Anyone running a 1250 kit with 10.5:1 pistons that has a viable fuel/timing map for this setup. I am finishing my 04 xb12r rebuild with a 1250 kit from hammer and a Jardine
Thanks j.ekins
I know one guy running it with just an EBR ecm and free flowing exhaust no tune, and he says that it runs smother than stock. I would still recommend a tune, but I guess its possible, and yes this is on the 1250 kit!
