I have a gsx RFI .
My first run this year whent bad i started the engine and sailed out the habour
but the engine would only fire the front cylinder. And max rpm was 2400.
The 12v alarm startet to so maybe a good idea to change battery.
Tjec list so far:
12bar compression on both cyl
spark on both sparkplugs
tjecked the rear RAV valve but it was very clean!
What could it be?
