what is the stcok flywheel wight in 2011 EC250E?

[a c t i v e X]

Hey

I'm checking the option to add weight to get more traction and less anxious temperament on technical rides without hurt too much "the monkey" ...
does someone knows the original weight? is it have weight at all or pure flywheel?
i've read of 8/10/14/22 OZ weights, where are those available from?
are they just bolt on or requires drilling?
any help on this is appreciated

You should have the large flywheel 2K-3 ignition. The weights are for the smaller 2K-2. They spin on in place of the flywheel nut. I suggest you try a G2 ergo throttle with the #200 or #400 cam. It will give you much better throttle control from idle to half throttle.

what gmp said plus how is your jetting. I ride pretty technical stuff. Once I got the jetting dialed it was easier to ride. I think I'm running the g2 200 cam too.

I don't like a lot of flywheel. I ride some very technical stuff and get along fine with a 2K-2, 10 to 14 oz weight, and a G2 with #200 cam. The 2K-3 has almost TWICE the inertia of this setup. Like skid said, proper jetting as well as a G2 and your good.

2k-2 with 9oz on a 300 is what i run. i can't deal with the 2k-3.

if you already have the 2k-3 no fww available, as others have stated the 2k-3 is already heavier than any fww you could run.- jetting and throttle tube is everything on that setup. if your gearing is obnoxious that could be an issue also...

problem is not in the response only

compared to my previous KTM 2T, i feel the engine is lighter and more "jumpy". this goes both ways when the spin may be faster for the condition which end with skidding on the rocks and worst- when hitting obstacles it goes down faster and lose the momentum. this end with stalling much faster that in the KTM.

beside of that the bike is awesome, great engine response and top end, amazing handling and confidence.

so bottom line is - no more weight available, yep?
I've ordered NEDJ needle to get smoother response, but i don't believe it will keep the flywheel rolling when hitting steps

 

[stainlesscycle]

most of the ktm 2t's run the 2k2 which is significantly lighter...
your jetting could have lots to do with it. it is a 2k-3 on all newer gg 250' s right?

 

[GMP]

Yes they have 2K-3s.

activeX,

My 250 has a bit less torque and a lot less flywheel, but its jetted perfect and never stalls. I have no problems riding all kinds of gnarly rocks, ledges, roots, off camber rock slab hills, etc. Its jetting and throttle control. Once you get the bike dialed in, and try the G2, you may want the ligher 2K-2 also. The big flywheel can mask other issues.

thanks

I'll get the jetting done, hopefully it will mallow things.
don't want to change throttle since i have a mixed riding styles, many are technical, but also some dunes, mountain and local MX tracks.
afraid it will be too 'sponge' with the gas response.
no one i know installed such G2 to try...

 

[GMP]

The G2 is an excellent product. If your unfamiliar, its a two piece alloy throttle tube with different cam profiles you can snap on/off to interchange. It allows adding progression to the cable pull (throttle slide opening) relative to twist, but ONLY in the first half of the twist. This allows really nice control of off idle to mid throttle in technical sections, but a hard twist is always WFO, with no unwanted lag from an overly heavy flywheel. JMO, but a lot of guys here also really like them. I even ran one on my Ducati Hypermotard to better control the strong off idle response and make it more civilized for commuting, and it would still wheelie at will.

After reading all posts I find it funny no one has mention using the clutch if you feel the bike is about to stall. Maybe it's a old habit from riding trials but I always have one or two fingers covering the clutch...very seldom will my bike stall. Just a thought...(not to take away that proper jetting is important)

 

[GMP]

Of course, but I thought that might be a bit insulting, like telling him to start it with the choke in the AM.

 

[gassi]

so bottom line is - no more weight available, yep?

Yes there is: http://2tracing.it/ricambi-gas-gas/motore/massa-volanica-aggiuntiva-ec-250-300/

Also you can use 2006 and older models crankshaft counter balancer (ME250112017) which have more weight.

Hahah yeah good call GMP

If the jetting is fat off the bottom the bikes have a tendancy to load up and stall out easily. They also give you that perceived 'hit' from when you go from soft rich power onto the needle and into some leaner power. All of this can happen right off idle (0-1/4 throttle) and IMO makes the bike very difficult to control when things get technical.

Clutch control will help, but if the bike is that rich that it won't idle at least for a few seconds it becomes extreme clutch and throttle control which while is the basics and we can all do while riding around the yard, becomes somewhat more difficult after smashing a few rock ledges and having the arms bein to pump up.

I don't think you're looking for more FWW. If you're still on the original needle jet you'll notice a drastic change in power delivery once you have a tinker with some others.

thanks

sure i'm using the clutch. i also keep in mind that gear is left leg, 1st gear down, than up...

I will wait for the NEDJ to arrive and set it in before digging into engine parts.
