Oil to use.

[ItBeMe]

Ok this has been hacked over one million times. I have a 2005 Roadstar with about 70,000 miles. Now I am hearing gear noise in the trans when it is cold, after it gets good and hot the noise goes away. Can that be the oil I am using. Castrol 20-50 synthetic T4. Does anybody have or had this happen on they're bike. It is due for a oil chance so I am thinking about changing oil types. What do you guys think.

How often donyou change it? Try another full synthetic vtwin oil....and change every 3k-4k. Mobil 1, Amsoil, Quicksilver, Rotella T6....maybe also try flushing your engine with a quart of diesel and 3 qts cheap oil and some seafoam.....run it for 20 miles and drain thoroughly then put good oil and new filternon

The noise is probably coming from the transfer case, change the gear oil in it.

Where is the transfer case and what kind off gear oil does it take.

Never mind I went on You Tube, I will start there.
Thanks everybody for your help.

Any special type of gear lube that works best. ? ? ?

Ha ha ha. “What oil to use” threads just aren’t what they used to be. Nor are pet rocks or beaney babies.

FYI - I use Royal Purple gear oil. Many years ago Royal Purple oil was the bee’s knees.

If the transfer case is not the culprit check here next.

Checked the gear oil and it was about bone dry. Don't know where it went. Filled it up to the proper level and noise is gone.

Did you check your front sprocket and make sure it isn't seeping around there?

Glad you got it fixed.
