After searching around for awhile I am surprised by the lack of info on remapping. Possibly a sticky like for jetting specs would be cool? Anyways...

Looking to address The flame out issue, some have suggested remapping could help the situation. Called my local dealer ans they said they can do it but would pretty much be guessing at settings. Does anyone have suggestions for proven maps or changes to make?

The bike is a 2014 crf450r stock motor with rekluse core exp clutch. I have no problems with the power delivery or the bike aside from the flame out /stalling.

Any help appreciated.
Thank.

Remapping is always beneficial if done by a competent shop who has done a lot of dyno and field testing. While there may be some extrapolation it certainly isn't "guessing". We offer this service and our maps are based off of dyno and field testing.

Just to verify I am using the right terminology. Would stalling at low Rpms say going over a log or a abruptly blurring on off throttle be considered flame out. Or is flame out under extreme acceleration?

Also found this claiming it is caused by camshaft and not mapping. https://m.youtube.com/watch?v=XHaPdixbZgU Not sure though because even all CRFs to my knowledge have had decomp cams and this issue only seems to be with FI models.

What kind of turn around do you have on remapping?

Most often the same day if yours is delivered in the morning. If not the next day.

In your professional opinion and experience, will your remapping solve my described issue?

There can be other causes for this condition as well so I can't say with certainty that it will solve this issue. However, the stock mapping is horrible so a remap is needed regardless and it will at the very least eliminate the mapping the source of the problem.

Took your advice awhile back and had you re program my ecm. I'm still having stall issues with my rekluse. My current recommendation from ten is the 'hard' engagement springs (6 blue).

In doing this you have to increase the idle speed to match the engagement. The rekluse technician still things the issue is caused from flame out and states that if I can get the isle up the bike will be out of the flame out zone at low speed.

So now the bike at a stand still has a slight pressure trying to move forward but is by creeping. But once I get going it appears while in motion the engine speed is increase and the bike is propelling Italy forward at about 5 mph and will continue to do so until I apply the brakes. At that time at a stand still the bike return to idle without moving forward.

Would this increase in rpms propelling the bike be do to mapping or is this a sign the high engagement blue springs are not going to work?
