    fork oil

    Hey Cats. Me again. Suzuki manual states "Suzuki #15" fork oil. Assuming this means 15 weight oil ? Am I correct? Also any thoughts on synthetic fork oil vs conventional? Thanks again Cats appreciate your help

    I can not guarantee that is what they meant, as they might have had numbers that really meant nothing in the real world.

    Also note that some manuals had you mixing 50/50 ratios of 30w engine oil and Automatic Transmission Fluid.

    In today's situation, many will be running 15w fork oil, with good results. Since you are changing the oil, is there any chance that you have replaced the springs, as well?

    SPRINGS are what really makes the difference in the ride. If you replace your worn-out 30+ year old springs with something that has enough oomph to actually hold up the front of the bike, you could even use 10w oil for a nice, smooth ride that also keeps the front wheel on the ground.

        Thanks, Tom. Not sure if that is the report that I saw several years ago, but some time back, I learned that oil "weights" are not consistent. That article mentions that one company's 7w is actually lighter than another company's 5w, which shows the importance of picking an oil, then sticking with that company when you decide to make any changes. Hoping, at least, that their line of oils relate to each other, if not to those of other companies.

        As an example, if you have BelRay 15w now and want something lighter, a move to Maxima 10w might not get you what you want. Maxima 10w might be close to BelRay 15w or it might be close to BelRay 5w. It might even be close to BelRay 10w, but you really don't know, so stick with BelRay and eliminate at least one variable.

          This is something I didn't realize, thanks for the tip.
