I've done a few searches using similar words but haven't really found anything exactly like my issue. The bike starts perfectly. It idles perfectly. It does not cut out at slow speed or coming to a stop. The issue appears when moving, specifically at full throttle in 5th and 6th gear as it seems the bike struggles to get through a 5,000rpm flat spot. At full throttle in 5th and 6th (where it is most noticeable but happens in all gears) the bike suffers power loss and backfires as if fuel starved. If you keep full throttle on it will eventually work it's way through it but it's not pleasant. If I roll back off the throttle to say 50% then it runs through it no problem. This hesitation also happens at 3000rpm (not at full throttle) but it seems to rev trough this quicker yet it is still not pleasant and in the wet the unpredictable nature of this fault does not inspire confidence. The issue can be intermittent but is mostly always there. From what I have been reading up on the famous oul internet some people have just replaced spark plugs and this has resolved the issue so that is my next step. I had not replaced them yet as they were recently changed on the service history. I am also concerned it may be coils or fuel pump. The fuel pump was replaced under warranty a few years ago. The coils seem original. Has anyone had this issue? I have had the bike since Febuary service so is as follows. New oil, Oil filter, Abs flush, Valve clearance, Gearbox oil, Final drive oil, Air filter. Tips sensor reset. Some other small bits. I have lubed all electric connections. Replaced headers with decat headers. New end can. None of the above has in anyway resolved this issue. It appears it's worse after warming up hence why I'm leaning towards coils or plugs at present. Yesterday the first 10mins of a spin the bike was perfect then the issue raised its head. I stopped after 30mins. Restarted my journey and with the warm engine the issue was evident straight away. I can kind of ride around it but life's to short I want it sorted. Love the bike but this is a pain in the ass of an issue. Thanks to all you wiser men than me in advance. Skapegoat Ireland.
