Hippy

When I changed my stator, I didn't use threadlock, just torqued them up, threadlocked now but I think my stator is dead again, so possibly did more damage than I thought.

The stator is not attached to the flywheel, it's attached to the stator casing, the rotor is attached to the end of the crank shaft.
The magnets in the rotor will pull the stator all over the place if it's loose, they're very strong magnets.

Couldn't tell by the charging voltage, but the clatter could be felt through the stator cover easily.

i had same thing happen to me on my last stator change. started hearing a rattle type noise. so got back to home immediately, pulled it off and sure enough, bolts had backed out. fixed that, stator was fine and i was back on the road

Another video link

There is another video, a better quality one than the first one. Ticking noise comes from left side of the engine actually, and I can hear it well while riding. It gets louder when the engine has warmed up and might be louder now than it was some time ago.
Haven't had much extra time lately, so haven't checked valve clearances or anything yet..

Stator is on the left side of the engine also?

I have also noticed that engine temperature rises quite quickly to over 100 celsius and fan kicks in, if running slowly or have to stop for red lights too often, but I think that is normal for tt600? When running over 60km/h temp goes back to about 85.

The temperatures are normal, nothing to worry about! But if you think its getting worse stop driving it! If it is the stator, like a few people seem to think it is, when it finally comes loose you will certainly increase your expenses.... So either take the time to start some diagnostics, or stop riding!

PS i havent watched your new video yet, I will when I get home and see if I can provide any other input.

Checked valve clearances today:
exhaust (left to right):
pair1: 0.20-0.25 / 0.20-0.25
pair2: 0.15-0.20 / 0.20-0.25
pair3: 0.20-0.25 / 0.15-0.20
pair4: 0.25-0.30 / 0.20-0.25

inlet (left to right):
pair1: 0.15-0.20 / 0.15-0.20
pair2: 0.10-0.15 / 0.15-0.20
pair3: 0.15-0.20 / 0.15-0.20
pair4: 0.15-0.20 / 0.15-0.20

(my gauge was with 0.05 mm steps, so don't have exact number)

so they seem to be quite ok.. (Should be: inlet = 0.15 - 0.25 mm, and exhaust 0.20 - 0.30 mm)

I don't think that the stator/alternator causes any rattle. Can't feel it coming from under the stator cover (more like from top end), but if I check it, do I need to drain oil out of the bike before opening the cover? (= is stator in oil?)

Kwhite

does have some oil in it. not a ton though

Did you check these clearances on a bone cold engine? If you didnt let the bike sit for like 24hrs before checking clearances, those numbers mean nothing.

Assuming you did, and the noise is NOT the injectors. I wouldnt ride the bike until you either figured out what the problem is, or got an experts opinion on if the noise is normal or not.

I am experiencing very similar sounds....did you determine what was causing your noise?

Not sure yet. It is winter now (cold and snow everywhere here in Finland), so the bike is now in garage waiting for summer time
I have driven 2000-3000 km with the bike since my posts here, and at least it still works ok, but the ticky sound is there.
Bike was also quickly checked in a local motorcycle service place during last summer. They didn't do much, just tuned my ecu map a little plus some other minor things and said these are noisy.

I think before next driving season, I will adjust all valves to same spec, change spark plugs (noticed that one of them has been over-tightened at some point by previous owner.. threads gone roundish) and change my cooling system fluids.
