RB'd 220 CEK vs DEK Needle Differences

I have a RB modded 2003 220 (carb and head). Till now I have the CEK needle. I have a DEK in my desk here. Was wondering what difference would I get by switching to the DEK needle? What are your experiences with the CEK vs DEK? Is one preferred over the other according to riding style?

one has more of "hit" like the power gets on hard, fun for awhile but not woods friendly. I prefer the smooth delivery of the cek. Try it you'll see which one you like best
EDIT: not sure which one is which, but I know I have the smoother one in my carb might actually be the dek that's smoother...

I ran a CEK in my 200 all last season. Love the hit but for my skill level a bit difficult to control in the woods. I have some trouble finding a happy medium between wheel spin and looping out. Great in open areas like fields though. Have a DEK in my hand now but haven't had a chance to install/evaluate. Probably a month or two way.....I'm a fair weather rider and we're sitting under 30" of snow now.

The DEK is the smoother of the two needles and would probably be better for woods riding. I've heard others say that the CEK will really wear you out over a long day of riding. I guess it depends on your riding style.

Is this just differences in taper or something else? I've noticed the the CEK gives you a boost/hit some where between 1/3 and 1/2 of WOT.

I'm pretty sure the difference is in the taper of the needle...you may want to do a search b/c there a some very detailed posts on the differences in these two needles.

Would the DEK work in a non-modded carb?

The CEK and DEK work best with a # 7 slide. I know the stock 220 carb doesn't have a # 7...I think it's a #5. That being said, both the CEK and DEK work best in the RB modified carbs.

Right, and CEL/DEL for a non modded carb, and CGK for 89-94 carb.
Sound about right?

Before I found out about RB Designs, I ordered all of my jets and needles from Sudco.

CGK for 89-94 carb.
What's the difference between the CGK and a 1173 needle
Thanks!
