Pit bike forks are not the best anyway. But I did spend the time to get my springs rated and then worked on having the correct springs wound for my bike. I sorted out the fork oil and I know the damping in my forks does make a difference with each click I add or subtract. I even had the rear shock spring correctly rated for the bike and the 1000lb spring then the "recommended" 800lb spring was junked for a 450lb spring and then the pre-load was now able to make a difference and not just rock hard on the swing arm linkage rate on the bike. Not bad for the Ti Nitride FastAce forks and the DNM Hornet with the high and low speed compression damping.
@@Pitbikesonic76 The modded FastAce forks do work over most of the adjustment range. They did need thicker oil but the biggest thing was rating the springs and changing the spring rates specifically for the bike. I had 20% and 30% stiffer springs for the forks. Tye Kinton and Lee Jackson wanted to try 30% stiffer forks. But having the options of 20% and 30% actually gave us 10%, 15%, 20%, 25% and 30% by mixing and matching the springs. The last time I took the bike out Rich Cooper also tested it and said it was night and day different to what he had ridden before with 15% fork spring change and we Just needed a couple of clicks on the compression and rebound damping on the front. The Ayrton using Ti Nitrided stanchions stopped stiction so the front end now actually feels like it is working and you can make the bike do what you want. The rear shock is using the FG Gubellini spring that the Ayrton Superleggera runs on its FG Gubellini rear shock with a spacer to make up the difference in spring length. Even with a 450lb spring it is only running 5mm to 10mm perload so the rear shock is not trying to control a 1000lb spring on rebound and over heating the shock or having to try to compress a very heavy spring with massive leverage of the cheap Chinese swingarms. The modded link I am running was specified by FG Gubellini so it is giving the shock a much easier time. Even the high speed compression damping makes a difference as the shock has more actual movement so the damper actually runs through its stroke and allows the damping to do something. Where the normal 1000lb/1200lb shocks have very little motion through its stroke when riding so you are relying on the shim stack to react very quickly back and forth. Once we get moved into the new place, we need to sort out a ride on the bikes...
You’ve not mentioned DNM front forks, are they any good? Just changed the oil on my DNM fronts to 15W and they feel like they’re doing something right on both compression and rebound (in the garage mind, still not been on track yet with it myself!) 👍
@Pitbikesonic76 it does sound like that leg was getting foamy, after rewatching that section there's also weight... I've got volt v2.2 ( large blue rebound, v2.1 had the small rest triangle rebound ) I'm running 17.5w oil, at 175mm from top with spring in side uncompressed... I ride off road and there 770mm, would be really nice if you could get another play date with the dyno 💪 keep her pinned sonic

We have put a DNM rear shock on, and surprisingly, it worked well.

I filled mine with 10w40 engine oil 😂😂 feels great
A pair of Ohlins forks for an R1 probably cost £2000, and the DNMs we just bought were £200……so you get what you pay for I suppose😂
100%
Would be interesting to see how well a DNM rear shock dyno'd
Yes maybe another video for that
We dyno’d my rear shock when we did my so forks and very surprisingly it looked like a big bike shock on the data
@@RJLRacing96 DNM shocks have a decent looking stack of shims so not suprised they do a decent job.
Damn just got a bike with m-tec 😅 had volt before and seemed fine. Mtec much worse than volts ?
All same, bud just different sticker on side ... but with Chinese stuff, you might get a better set than others even though they are the same ....
Red Circles have the mtec/volt forks now rebranded as deepstate v2 forks
Just checked that out shame, don't make 660 size 😮💨
How did that bent fork not get stuck locked down position over the mountain at Cadwell 🙈🤣
Yeah, i don't understand how I am not dead 😅

DNM folks would be interesting as they are in the middle price range.
Unfortunately, they don't make them in my size 😕
You could rise fork oil level and see?...
Yeah, with the adjusters not doing a lot, that would be the next plain

Thank you buddy 😃
