'86 GSXR 750h firing on 2 cyliders, please help??
Thanks to anyone who takes the time to look through this.
I have an old 86 slabbie which I have run and maintained for donkeys years, its been sat a few months over the winter without running. Went to blow off the dust the other night but when I fired her up she only ran on cylinders 2 & 4???? I have put clean fresh fuel in her, replaced the spark plugs, done a fuel float and compression test, strip down and cleaned the carbs (pilot & main jet, float chambers etc) put her all back together and still only firing on 2 cylinders?? Any advice??
Thanks in advance,
