10w40 to light?

Postby flyfisher1011 » Mon Jun 27, 2011 7:17 am



I bought this 1986 gl1200 a and serviced the bike after it had set for 3yrs. I live in texas the heat is 95 plus. I used 10w40 gastol4t. Now I have a knocking as in a lifter gone flat sound. My question is, would this to light of weight of oil causing the lash adjusters to go flat? And would 20w50 be needed to make them pump back up?

You might want to add some seafoam oil additive to oil and run it some to see if there is some gunk built up in the lifter that will free up. When you change after running it some 20/50 probably would not be a bad choice.

Thanks I'll give that a shot. This is my first wing and am learning more as I work no it. Working the bugs out of it. Runs good and will run better shortly with the good lords help and maybe more insite from those of you who have been dealing with them for a while.

It would probably be a good idea to run some Seafoam in the fuel tank also. I ran it in my first couple of tanks of fuel when I brought it out of winter storage. I also run it in about every third tank of fuel.
I also put Seafoam in my oil a hundred mile or so before changing it.
Follow instructions on bottle. You can find it at WalMart or at most auto parts places.

I think Marvel mystery Oil will clean up the lifter a little better than seafoam. Drain off a quart of oil and put in a quart of MMO, then run it about 200 -300 miles, then change oil. Doug
