  • 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 The previous version was outdated and no longer supported.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!

Darn Stallin' (JD Settings?)

Most of my riding has thus far been in the twisty stuff, not much stop/start traffic. Now I've been working on the bike, and had the chance to ride to work I've noticed while pulling away from the lights or blipping the throttle like a tool waiting for the lights to change, that my 511 likes to stall pretty easily. The bike runs without issue everywhere else in the rev range, it's just the low speed stalling that's annoying me (and the people behind!).

Bike has Full Akro EVO Ti, race map 2 plug and JD tuner, not sure on settings on the JD as it was installed then hidden under the seat soon after.

I'm lead to believe the green settings on the JD are where I should be twiddling?

EDIT: I will check the settings on the JD tuner in the morning, when neighbours aren't as opposed to an uncorked Akro running.

I'm tossing up whether to get it tuned on a dyno to get a settings for with and without the baffle in the exhaust as a few tracks near here have noise restrictions. Another option is possibly the bazzaz/dyno tune with map switch and sell the JD tuner. The only thing I dislike about this bike is the stalling :(
 
First thing to do is write down the settings you have now. Second, don't be in a hurry to make changes. Ride the bike lile you always would. Let it get up to temp'. When making adjustments, be conservative. Keep the adjustments small.

With my 510, I found that the "blat ka-thith" flame-out was caused by too much fuel just off idle at slow RPM. Try leaning the idle a step or two and see if it improves. If not, or it gets worse, return to the original setting and decrease the accelerator pump function one or two clicks. Also asses if it's better or worse. If it seems worse in both cases, try going in the other direction.
 
My 449 runs the leanest setting on green just one. Ive a full fmf, deristricted air box and my yellow is on 4.5 and red is 5. If the green setting is to rich the bike may not run good. i went from 4 on green to 1 and this appears right for my bike
 
Hey Spud, what did you do to the airbox to derestrict it ?
The stalling thing can be really annoying. Mine seems like it's not as bad as it used to be but
it has this uncanny ability to know the one exact moment that I need it to go, it stalls. I've actually
adapted my riding style in certain situations to prevent this so it's all good. Love my 511.
 
The air box has two 70mm by 10mm holes cut into the cover between the retaining clips and locating points either side on the lid cover. This makes the bike rev quicker, a lot quicker and holds the power top end.
 
Caiman,

Hey mate Ive got a 2011 511 and Im running a JD tuner aswell, after much fiddling and stuffing around with it I didnt get any great results until I started playing with the big brass screw on the EFI as recommended on here. To the best of my memory I turned it out 1 and a half turns and its running perfectly now and i couldnt be more happier with it. The most important thing to do is write all your original settings before you start messing with it too much.
 
I just read this thread, and although Bankso had the riight idea, my bike was the opposite. I had the EXACT same issues, now while i'm sure the JD settings can be altered, after I did the following, the fastest whip of my throttle makes the bike sound like a gun shot! No issues whatsoever:

Exhaust:

FMF full open

Airbox: stock

JD settings:
G -4
Y - 5
R - 5
G/B - 3
Y/B - 4
R/B - 5

brass screw...exactly 2.75 turns out from 0.

FYI..when I tried 1.5 out, the bike would NOT run...

I hope you get the same effect as I did..Ive been searching for this "holy grail" on my bke for months.

Good luck! Please remember...I only use my bike for street use...so "long" idles at red lights, etc..which seems to be your issue too.

Well, I was "wrong"...still not 100% there, but almost. I did have it die once on my on my way to work, but it's still a lot better than before. Will continue to tinker.
 
Well I just went out and got the settings off my JD turner and they maybe a good starting point for you, as I in Australia aswell.

Bike has stock air box
Akro pipe not full system
Is in Race map II

Turner settings are as follows:
Green 2/3
Yellow 4
Red 5/6
Green/Blue 3/4
Yellow/Blue 4
Red/Blue 5/6

with the brass screw on Throttle body screwed 1 3/4 turns out and reset the TPS aswell.

Hope this helps
