Aggresive acceleration.

Finally got my TE511 on the road... but throttle feels very aggresive. Like it snatches the cable early. Seems to be an initial delay... then comes on. This creates like a jerking effect... and i cant ride the throttle smoothly.

Whats peoples thoughts. Can i adjust anything?

Thanks.

I found my old 449 was like that and it was also idling too high and was not adjustable below 2200 rpms. It also de-accelerated way too slow, like a 2 banger rather than a 4 stroke.
Maybe try a G2 throttle tamer. Its cam profile is softer initially and gives more control in the tight stuff. I have one on my Beta 480, great product.

Try adjusting the big brass screw. Count how many turns til all the way in before you start you should be somewhere between 3-5 turns out from all the way closed. You can adjust accordingly from there (more or less)

my son's 511 does (did) the same thing. but it now runs strong up high, but pretty shitty down low. I need to adjust the JD maybe, after the ZipTy ECU mod was done [2 thumbs up]. It has no more "tight" throttle, but instead a lot of rpm surging which feels different. The FBW butterfly is still installed.

But you might consider removing the FBW butterfly and high-idle cam thingy and see what that does for you. look for the CH threads.

Sounds like an odd thing.
The power is usually very smooth, even with the second butterfly removed. My TE449 is very easy to ride around on small throttle openings.
I have no butterfly, Map 3 (Akro Map) loaded in the ecu and my primary TPS reading set to 0.75v at idle.

There is a common slight, very light throttle hesitation noticeable only in road riding through a town or the like.
All our normal riding is proper Enduro type stuff in the bush, so it doesn't concern me.

I would suggest the throttle stop is adjusted too low . Vacuum pulls the butterfly stuck shut against the housing then you have to pull it hard to break it free and it goes jerky. Happens on cars too . Adjust the throttle stop fractionally higher . Then wind idle speed down with bypass screw

The ecu will self adjust idle speed if the idle arm is still in place.
