I've gone back using 10w-40.

All is normal agian.


THANKS!

======================================

OK, had Mystic synthetic oil 20w-50 for a year.It ranfine but as the 20,000 miles grew so didengine noise. (used Mystic from 58K to 78K)

___ Symptoms:
Clutch out, noise, pullin,none.
Tappets tinkled a little.
A type of "primary chain" whirrring sound.
FELT a slight random knock in the handle bars.
On acceleration, felt sluggish even when warm (20w-50).
Shifting gearstook some energy & was difficult to shift smoothly.

Changed the oil to non-synthetic.Used a cheap house brandof 5w-20 for thefirst flush. I planned a short ride maybean hourto flush the tappets and the followinghappened.
___ Symptoms:
Clutch in or out = no noise.
Tappets the tink was gone.
NO more type of primary chain whirrr, not even a whisper.
Random knock in the bars, GONE.
On acceleration, OODLES OF POWER! (probably the thin 5w-20)
Shifting,seemed to pre-think what gear I wanted & did it without effort.


So I kept this 5w-20 oil in for couple moredays of testing. I could not believe howfast, smooth & quiet it ran. On day 3,I change to 20w-50 using thesame brand ofcheap house oil as the 5w-20. 75%of the originalsynthetic symptoms were back though not quite asbad.

The Wings motor is aclose toleranced machine and with the5w-20it ran like a freshly rebuilt Singer.

Any suggestions as to why it ran so well with 5w-20?
Anyone havesimilar situations like this?
Should we be using 5w-40 or 5w-50 in our Wings?
Pros / Cons?

MikeF, you clicked ona lost memory of mine. :cooler:

All my past bike were air cooled which ran great on 20w-50.
All our trucksused 5w-50.
I'm over 50.

(must be a pattern here I'm missing)

Alzheimer's must be setting in... I'll have to remember that. (what's the string on my finger for?):doh:

Good thing this "cheap house grade" 20w-50was the #2 of 2 oil flushings.

I felt I was missing something so Ifigured I'dask fellow Wing'rz this question.I read through that HUGE oil postof 2005 and never read, or skim-read missed,the point of air-cooled motorsneeding thicker weight. That also mighthave clicked my memory.


Either way thanks!
What a GREAT WingSite of (unseen) BUDS ! ! ! ! :byebye:

I would say that at 20k miles, your oil was done.

20K on one oil change?:shock: OH GOLLIES NO.
I changed that oil 4 times in 20K (includes 2 filters).

Didn't think I had to write it but after re-reading my post it sure sounds like I went 20K on 1 change.

2-DAY I will be dropping that viscosity down.

Oh - disregard my earlier rant. I liked the line about CocaCola tho!

LOL, I missed that one, but it reminded me of...

I've learned many greattricks in my time, mostly fromfarmers. This one's akeeper!:cooler:

Here's a little rhyme as you ride down the road.
"When is my next oil change?". . . . OH, I know! :waving:


___ (by fvm 07-09) ___
Know what it taste likewhenyou start, you'll know when to change that oil.
Taste testing asmileage flows,souring as the acid grows.
And don't flirt with dirt or darkened oil, all the faster yourengine will spoil.

I hope this'll''HAUNT YOU'' like that tune you can't get out of your head.:cooldevil:


(this rhymeis now my signature, i guess "I LIKE IT!")

I used Castrol 10/40 and/or 20/50 ... Never had any problems described in FVM's post.

I didn't have problems as per-say, just noticable sounds that wern't normal.
Figured it much easier & cheaperto "ask now" than to "repair later".

Great concerns all, thanks.

Did you read my little dittie below?

Psst... a 1500 doesn't have a primary chain.

grrr, QUITE RIGHT. I'm thinking of my XS1100 again. :doh:

Boy-o-boy, I must miss that bike.



I should have said, "the sound of a dry primary chain".



Guess I better get a littlemore sleep, these "BoomBox vehicles" are getting rediculous around here, all day & almost all night.
