Back round on the bike
2012 wr 450
Approx 5500kms
Oil changes ever few rides/hours
All free mods/ecu remapped with the fmf map
Gytr/fmf power core 4 slip on
Fmf snap

*********never had a valve adjustment as of yet. Bike is going in Monday to have the valves done and a new 07 yfz intake cam installed

Ok this is my issue this only started to happen like 3 days ago . when I first start my bike cold the bike will run for like 5-8 seconds and stall so I re start it and jump on all seams ok so I put it into gear and hold it in first with he clutch pulled in. If I just sit there for a while the bike stalls again.
Like I said I been riding this bike a crap load and now since 3 days ago this happen every time I start the bike up cold. Ppl might say its because its cold but l think it's more to it than that because I have has this thing out I the winter heavy old rain ECt and never had a problem and my friends bike which is the carbon copy of mine of the same year and make with approximate 200-300 more Kms than mine and his do not do it

Any suggestions?

Does the bike stall when hot or only when cold?

Check your valve clearance, I just had an intake valve with zero clearance. Now that it's adjusted, the bike starts better than it did new.
