Bout to run to a local dealer to pick up fork seals, but they only carry honda brand fork oil. I have the 25mm ohlins carts in stock R6 fork tubes. Should I wait and order the ohlins fork oil or just pick up the honda stuff. Also what weight is recommended? Know this should be in tech, but need a quick answer before I head out, thanks.
Do you know who set them up originally? If so give them a call. Most tuners stick with the same brand of oil. Or if the oil was a specific color that may help determine what it is.
I have the service receipt from the original owner on my other computer, pretty sure it was ohlins. I just wasn't sure if the brand made a huge impact on how the forks perform. I'll probably just wait and order the ohlins then, thanks for the advice.
And to answer your original question I wouldn't put the Honda oil in there unless you need them back together right away and don't have anything else. It's almost certain that they weren't set up with Honda oil and fork oil viscosities vary widely.
