Sounds like it could be more in your mind like it has consumed you a bit and is just stressing you out.
A carb balance is much better idea imo than just fitting other bits like air filters.
Did the garage geezer take it for a spin or anything, obviously he hasnt said anything alarming.
Your probably right about that.
Maybe my old Fazer was just really good and notice the little things more on this expecting it to be the same.
I did a carb tune on it about 2-3 weeks ago, improved it a bit.
The garage guy didn't say much else, just said about it running lean around mid range, then discussed dyno jetting and the cost.
He said if you don't mind putting up with it, it's ok and that the bike was in ok condition and nothing major wrong with it.
So maybe it's me just over thinking it and my daily commute doesn't really give me chance to open it up much so maybe it's just a bit clogged up?? Someone said give it some stick to help clear out the carbs? Not sure if that works?? Lol
Thanks for all the help though.
