Steering Column Flex: would a taller SCS help at all?

If you'd like to reiterate yourself, try rewording your post or being more descriptive with your explanation. Tell me why you don't agree with my new post (that's better explained) since I wasn't very explicative with my own thoughts the first time. Please don't ask my age, it has nothing to do with the question. You realize I don't disagree with either of you, right? I just want to gain more information IF possible while sharing my own thoughts and understanding in hopes of gaining even more of an understanding. Interpret it as you will.
I'm not trying to argue I think your one of the most legit OGs. Ok so I run 27high with scs and have a tilt scs tilt nimbus and tsi hammerhead. It wobbles but not like bad when I go over a street crack like the ones where the cement has separated and I use no hands the bars wobble probably 4 full times back and forth before it stops. Hope this helps!

you'd think a clamp that's even shorter than 3 inches wouldn't be clamping to enough of the fork and bars because it's only holding on to the very ends, and being that they were the very ends, (like holding the pencil when trying to bend it) would cause more flex as less material is anchored down - like wide bars without gussets vs wide bars with (even small) gussets on the inner end.

(Bold to clarify this is the biggest factor in what I'm basing the thread off of)

As I said before the ONLY benefit of a full size SCS will be that you get .5" of extra contact between your clamp and your bars. It will not have any more contact with your fork because most scooter forks only go about 1.3"-1.5" above the headset, so there really isn't a need for a 4" SCS. Regardless of whether you have a 3" or 4" SCS you will get flex with 27" bars. It is a scientific fact, there is no point in arguing. Some people may not notice it, and some other part on your scooter may actually be the cause of the flex(ie. Thresholds decks have a lot of flex. It could also be your headset bearings are getting pitted, so even when it is tight there will be flex in the headset).

After getting everything in line and compressed properly, I find that the steering column "flexes." It doesn't wobble back and forth, it doesn't shift backward/forward when you push and pull on it, but the bars "bend" with pressure, always returning back . It's not a loose feeling at all, the whole column is flexing like a skyscraper in the wind. Would a taller clamp clamping a greater portion of the ends of the fork and bars help correct this to any degree?

(this post has been edited from my original inquiry about oversized bars correcting the flex)

your bars flex, thats normal for something with leverage type stress plus the size you have. 1/2 inch compared to 27.5 inches or fraction 1/55 isnt much but yes its something and will make a tiny difference but with a cost of problems being moved or expressed differently not eliminated entirely.

you say you hate alu forks? they are made for a good reason although you may know they have risks also for yourself. id expect you have steel ones, that brings up the problem with a bigger scs. its gonna make your bars feel more stiff then they are at the fork/scs/bar connection and thats 1/2 the bad news ironically.

putting on a 4 inch scs will make the fork more prone to being the weakest point and wreck havok on front balance which i dunno why youd want that but also as you want to know, the 4" scs will help with the feeling of the bars that you are asking for and if ridden right would be a bulletproof combo for sometime, not forever. i can make my scoot last a day or a year, up to me.

i already know thats the opposite of what would help to make riding easier, more weight and more to the point off balance. your scooter would have to be a tank in my eyes. i rode for mgp, i will never ride a scooter over 3 kg again but if thats what YOU want then thats the estimated plus practical experience expected outcome.

I think someone said earlier that a larger diameter downtube won't change the flex, which isn't true.
Don't ride smaller bars, just ride oversized bars. You wouldn't believe the difference.

How so I get the same amount of flex with my Heps then I do with my tyler bonner sig bars.

I swapped out my stock tilt compression washer for a convex bike cap.

Convex bike caps helps significantly, the generic washer provided with tilt's 60 dollar SCS is garbage.
I also think using a slimmed down SCS (Tilt LT) makes it trickier to tighten evenly the entire way up, because the top and bottom of the scs are different diameters.
