Tenere dead after valve check.

[dmulk]

Time to request a credit/refund for the time you spent on this.

 

[MIMSEY]

Whew... Gotta like the easy ones.

Thankfully she broke down at home. Lesson to be had, don’t trust dealsrships to work on your bike. I was at their mercy because I didn’t feel confident enough to do a valve adjustment and I had a darned of a time finding a mechanic who was willing to do it. Next Tenere I’ll just skip it.

 

[robson]

so the punch line is, don't check valves on ST

Gotta love and appreciate all the endless info, help and advice that all the members of this forum possess and
are happily willing to share with one another.

(sigh) It's when people (motorcycle "mechanics") miss the simplest task that makes me wonder how they did the more complicated work on a bike. This is the very reason I do ALL of my own work on bikes...

Great to hear your up and running!

Not just bike fixers. Jeep had a bent axel. Dealership fixed it under warranty. While driving home....caliper bolts backed out....caliper fell on wheel....and ground it's way through the wheel. "Well, apparently he was sick on lug nut day" -- Ron White

Sorry, this is inaccurate, you are talking about a situation where you have flooded the combustion chambers with fuel, (probably because there was no spark or you have wet the plugs), and you say the compression is reduced? That is just wrong. This scenario will not reduce the compression.

You need to practice your quoting if you're going to respond.

Perhaps you don't understand the scenario? Oil helps seal rings to the bore. If you wash the oil off the cylinder walls with a solvent, (gasoline), you end up impacting the compression ratio. I.E. You lose ring seal. You can hear the engine spin faster than normal and with an odd sound. This, combined with the over rich condition makes starting the bike even more difficult. Google "fuel wash" or "cylinder wash down".

At this point, it's somewhat moot, since the problem was identified and solved some time ago. About a year ago, in fact.

Utter tosh and nonsense! If you wash the oil off the cylinder wall with a solvent, in this case petrol, then exactly how much compression do you think will be lost?

I'm not going to bother arguing about something I have personally experienced with the S10 and other vehicles. I did not break out the compression gauge at the time it occurred. You are free to disagree, but if you're going to waste your time, state your source or reference.

 

[Nikolajsen]

It does not happe often ;-)
But here I have to agree with EricV

I guess I could simply use your source of reference and say “Google it”, but I have built a few engines, both 2 stroke and 4 stroke in my time so I have practical experience. Maybe, just maybe once in a while you could exhibit a little humility and actually admit that you don’t know everything.

Oh yes, and remember, next time you have a chance, “break out the compression gauge” it’s very easy to use.

 

[EricV]

Run a lot of motors dry, do you?

I gave you links to read. No, I don't know everything. Neither do you.

I've also built a few motors. Assembly lube is your friend.

Feel free to call BS, but explain why you feel that way and maybe we can all learn something.

That's spooky!!

You’re funny, I don’t recall ever saying that I had “run a lot of motors dry” so I’m really not sure where you got that story from? Neither do I recall ever mentioning building a motor without using any lubricant either so where ever did you get that idea from?

 

[EricV]

You said you had practical experience. If you don't have practical experience with running a motor dry to confirm or deny a change in compression, why are you up in arms about my statements? And you have yet to offer any reference or explain why you believe otherwise.

As I said earlier, call BS all you want, but back up your opinion with something tangible, even if it's your opinion/belief of what you think is occurring.

My statements are based on my first hand experience with the Super Ten's classic Gen I hard start and my opinion on what is occurring.

Have you experienced the classic Gen I hard start? If not, why did you even bother to chime in?

 

[jmz]

One thing I always do when I start my bike is I do not quit pressing the starter button until the bike is running. Only time it hasn't started is when I didn't put one of the plugs on good enough that are on the bottom of the fuel tank.

Maybe a connector wasn't pushed fully home and it has vibrated off? First port of call is to lift the tank and check the connectors.

Hey Paul, awesome shout Mate. My bike died on the way home today. The short story is your post hit the freaking nail on the head. You’re a legend!

Old post I know, but when doing a compression check and receiving poor results, it’s common practice to repeat the compression test after squirting some motor oil into each cylinder. If compression results are improved, it indicates worn or sticking rings. If there’s no change, the diagnosis points to valve sealing as the problem.

So to answer the question, a little oil on the rings can make a measurable difference in compression. Note also that in a normal compression test inspection, there would not be solvent washed condition, if there were, the difference in compression by adding oil, would likely be even larger.
