Glad you corrected yourself re ruler and rule...my late father was an engineer and always reminded me of that when I was using my rule for homework. I've never forgotten and I'm now 66!!

[@markchisholm2657]

I'm an engineer and use a 'rule' not a ruler. Or so I thought. I had the discussion a while back saying a rule is used by engineers while a ruler is a school child's device or someone who runs a kingdom. Turns out I was wrong. Ruler is in fact the correct term although rule is often used by engineers as well.

[@obsession_engineering]

I'll have to do more research on this 😁

Getting set up to do fork service on my Ducati Paul Smart. This is by far the best and cleverest (with the entertainingly tongue-in-cheek off-color puns) video on Ohlins fork service I have found. Especially appreciate the plastic bag trick. One video suggested going over the inner tube with 800 grit sandpaper, made my skin crawl. I could see 1200 grit but not as a matter of course; only if needed.

[@steveball2307]

Interesting to see the thought Ohlins have put into the design to make the forks straightforward to work on.

[@jonathanmackie4884]

I have a new appreciation for your Blue Peter inspired presenting style now Rob pointed that out. It really works for me. And the use of Rob on camera holding duties during the action shots really helped too. Rob has many talents it would seem.

Double entendre Dave on a Monday….what joy…👍😜👌🇮🇲🤣🤣🤣

[@martinowl]

A good clear demo on those forks. Makes it look so easy.

[@gezkemp1263]

I’m setting about this this weekend with aid of this video 👍

[@siddarthchandran6201]

Excellent job. ! I had been searching for a while for exact OHLINS service tutorials because am planning to get the MT 09 but was quite hesitant to choose between the standard or SP version that comes with these ohlins setup. Dunno whether we have proper servicing bay for premium suspension setups in India. And the bike being a CBU unit here, it’s pretty much hard to get serviced for the top quality components fitted on MT 09. Still not sure whether I would go for the SP version or the more standard one. But definitely you educated well on how these parts should be taken care with proper tools and consumables on a proper work bench. Can’t thankyou enough. With much ❤ and respect from India

[@obsession_engineering]

If you can find someone to service the suspension, I'd always go for the better spec bike, it really does make a difference

[@gezkemp1263]

Did the job today and you were so right it’s quite easy and just did it with 1 litre of oil but bought two in case but will do if I ever do them or another set again 👍 longest part is awaiting oil to drain and taking forks and putting back in again don’t have a lift so up and down off the floor and don’t have s front stand so jack under sump and I have a Ilmberger belly pan so remove that is quick but again thanks so much for the detailed video it’s so helpful thanks again

[@obsession_engineering]

Glad you found it useful 😊

[@mattmid7012]

I thought for a moment at the start of the video that you'd become crew chief in your own workshop and was having Rob do all the work. 😂 Now there's an idea... I think I won Dave Innuendo Bingo after about 11 minutes.🤣

[@obsession_engineering]

Now there is an idea 🤔

[@robertyork4041]

Innuendo workshop with some technical stuff thrown in...superb 😂

[@RushEvoHD]

Thanks for the Informations 🎉

[@danielmorrill3164]

Much difference between 5W fork oils? K Tech is 17.5 cst at 40 degrees and Ohlins is 20 cst I believe. So around 10% change. Will be interesting to see if the forks feel any softer as a result, bearing in mind that he maintained the same number of clicks...

[@Mattster0802]

Great video Dave, though you spoke so quickly it sounded like you were massively over caffeinated! Also - you’re a naughty boy for dumping oil down the sink-Ha! Motivated me to get the forks sorted on my M900… Cheers from Florida!

[@obsession_engineering]

The sink isn't connected to the drain

[@anfieldroadlayoutintheloft5204]

Great video on channel keep up the great video s

[@gezkemp1263]

Thank you 🙏

[@matthorler4613]

Properly helpful :) A++++++++

[@keysersoze3866]

Great video and well explained. Could I please ask what size cap top tool you used? I measured it at 50mm but there is also a 48mm tool. knowing my luck I will get the wrong one. I've looked at the number stamped at the bottom of the fork leg but I can't find a tool to match that up. FL9210 2015. Thanks.

[@gezkemp1263]

Thanks again Dave for a spot on video 👍 just a question Would a litre of oil do for both forks and do u need to wind all the preload rebound and compression off before you start after taking settings that were already in the bike ?

[@obsession_engineering]

Dampers can stay where they are, I'd always remove the preload as it'll make disassembly easier.

[@obsession_engineering]

And a litre will just do the job, but only just!

[@ianlawrie919]

Most enjoyable, great camera work for a guy desperately trying not to pay any attention to the man talking 😂😂😂😂👏👍👌

[@flatgrindrides]

😂👍

[@gonzosk8966]

The glory of British Innuendo 😉

[@stephenlebillon3066]

First click is 0, that is a great tip to get accuracy.

[@kawi704racing]

Cool.

[@SuffolkZX]

Everyone needs to tickle their nuts once in a while, thanks for the vid and good luck at Thruxton.

[@mecawenl]

do you know if the inner tubes are pressed on the brake caliper carriers? or are they removable?

[@obsession_engineering]

They're screwed in as far as I know

[@mavrik11964]

When reinstalling the spring cap locknut how far down do you wind it i.e is there a specific amount of threads that need to be visible before the top cap is screwed on?

[@obsession_engineering]

There's no measurement on the Ohlins, just screw it until it stops

[@mavrik11964]

@@obsession_engineering cheers for the prompt reply 👍

[@mikefry6765]

Will the new oil mean you have to do the setup again as the old settings were when that manky yuk was in the fork and I imagine less viscous than the new clean oil ?

[@obsession_engineering]

The base setting from aprilia was for when the forks were new, so I'll stick to them as a start point. And it's an interesting test to see if the difference is noticeable

[@bamzager]

This should be rated 18+ 🤣

[@chr11sf]

👍

[@kennethszpindor1723]

Just a quick question do the suspension company you deal with do a good suspension for a moto guzzi 7v stone 850 se could you let me no dave cheers

[@obsession_engineering]

Hi Ken, can you drop me an email to [e-mail] with model and year please and we'll see what's out there

[@RustyVanDoor]

If Rob has a speaking part do you have to pay him?

[@obsession_engineering]

Dear lord no!

[@Red-74-]

Not a semi-active service technician about if its not ohlins. The calamity when other manufacturers semi-active suspension is woefully under damped because no one will service them and if they do its guess work🤣.

[@joshowens65]

😂😂😂

[@VaBraAnton]

Is there something wrong with the video? It seems to me like it is choppy and at 15 fps or something

[@mikefry6765]

Blame Rob

[@obsession_engineering]

Definitely 30fps, so could be your end

[@flamintasty]

Bloody marvelous, old chap (insert Sherlock Holmes pipe emoji here)
