Are any of you doing that? On the synch issue, I just gave away my trusting mercury sticks (banned a loooooong time ago) thinking those days were over. Oh well. The reality is the better the synch, the less engine vibration, so might not be a bad idea to check it at least once. But on most bikes, it's a royal PITA to do, especially if the fuel tank needs to be removed, as you need a secondary 50-psi fuel source to run the bike. How hard is to do that job on this bike? Anybody done it before?
And in the age of 100K-mile spark plugs, why on earth do they have to be replaced every 7.5K miles? Does anybody do that? I imagine it's not an easy job either, due to lots of crap in the way. At least airbox removal, right? Just like if you were to check the valves. I'd replace them at that time (15K), not 7.5, but want to hear your opinion. I was expecting A LOT less maintenance than on a BMW, but at least based on the owner's manual, that's not the case. What I have ZERO doubt is it'll be more reliable .
There is no need to remove the fuel tank on the C14 for any engine work...it is of zero benefit...there is nothing under it except frame. Even if you do have to get under it for anything...you only have to tilt the tank up...not remove it. The only time you would ever remove the fuel tank is if you had to drain the fuel or access the fuel pump/pickup screen.
There is no airbox to remove on the C14...it is integrated with the frame.
Syncd the TB once at 60k, couldn't tell any difference. Waste of money.
It is a waste of money. I've done more of them than I can count, and I have never found the throttle bodies on any EFI bike to out of sync enough that they made any difference. Sure, you can adjust them...but you're in the area of splitting hairs, so any change you do make won't usually be noticeable.
I think a lot of things...like a TB sync, and it's importance, gets carried over from carbed bikes. On carbed bikes, a carb sync can make a big difference. On a late model EFI bike...not so much.
