Let's beat an old horse one more time

Ok - here's we go again.

 

I was told that once I used Synthetic, I couldn't go back to regular oil. Should they have said SHOULDN'T ? instead of couldn't ?

 

Doesn't matter, neither is correct. Many have gone back and forth with no problems.

Thanks - I wasn't sure about his intimate knowledge of oils

I've been changing oil twice a year with about 1000 miles between. Last year I changed the oil and put in amsoil with the MotorKote additive. The whine became unbearable at 55-60 mph so I dumped it out and put mobile 1 back in. Now the whine is guaranteed to show up at 55mph and yesterday a chirp showed up.

Tomorrow I'm going to change oil again and this time I'm going to put Mobile 1 20w50 in it. It's really getting aggravating when people on the street stare at you and I know I'm not THAT unattractive, nor is my Venture.

 

If anybody has any theories on this I sure would be willing to try them. I haven't bought the oil yet but I will tomorrow.

 

Thanks in advance

 

Make sure you know what you are putting in the bike. I have used this in the Venture since I bought the bike with no issues at all:

I have used the Mobile 1 V Twin 2 times in my Venture - wasn't happy with either run.

 

I just put in Suzuki Motorcycle racing oil that my Yammy shop recommended, still have a whine but I 'think' it's a little quieter.

 

If it (whine) get's annoying, I'll try the Mobile 1 Racing 4T - not sure I've seen it anywhere tho -

With all the comments about different oil formulas to get rid of the whine, has anyone ever tried adding a little STP?? Haven't seen or heard of it for a long while now. Does it still exist, or am I showing my age??? I guess it still does, but it don't look like it used to.... STP OIL TREATMENT

My 83 VR has a little over 50,000 miles (84,000km)

It has a definite chirp that sounds like it's coming from the rear end...and of more concern...the only time I hear the whine everyone is talking about is on corners.

 

Could it be a rear bearing on its way out?

If the whine is every time you lean into a corner then I'd be more apt to say it's tire whine. Some brands of tires whine a lot when leaning into turns.

Is it wet clutch frendly????

 

 

I normally do NOT put in any addatives to my engine oil.

No - this darn thing wines sitting still - then it gets worse as the speed increases - 55 mph is the worst area and cruising at 65 70 coming back from RT was a real pain in the ear.

No, I was addressing that to shaynes comment about his bike.

sorry...didn't mean to steal the thread...I thought it was sort of relevant.
