Cool!
might want to check cam chain and valves again.

Right after I replace the exhaust gaskets. Yeppers!Cool!

.... I cannot possibly express how ridiculous I feel for lifting the engine out of the frame by hand when there's such an... efficient way to get it doneView attachment 162100 View attachment 162101
Gotta break. More in a couple hours. Engine out!
Just think, all I wanted to do was change the oil!
Valves are .006 I and .015
Metric
Typo?
Indicates (at least to me) that it's a counterfeit. S K F makes (or did the last I knew) makes quality products. SFK not so much.
I replaced the exhaust gaskets and adjusted the valves again. It’s better, but still noisy.
Operating temp.
Like I said, do the cam chain adjust while it sits there idling. Then you can actually hear if it's making any difference. You might want to check the cam chain adjuster too and make sure the damper washer is there. It'll tick like that without it.
FWIW - the following are the leading manufacturers of bearings and seals globally (interestingly, a lot of these firms trade under three-letter company names):
There are others but those are most of the biggies. Each of these firms has a long history and almost all of them have had to battle cheap and inferior counterfeit products over the years. The best ways to spot a counterfeit are:
- SKF (Swedish)
- Schaeffler: (German) divisions include FAG (large industrial bearings), LuK (German - mainly automotive clutches and actuators), INA (smaller bearings and other automotive & industrial components)
- MPB (American - Miniature Precision Bearings)
- Torrington (American)
- NSK (Japanese)
- NTN (Japanese, I think)
- JTEKT (Japanese - I think)
- THK (Japanese)
- Timken (American)
- FAFNIR (originally German)
- Aisin-Seiki (Japanese)
While they look very simple, there is a lot that can go wrong with a bearing. In fact, making good bearings is not easy and it is pretty capitol-intensive, so anyone selling components like bearings and seals at really low prices likely is hiding something.
- silly spelling errors like the one pointed out above;
- a price that is simply too good to be true.
...like dimensional accuracy, correct surface finish, durable materials and overall quality for example.
An interesting side note is that Schaeffler and its various divisions is the firm where my students are working right now in Germany.
If this ends up being the case, the engine will go back in the corner and Ole Smoky will go back in the bike. I did pull the sump pate and replaced the screen. No tensioner rubber was visible, and I always look for it. I'm hopeful that 5Twins gave me the answer.That sounds an awful lot like Lucille did when the front timing chain guide lost its plastic shoe. Sorry Marty - but it really does. I would suggest pulling the sump plate off and checking for long black plastic slivers.
Here is the YouTube video that Jim helped me post of the noise:
If you check my thread entitled "Lucille pulls another one on me" - its all there.

..... manufacturers of bearings and seals ........
Yeah was scared to say the front guide thing.If this ends up being the case, the engine will go back in the corner and Ole Smoky will go back in the bike. I did pull the sump pate and replaced the screen. No tensioner rubber was visible, and I always look for it. I'm hopeful that 5Twins gave me the answer.
