Most Honda's use ATF which is the equivalent of 5 wt fork oil. The heavier the weight of the oil the stiffer the front end will be reacting to the road. 10 wt oil is very popular for most riders. 15 wt or 20wt is typically used in heavier bikes or with heavier riders who are looking for a stiff ride. Use the recommended weight so you don't change the handling characteristics you are used to. Try a bigger Yamaha dealer I can't believe Yamaha does not sell a specific and overpriced product for your machine . The other dealer did not want to buy a whole case just to have some on hand.

I have a1974 FLH front end with 2 in. over stock tubes. What weith oil and how much sho uld I use in each fork. This front end is on a all steel (1000lb) VW Trike.


The service manual says to add 7 ounces of Type "B" oil to the "dry" stock tubes. I'd probably try 7 ounces of PJ1 30 weight oil in that machine to start with. Then, you may have to adjust the quantity and oil weight to get the ride you want. From my past experiences with these types of machines, the biggest problem you're going to have is lightness in the front end. They will "wheelie" very easily and may even "hop", front wheel bouncing, when going down the road in extreme cases. It may turn out that you need more damping action in which I'd try the "wet" quantity of 6 1/2 ounces of 20 weight oil. The "wet" or "dry" quantity means that if you took the fork tubes apart and all the oil is out of them, they're considered "dry". A simple drain and refill is considered a "wet" oil change. I think Honda actually offers a 25 weight oil. I've seen fork oil weights available down to 5 weight. You'll just have try it and see what it does.

Good Luck

In changing 2005 Harley Heritage Model FLSTCI fork oil, how many ounces of fork oil should I use? What does wet or dry mean?


I'm sorry but I don't have the specs on the quantity and type of fork oil for your year and model bike. I work on the older bikes that the dealers will no longer service. But, I can describe the difference between the "wet" and "dry" conditions of the fork assembly. If you take the front forks apart, clean them out, and put them back together with no oil in them, they are considered "dry". For a simple drain and refill type oil change on them where you don't get all the oil out of them, they are considered "wet". I hope this helps, You can call you local dealer's service department and they should tell you the quantity and viscosity of the oil that goes in the front forks on your machine. They'll tell you something like 6 ounces of "Type E" oil, for example. Harley-Davidson uses these types of specs to describe their oils. If you go to a website for fork oil, like PJ1, they may give a cross reference or equivalency chart for converting H-D "Type E" to their oil. I think that would be their 30 weight oil. If the front end seems too "stiff" with 30 weight, you can drop down to 20 weight. I think Honda makes a 25 weight but not sure. Your Harley won't mind the Honda oil. BG.

Good Luck

My 2011 fat bob has a lose of power when you let off throttel the front end dives


Since your bike is a 2011 model, I'd take it to the dealer and let them check out the loss of power. On the front end diving, you may need to put a heavier viscosity oil in the front forks. You'll have to drain the forks and then refill them with the proper amount of oil of a heavier viscosity. I think the forks come with H-D type "E" oil that is supposed to be about 30 weight. Use only "fork oil". You cannot use engine oil.

Good Luck

My forks just dont have enough resistance.


This is an old thread but just in case you haven't gotten the problem fixed, you need to change the fork oil in your forks. The main reason is to make sure you've got the correct amount in them.

If after changing the oil they're still too spongy, you need to change the oil to a heavier weight oil. Use 30 weight "FORK OIL". Do not use any other type of oil as it may foam. Use fork oil only and in the correct amount. Your owner's manual should tell you how much oil to add.

To drain the oil, there is a plug down near the axle on each fork slider. At the top triple trees, there is a large cap on each fork tube. Take this out and add the proper amount of the proper weight oil. Only do one tube at a time. You may have to get the weight of the bike off the front end.
