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?

[roadiemort]

Glad you got it fixed.

If you just added oil then I’d change it again. That new oil has now mixed with what little sludge, along with metal shavings, that resided in there and is circulating that mess through the cross shaft bearings. The transfer case does have a pump. (#11)

I haven't checked or changed mine in 6 years, but I only rode 8000 miles. Who knows what it was like when I got the bike. Maybe I should look into that if I keep it.

The transfer case gears and chain don’t turn when running in neutral do they? I had a similar noise and changed to 10-40 synthetic instead. Solved the problem. Is your area of the US hot enough to justify 20-50?

[Bikerron]

Seriously?

No. They are directly connected to the drive pulley, belt and rear pulley. It only turns when the bike is rolling, no matter what gear or coasting in neutral.
