SV650s K6 with C25 error

[Tizpete]

Hello all, first timer.
I've just fitted the engine back in to my bike as its been out over a year. Engine runs lovely and smooth BUT i have C25 error when in dealer mode . FI light is on. I'm guessing I need to check for a strong spark. Any thing else i can check ?

Hi and welcome, check the connections at the rear cylinder ignition coil, check the plug cap is good, and maybe fit new spark plugs if you haven't already.
