Default Quick oil change ??

Hey all - Dont worry, this isnt a 'what oil to use' question. I changed my oil to the Syn3 in a three holes. I have noticed a ton more noise in the engine since and I want to get that crap out and put in some Amsoil.

My question is, I have 250 miles with the new oil, do I need to change the filter too? I would assume so since there is residual Syn3, but if I can avoid taking that PIA filter off that would be great.

I get a lot of good info from the site, thanks in advance..

If you leave the old filter in place, you will leave synthetic oil in the system. That will dilute the new oil, so change the filter.

Any noise you hear after the change-out probably isn't from the motor itself I would think, (others correct me as I'm new to the HD motorcycle), or there is something very wrong.
I just changed my tranny and engine oil the other day when I got my new bike home from the 'States. I used Mobile 1 20W-50 synthetic for the engine with a new K&N filter, (easy to get off without a mess, I got a shopping bag and pulled it tight from the other side around one exhaust pipe). Now, onto the tranny. I used Redline, (small town, nothing else readily available), 75W-140 and it explicitly says on the bottle not to be used for manual trans, too slippery and will cause the gears not to sync. I don't know, but it might be wishful thinking but the shifts might be a tad smoother with less clunking. I also have a 2007 Goldwing and sometimes I really don't know if it shifts or not it's so smooth!
Now I wonder if the different sounds you're hearing is from the trans, and also I'd change the filter because when you're dealing with such a small volume, there is still a lot of residual in the oil passages and the filter itself.

I would go ahead and change it. A filter is cheap and you may as well get all the oil out that you can get, and there will be a significant amount in the filter for sure.

Not necessary to change it. The syn3 won't hurt anything and all synthetic oils will transmit more mechanical noise. This is normal.

Why does the synthetic make more noise...I guess I always associated to more noise = more metal on metal.
