Its probably just normal engine noises. Since your bike is carbed its not the normal ticking that comes from FI. If you thinks its a problem take it back to the dealsership.

I've been hearing it's normal... it's nothing too loud, just a noise I'm not used to I guess, coming from an I-6 BMW car haha... I'll see if/how it changes and go from there I guess

Just make sure you have enough oil. How many miles are on the bike? Is it brand new?

Yup, delivered yesterday... I checked gas, oil, coolant, and a few other things that I know something about haha... everything seems in good condition so I'm sure it's normal.

OT: How normal is it for a bike to overflow the engine with fuel when it's turned off, so that when you turn it back on later, you have to give it a little throttle in order to turn it on? I read that in the manual and I had that experience with my car one time before, but just wondering if it happens more often on bikes ?

Which I-6 did you drive?? I had an M52 (98 328i) and never heard a single ticking noise... always used either Mobil 1 0w-40 in winter and pentosynth 5w-40 in warmer months

I used to have a 88 325i it was a nice car, but compared to the japanese four cylinders I have owned before and since it sounded odd to me. I was driving my brother in laws truck with an inline six and it made similar ticking noises. Bmws are quirky strange clutch action and wierd feel that I never got used to nothing aqainst the cars because they are good cars, but I prefer honda or toyota for overall feel....

shouldnt happen. well, under ideal tuning it shouldnt. if you have a float needle that is stuck open, or something to that effect, it can happen though.

So every time you start the bike it should simply start without any throttle? Choke if necessary?

IDK I pretty much always have to give it a little throttle when I start me 00 zx6r. Pretty much the same bike as yours except the front fairing stay bracket. And that ticking noise is prolly normal as long as its a ticking not a clanking or tapping.

I have to do that as well... my bike won't start without a little throttle, even when the choke is on, and even if it's warmed up... should I just raise the throttle (idle) a bit or is there something else?? It's nothing big but it seems like the engine is flooding a bit every time I turn the bike off... so far in 5 days of ownership, it only turned on maybe 30-40% of the time as it should (with no throttle at all)... any input on this...

I was planning on just raising the idle RPM a bit (manual says 1250-1350 and now it seems like it's at ~1000-1050... and if that doesn't work take it in to the dealer... it's brand new so I'm not really worried haha, just annoyed

Raising the idle doesn't help i've already tried it. I just assumed it was normal. If its under warranty hell yeah I would take it up there and let them do it.

Mine has always just had a slight ticking noise, I think its the cam chain. But iv never had any problems, Iv taken the valve cover off and checked the tension and it was ok, So my guess is its just a mechanical sound it makes. Mine runs like a champ.
