  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

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
