Well i worked on the brothers 900 all day this is what i found and it is fixed.
Found bad ground wire from tps to pcm raplaced wire. No more back fire still runs like crap reset tps no change after checking every wire on sled with omh meter every thing test ok. put in line spark tester on both wires found pto side coil would not fire all the time swaped coils off mine runs great put 60 miles on it. Thank god was just about fire time but its good runs like a champ.
So to recap bad ground wire tps to pcm and bad coil.
Hope this helps some one else down the road
