Dump & Run Motorcycle Fork Oil Change
on: March 01, 2020, 08:22:48 PM

As per above video I am guessing that this would work with Z900 forks, rather than going through the hassle of taking it all apart to do a regular oil service?

Anyone changed their fork oil yet? Dave recommends changing that about 5-6k mark but no later than 10k, opinions?

This reminds me, I'm due for my 2nd fork oil change...   :082:

Easy to do without needing to take the fork internals apart. Just the top cap and remove fork tube from triple. Measure what you take out, put back same. The right fork could be done for every 2x left fork change....but one oil container is enough to do both forks so why not. I don't like to keep oil for a long time sitting on a shelf (once opened container).

This is what mine looked like at 12K miles (left leg):



This is the new oil:


This is the oil I used because its slightly thicker than what comes on Z900:


For more info, use the search option, me and other have made posts on here before.

Edit: forgot to mention, not all 5w oil is 5w...not all 7w is 7w. This is why the selection of oil I picked was very specific due to other specs.

Thanks for the reply, I found the other posts about it as well  :028:

BTW once clamp bolts are lose will the fork slide out easy without scratching the black coating on it?

Kawasaki (KHL-10-15) viscosity is 15,3cSt@40C, this Maxima is 26.7cSt@40C.
Did that Change influenced rebound Setting, if yes, how many Clicks out is equivalent with this Maxima compared to Kawasaki (KHL-10-15)?

Thanks

I was wanting slightly heavier. I can't remember my settings after oil change...but I did change settings!

If one wanted the same dynamics as stock, Maxima 85/150 5w would be the proper oil to run (with 15.9cST).

As stated, the weight advertised varies wildly from what the actual viscosity is, and when heated. I use a chart such as what I hope this link shows. There's loads of such charts if you google them.
