Lovely video! Its nice to see the fork all the way taken apart. I never knew where the pistons were and the needles. Thank you very much!!!!

Keep em coming Dave!

These are so informative Dave. Can’t say thanks enough for your time in doing them. Looking forward to the ride review.

cheers for the share as always mate. cool.

Very educational. As usual. Good job.

Thank you for the pick / seal idea, i deed to do mine on my gen 2

Great suspension explanation Dave.

Interesting stuff Dave.

Great video, I had my ZZR1400 forks upgraded using the same kit, totally transformed the bike.

excellent video !!

I remember pulling the flywheel to replace the sprag clutch. I actually relived that same joy when you eventually took it off. 😁 Maybe replace the sprag clutch as well (with a KTM one, not the bloody expensive original one) now you're at it. Oh... man .... do I miss my V2 Tuono... 😖

Jusr realized i subscribed months ago but didn't hit the bell notification so now i have to watch every video to get myself up to date. Fantastic problem to have 😎 this channel is awesome and the reason I'll be giving Bitubo a shot on my next build for next season.

Thanks for positive vibes 😁

I had the same bike for over 4 years and loved it. Only niggle I had was the clutch losing pressure now and again, and a crap back brake.

You are definitely very good!!

I just swapped my stock forks for the sachs from a 2018 rsv4rr. Not a cart kit but a very good upgrade.

Really like your videos Dave! For that gentleman down below ,who states that you will demagnetize flywheel by heating it, I don't see otherwise how you can pull it of , without damaging it.While engine operating flywheel anyway choking easily up to 80- 100C° I assume.

Always a fantastic explanation Dave! Will you experiment with 10w oil on these forks at a later stage? What would be the effect? I can’t remember if you used 5w last rebuild?

@obsession_engineering

2 жыл бұрын

I always use 5w (unless the oem spec is heavier). Thicker oils tend to be less consistent over temperature changes and cavitate easier. 5w is pretty much the standard for race stuff for that very reason

Great explanation and videos always,did you lock your crank with a specific tool or bolt? if so which size thanks!

There is a crank locking bolt on the Rhs of the motor, modified m8 bolt worked perfectly

Do you think you could try to explain how adjustment effects feel on a closed circuit track, in different scenarios? Thank you.

Nice video. Would it have cost Aprilla that much to have the original suspension made to the K Tech spec? Surely even if they added £100 to each bike it would pay them in the long run to have a brand which had great suspension right out the box?

I'm sure they could have improved them for very little. But to be fair to them they aren't bad forks, I'm just fussy 😁 And of course they did the upgrades in the factory version

Just got my first 2007 tuono and thinking about upgrading the suspension with the k tech kit. How do you fit the rebound needles in to the end of the rods, you mentioned cutting the ends of the rods off but it’s not in the video. Thanks Dave

Cracking bikes! The engines are strong. The charging system is the weak link. The later bikes had most of the niggles fixed and a lot of the earlier ones will have been upgraded by now. The fuel tanks can swell if cheap fuel is left in too long. Nothing too scary really, especially for an Italian

when you were doing the pushrod seal do you remember what the criteria for the seal was? I'm looking to replace mine but here in America they are very hard to come across, we have lots of generic stores though.

I can't remember the exact seal, but it will be marked on the existing seal and can be cross referenced from the part number

​@obsession_engineering Good day, did this actually work and is the stator still happy with that mod? Is the mod working and do you perhaps have info on using the series R/R instead of shunt? I would like to beat this issue with my bike as the stator is burnt out again.

After taking about three dozen of these off, I would say that one would be in the poped off easy range.

dave please i have a question . im doing valves for the first time! my question is my clearance is 0.13-0.15. i can fit a 0.10 -0.15 .and a 0.20 there is more resistance but it still fits. so my question are my valves still to loose sinces i can fit a 0.20. sorry for my noobest lol. love love your videos thank you for all you do !

@obsession_engineering

2 жыл бұрын

If a 0.2 fits, but is tight, I'd say the clearance is pretty much 0.2, so a bit loose if its supposed to be 0.15. .13-.15 seems a very small tolerance, if it's ducati I'd check if there's an 'in service' tolerance as they're sometimes bigger than the 'build' tolerance
