that's just his way of doing it,theres plenty of links showing otherwise.
better tell him to read point 12 in this pdf from progressive suspension.

Feel free to tell him yourself mate.... ;D ;D 8)

Some only read what they want too see at times.  ::)

Warning: [/b]Always make sure that the damper rod is covered with oil when the forks are fully extended. If there is too little oil in the forks,
they will run out of oil before full extension and result in excessive topping out. If you continue to ride when the excessive topping occurs the
forks could be damaged enough to result in fork breakage leading to an accident and injury.


Just sayin'

Is there anything more fun than riding? They are between your legs and are quiet when you turn them off.

This was from YOUR link Dave. Are you truly that misguided? If YOU wish to operate a system outside of its design parameters... go for it. (Don't involve any innocent passengers please.)
YOU apparently know so much more about the design in question than the ENGINEERS that designed it.  ::)
Perhaps YOU should contact those ENGINEERS and set them straight.  ::)

you still don't get it eric?you can run less but not excessively,like if you run it so low the damper isn't covered fully,theres no problem using slightly less oil,retro seems to think itll bottom out early with less?you still haven't found anything for us all stating you must never ever run less as its way wrong,its a done thing not a naughty no no,lighten up.

heres a copy paste from some site,

I've never used transmission fluid in forks. I mean why? There are so many dedicated fork oils available?
I'm a Bel-Ray fan too OWD.
Other than that, I guess the real question is, how do they feel with that oil when riding? The weight of the oil will change the way your forks respond, which also depends on riding style, bike, and rider weight, etc. That's why it's advisable to use a dedicated fork oil that you know the weight of as a starting point.

As for 'pegaxs'... if you cant find the info in a manual, then bleed the forks and measure what comes out of each tube. As accurate as you can. Then use that information as a guide, not a guarantee, but consider it a starting point concerning measurement.

Remember the response of the forks can not only be tweaked by the weight of the oil, but also the amount of oil you use.
Keep the level of each fork tube exactly the same, as best you can.
Use one of those horse-like syringes to add and subtract.
Ride, test, and tweak...

Ok guys, this thread is settled right here....cus I know forks work fine when they are low on oil, how do I know? ...every bike I have ever owned had severely leaky fork seals when I bought them, and you could still ride 'em just fine....done.
If it works good, it looks good...

My left side fork has been leaking for 6 months .Not once has it bottomed out. Not worried in the slightest. Got other things to concentrate on and fix before i loose sleep over a weeping fork seal. Oh my god. The oil level is slightly less than the spec sheet lists. Big whoopy do.

Chris, you may like to tell us all what you actually know about suspension {or motorcycles in general} that brought you to that conclusion mate..?  I've experienced the exact opposite to you so,  without having much experience with motorcycles what so ever i find that comment contrived and only there because you spoke to Dave while he was working on your bike and chose to have a dig rather than add something helpful based on relevant information. I wouldn't actually boast about riding round with a blown seal for 6 months either... :o, and "whoopy do" isn't a technical term ....  Dave, I don't seem to think they'll bottom out earlier with less fluid, its a fact that they will depending on the oil level and of course things like sagging springs and you know that, poor choice of words maybe. Now, since things are getting all pissy, it might just be time to leave this as i said earlier and just agree to disagree, Dave won't change his mind and neither will Eric and I. Everything in this thread that needs to be said has been and anyone bothering to read it can make up their own minds, all good people here so lets move on.... ;)  Merry Christmas to one and all....

might not be a bad idea mick?just out of interest ive never used the measured height method to fill my forks,so today I thought id crack a beer and tinker about,it was that or mow the lawn,i measured mine and have 180mm(7 1/8 inch)spring removed,these are 500 forks with the damper rod,i then drained the old and have 150ml,i never measured the refill just replaced 150ml fresh oil,the spec for these is 155-165 ml so its a bit variable anyway?

it was about 18 months old anyway.

Thats far from the worst condition oil i've seen in a fork Dave... ;)

Mick, what i know about motorcycles in general is limited as I'm new and learning every day. Is your question a dig at me? How i got to that conclusion is very simple Mick. I have experience with my bike because i ride my bike a fair bit. It's basically a daily for me. I know how it feels. A little leak doesn't effect my bike. Thats my conclusion. Yes its opposite to yours. I added my experience from my bike.

The more it looses than yes my chances of bottoming out are higher. I know that. And yes i was taking a dig because 6 pages of chat about this is ridiculous.

Your previous 2 posts were either while you were at Daves while he was working on your bike or when you'd arrived home..?
How is it ridiculous to you Chris.?  You know virtually nothing about your suspension, how hard do you brake ?, do you even know the limitations of your machine yet.? I know you are getting to know your own limitations,  but what about the bike..?, Experience is something earned over a long period of time, i wouldn't claim to be experienced with your limited time in the saddle, and I say that with no disrespect what so ever, just pointing out what I know. I have bottomed out a motorcycle front suspension and if it happened to you in traffic in the middle of the road you would clearly understand everything i've said, I was lucky enough to do it at slow speed under full brakes as I entered my driveway , actually I had a couple of smaller bottom outs previously on the same bike but the last one nearly broke my wrists as i've previously stated. I bought my first 750 Honda at 16 years old, I got my car license at 40 years old, for a very long time bikes were my sole transport means {had around 35/40 bikes of all types} , I modified my bike suspensions from the second bike I owned , my mate and mechanic {Harry Hardstone...real name ;D} raced them , schooled me on what to do and introduced me to Russ Collins high performance parts, His boss and shop owner was Peter Rice , a life long friend up until his death. I bought my first RC crank and rods at 18 years of age from Harry,  I've been around high performance bikes most of my life, I am a suspension nerd, always have been,, and worked in a well known bike shop in Sydney that had its own race team, and i'm still learning . Eric {750 cafe}is a mechanical engineer that builds hipo bikes {big GS Suzuki's}and knows his sh1t, he knows some very credible people as well, like the USA team captain for the period 6 historic race series hosted in Phillip island amongst others. You posted here because Dave told you what was being discussed, {Dave and I have been conversing by email and there was some piss taking involved}, you offered nothing to the conversation until then, so this thread was of no interest to you what so ever as are thousands of others, do you check every one of the hundreds of thousands of threads for ones you deem silly, theres plenty of them if you are interested...?   See my point now... Just calling a spade a spade mate, thats how i work, so does Dave. Everyone here has made their points, I love a good discussion but its over,   Now lets get back to the "merry Christmas one and all"....
