Thanks in advance.
There is a dealer here is Canada dual sport plus, I bought one a couple of weeks ago. I'm not sure if they ship to the USA if not you can have it shipped to my place and I can ship it or could drop it in the mail on the USA side in a few weeks when I an there. If that helps.

I am not a good rider, especially when it comes to steep narrow tracks, so a fww could be fine for me (maybe).
On the other hand I have sometimes problem at really steep ascends that have to be climbed with high speed.
If i had such a heavy fww on my ec 300 06, would I have to be earlier with the throttle or open it more (maybe both?

The FWW just adds inertia to the engine. It won't build revs as quickly, so will be smoother (less likely to break traction, or get away from you), and the same in reverse. Will want to carry and be less prone to stalling.

It's all personal preference. A 300 should have no issues with a bit of extra weight off the flywheel, if that is what you're looking for. Others prefer snappier more responsive power delivery.

There are always other ways to tame things with throttle tube/cam systems, jetting, gearing, tyre size/mass.

The whole lot works as a system, so really you want to have the suspension matched to your ability and terrain, and balanced front to rear. The engine characteristics to suit your desires. Then focus on your skills. Clutch, throttle, body position, and technique.

All easier said than done. But your issues aren't anything that we all don't face. What one person considers unrideable/impossible another may find a challenge, and another may simply make it look effortless. It's all to do with skill and technique and the more time you put into practicing and improving the better you will be equipped to deal with them. FWW or not.

Excellent post.
Well said.

To address your question directly:
With a heavy flywheel weight, you may have to be earlier on your throttle to get the engine up to the rpm you want, since the fww makes the engine gain rpms a bit slower. (Maybe just a fraction of a second sooner, but sometimes that fraction of a second does make a difference.)

As Jokobi said, the flywheel weight will make the engine more resistant to stalling at the expense of a bit of "snap" to the power delivery.
My suggestion is to add a fww if you are having a problem with stalling the engine or a problem keeping the power under control. Also, in your calculations, you can also choose from a variety of weights.

An example: With my 2006 DE300, I had plenty of power and could control it, but my fuel usage was too high. I wanted more mileage from a tank of fuel.
I contacted RB Designs and had them reshape my cylinder head and adjust the squish band by shaving it a bit.
When I reinstalled the head after modification, my mileage greatly improved.
However, the engine gained enough extra snap in it's power delivery that I was having trouble keeping the rear wheel from breaking loose in rocky off-camber corners. (The rear wheel caught up with the front wheel twice on the first test ride. )
I then installed a Checkpoint Machine 10oz flywheel weight and my testing showed that I now still had "snap" in my power delivery but not more than I could use or control. (I just looked at their website an it seems that now they only offer the 12oz weight.)
Matt Stavish, who owns and operates Checkpoint Off-Road, was a spoonsered rider for the GasGas Factory's National Enduro and Hare Scrambles team in the early 2000s. Here is that catalog page which shows the fww weight.
http://checkpointoff-road.com/store.html

I"ve played with all the different size flywheel weights available, and I personally don't like the extremely heavy fww. (23oz) They take too much of the "play power" out of the power delivery. And, sometime that extra snap will get my front wheel up over an obstacle a quickly as I need it to.
A 10oz weight is usually my recommendation for someone who wants to race, but have more control over the engine.

You will just need to decide what you need, in relation to what you have now, and do what's best for you.

I hope that this helped you in your deliberations.

Good Riding!
Jim

Thx Jakobi and Jim, you confirm what I already was afraid of, the fww won't make me a better rider

Less stalling sounds good to me as kickstarting at steep hills isnt my favorite...
I'll try to find a 12oz fww here in europe.

My 2007 loved the extra weight, I love it in the muddy conditions we often get here. But the head mod makes the bike Trials like at low revs. Great for tricky stuff. Do that.
