Hot Start Cure 2010's 390 (aus)

Just went to a dealer,to get map reflashed ,which is now done, reason for flash,he claimed the standard maps have been modified to resolve the Hot-start problem or should i say the hot-start,not-start-problem.

With my bike when hot, it was definately on the button once,for 0.5 sec, to get a revolution of the pump,(a dale tip) then on the starter again and it would fire only 70% of the time .Without that routine hot-starting was a 4-5 button hit operation,with throttle rolling.

So don't know if the modified map is around the world yet, or if its bogus, but it might be worth checking......if youve got that problem. If you got the user tool you can modiify yourself.

Will post how cured the prob is when I get the chance to do more than load it on and off the truck.

total fix,got the hot sart prob., get the flash !

I think if there is any confusion as to the mapping issues, a post should be raised in Dealer + Distributer Discussion and see what response comes through. There seems to be a learn-as-you-go approach to EFI issues by all including those with the OEM knowledge. My advice is persevere.
As posted I went to local dealer in CHCH (D+E ph # is under dealers on the official site CHCH NZ, if you want your dealer to ring ) in discussion over Akrapovic reflash ,which isn’t needed, he mentioned that the standard maps had had a correction that resolved the hot start problem. This is a standard reflash, with the standard maps.Just the latest version of them.
Hense the reflash . Is it out there? hell yes !! Does it work….one finger nail on the starter when the bikes a cooker….starts every time…when do you need it….stalled half way up steep hill section….that prob combined with the stiff clutch when new, is one that’ll have you dogging the bike to the bottom.
I would have thought the maps would have been modified across all models as it was a generic issue.
Beryls and Davo are you using injector cleaner ? I have researched a great injector cleaner and fuel conditioner…and guess what its Aussie!!! Well the distributer is any way, will post the brand name as it slips me right now. 15 mls added to the 8L tank everytime you fill, keep injectors clean. I dropped out spark plug to see if it was doing the job and she was clean as a whistle. Also fitted 70 degree pump filter (new filter mod) modification on the weekend. Once you do that, you realize how much fuel can go unfiltered, over the top of OEM part (filter)into the pump. Highly recommend it and the in tank filter, both from Dale, as I think the trouble free future of this bike is in keeping your EFI system as clean from contaminants and debris as possible. As part of instillation of filter, filtered fuel, and cleaned tank, there was quite a collection of foreign bodies collected from bottom of tank.

for those that are inclined to a bit of a flush once in a while...

good investment the filters!

Don't know if you guys have installed the filter yet, its a tight fit, there is a little spring steel lock washer that holds the OEM plastic part onto the bottom (before the filter) of the fuel pump,its stubborn to remove, but it can go back on and lock the new filter back on. Also pulling the pump out of the tank, the line in the tank can stick, and theres a bit to damage by pulling hard .You can free up the coiled fuel line by releasing the top part of the line 3 screws on the filter catch.

bergls,Dale had the same problem with a poor hotstart on his 570 dont know how hes got on.....whether he solved it. Maybe he'll post.
