it's a strange one. Thought I had a busted exup cable, but they are fine. The bike ( 04 fazer thou, well maintained, 37k) runs like a peach and pulls like that geordie feller Adam on "love island", but gets to 7500 rpm and it loses power and bogs, change up and it's back on song until it hits 7500 again..
I'm guessing it's got to be electrics or fuel, but it's just really odd because it's faultless until it hits those revs, even two up and loaded. It ain't been serviced since early last winter ( about 3000 miles back) as I picked up aa nekkid cb1300 at the start of summer and I've been useing that a lot, but I'll order a full service kit off eBay this week and get it done then try it see if it's any better. Anybody else ever had this? Ecu failing? Exup servo playing silly buggers? Damned if I know..😬😬😬
