I hit 5k so thought that I would go with Amsoil at the oil change from what I had read and heard around from various stealers talking with other riders. Wow what a big difference it made. It seems to run a hell of a lot smoother with more a lot more response. It was hard to tell about her running cooler being that it was only abot 60 deg when I took her out.

I was still been running the SE stage 1 filter so also I changed that to a K&N along with a K&N oil filter. I can hear her sucking air now, where before I could not with the factory paper filter. Maybe it is just me but she really seems to run a lot better. I know I am going to change over all fluids with Amsoil for the baby soon! I DO Not represent Amsoil, but I would consider it. $

 

Amsoil is the heat. Also check out the Scavenger on the Rogue Chopper website. I run Amsoil and my temps this summer were 200-210.

 

With all due respect, I cant believe that a simple oil change will make it run smoother, faster, etc, etc. Cooler and MAYBE quieter I can see.
Its just oil.
If it works for you and you like it, thats great.
I use what works for me. No brand names. JMHO

What he said...

 

I think the real reason its running better has more to do with what your hearing and the new K&N filters less restrictive effects on the intake than the oil.
Not saying the oil's not a good thing, Amsoil and other synthetics are great for lubrication and cooling. But for noticeable performance increases its the intake that's going to give you the most bang for your buck. Provided you make allowances for increased air intake with the fuel management system.

 

I switched to Amsoil at 1k and noticed an increase in mpg by about 2-3 around town. I put it in all three holes. Can't say I noticed any other differences with it.

 

I run regular oil and the temp gauge stays around 195. I did see 200 in Fla.

 

when i switched i had 1000 miles and it does make a big improvement. my temp dropped from 260 in the summer to 240. The engine ran smoother, the noise from the counter balance was quieter. I did not use amsol in the trans. I used bel rey gear saver and it made the trans easyer to find neutral and the 5th gear wine was less. later i did a stage 1 with dynotune and the temp dropped to 200-220. Mobil one has a new 4 stroke MC oil I am going to try next time because amsol has gone to $15 a quart and mobil one is $9

 

If you switch from regular oil to synthetic oil, if anything it will be noisier. Regular oil stays thicker and that helps muffle some of the engine noise.
As long as you are using the proper weight oil, there should be no difference in performance. Doesn't matter if it is dyno or synthetic. Many years ago, you could tell a difference, but with the newer dyno oils you wont be able to tell. The advantage to using any quality proper weight synthetic oil is the longer life and consistent lubrication at extreme higher and lower temperatures.

Ditto that. Irrational exhuberance...
