Reply To: Sparking Issues / Rough Idle on GV125-S Aquila [SOLVED]
If its the Spark Plug Leads rubber sleeves , you may need to check the coils are not “arc-ing” (sparks leaking out of them or out of the plug) which i would be careful touching the cylinder heads as you will get shocked! (I found out the hard way many many times fixing customer bikes)
If the “inlet manifolds” which hold the injector bodies to the engine have split, i can’t tell, you will have to remove them and inspect their o-rings to show us if possible.
It looks like the electrical side and intake side where you’re looking at is now the issues , i don’t think the ISCV is the issue yet. (It wont work or fails early if its over-working to try maintain a stable idle where the bike is leaking air in other places or dropping sparks for a split second thats your caps and coils (hence every GV owner we know replaces the coils and caps as the 1st priority, then worry about making sure there is no air leaks before closing the bike back up)
Strip her down and investigate deeper on those intake pipes.
