it and use the honda oem service manual to help you out.
+Delta Gaming How often you change your oil depends on... ---> How you ride. Hard, Medium, or easy. How often you ride, Long time, or short time. and where you ride. Dusty, muddy, or clean. I trail Ride and I am in rather good conditions clean or a bit dusty. I ride about 25 miles in one day. but I am riding easy. I change my oil every 2-3 rides. That is about 50-75 miles per oil change. If you are Racing or and riding hard I would change it every day you are going to do that.
With my bike I use cheep oil non synthetic and change my oil every 50 miles, Both trans and engine. If you use more expensive oil you can change it less but the dirt stays in your engine longer. I would say use cheep compatible oil and change it more. But the decision is yours I do this and my oil looks like the color of card board, when i change it looks like cardboard but a little darker.
The oil i use in this video is what i use for both engine and trans it is compatible. This oil is not synthetic and breaks down quicker than synthetic oil. but it costs less, so I just buy the cheep non synthetic oil and change it very regularly. This is all on Crf150r
