Hi at all of you who helped me very well in the last 2 years

once again i need your expertise and /or your experience to solve my problem !


I was ridding to the job when i stopped in this huged traffic .So my temp go up to 120 Celcius(100 celcius is th boiling point ),the bike was smoking and me too :evil:

so 25 min later I escape this traffic and finally cross the finish line of my parking job.

I go back home ,I tell the lady, i'm gonna pay the rent ,she said yeah , I said ho yeah and then she was heuuu..............(george thorogood)


go back to my story



so i go back home and did an oil change with mobil 1 syntech 10/40

i start the bike and (this is where my problem is ) i heard a tact tact tact tac tcatctact .


what I want to know is : what can cause a "tac tac " when an engine overheated is running .I let the engine running for 10 min and the sound was always there.





thanx for your help
 
Have you been running the 10/40 Syntech all along, or is this your first change to that oil? Just guessing with very little info so far, but sounds like valves clattering a tiny bit under a lower viscosity oil than the bike is accustomed to. It may not make any difference, but isn't the Syntech oil a Castrol brand and not Mobil 1?? I know that Mobil 1 is a synthetic oil, and is generally thinner than a standard petroleum base... I'm assuming the Syntech is also a synthetic. I'm just shooting in the dark here...
 
Did you change the filter?

If so did you put the filter in correctly? Did you have a spring on the cover that pushes against the filter? If you did is that filter sitting on your workbench?
 
no I was running a 10/40 regular motoroil ,that's why I change for superior oil.

Did you think my problem can be solve with a regular run once a day!
 
my filter was a suzuki oem parts ,yes i got my spring in the cover but now you put my in doubt if I installed correctly but I guess it's in good position.


By the way ,could you tell what the relation between a crrect installation and my trouble(i guess my valves)

If you can learn me something that I don't know in the mecanic I would like to know

thanx
 
Lets see if we can eliminate some possibilities... If you crank it up, and shift into gear (maybe ease the clutch lever out a bit), does the clatter seem to still be present, or does it maybe disapear or minimize? My thought is that the noise is possibly in the clutch basket-drivetrain, and shifting into gear might take up the slack and cause the noise to stop. If it doesn't, I'd probably go back to suspecting something in the valvetrain. Agoin, just shooting in the dark at this point.
 
I am having same problem after changing Oil. I didint change the filter though.

I changed to 20-50W because of hot climate here. & the old owner always use 20-50 instead of 10-40 as suggested by the bike GS450L.

then the sound goes away after few hundreds miles.

The sound always make me worry. now sometime the sound come back but just for few moment. if it come then I rev it high then the sound goes away.

hope its not big deal or need repair :D
 
Hard to say what a noise is if you don't hear it.

It might be your cam chain rattling. Just underneath your carbuerators on the back and in the middle of your cylinder block, is a small cylindrical device with a spring wrapped around it. That is your cam chain tensioner; sometimes it will lockup tight and not allow the spring to push the adjuster against the cam chain and allowing it to rattle.

WITH THE ENGINE COLD (unless you like blistered hands) reach in and see if you can turn the cylinder in either direction. It should have a quarter turn or so range. It should turn easily and then snap back into position. If it does not budge, get a tool around it and carefully turn it counter-clockwise just enough to break it loose. I also try get some penetrating (very thin) oil up around the mechanism as best I can.

If after this you still have the noise, you will have at least eliminated one thing and it cost you nothing.
