I understand how to measure the proper amount in the forks (space, not volume) :glare: . My question is how much to buy. The service manual specifies approx 23 oz is required for my 06. The question I have is: Is that per fork or for both forks? The Yamaha 01 Fork Oil sells for about $35/quart. The Ohlins R&T43 sells for about $55/quart. If it only requires 1 quart for both forks, I'd rather not invest an extra $33-55 so it can sit in my garage for the next year or two. Thanks
PS I'm asking because the dealership is clueless
You will need slightly more than a liter of fluid to do both, in most cases. Volumes vary some. However, you
will need two liters to ensure that you have enough to use some to flush out the fork tubes before doing the final fill.
FJRTech article And trust me, you do want to pour some in and work the tubes, then dump the nasty stuff back out before you fill it with fresh fluid!
And those prices are obscene! Go get some Silkolene or BelRay. Most seem to like the 7.5 wt. Silkolene or the 10 wt BelRay. I used the 10 wt. BelRay w/o problems. My skinny friend used the 7.5 Silkolene and liked that. I bought BelRay for $10/L and the Silkolene Race for $12/L. Forget your dealer, he's a Pirate! Even the Yamaha 01 fork oil is way cheaper at my local dealer and it's 5 wt, FWIW.
