I have a new to me WR250R with an EJK programmer and it is not dialed-in. Here is what is on the bike:
1. All emissions deleted
2. FMF Q4 Hex and powerbomb header
3. Small hole in the side of the air box
I am at sea level and it is stumbling when I give it gas in at low rpms. If I give it too much gas when lugging, it stumbles.
I have to believe someone else has this same setup at sea level. If so, I'd appreciate you posting your settings for each mode on the EJK.
This is my second WRR. On the first, I did all the mods and used a FMF programmer. I was able to get it dialed-in so the bike ran clean and crisp all the way to the rev limiter.
Thanks,
Bill
