EXactly the right place to start! 9 times outta 10 something weird after the dealer touched it.... look I just had them do a tire change, same tire dunlop stock HD tire and my drive belt is on much looser than originally. I'm gonna have to tighten it myself and avoid them for a while again.

BTW this is the first negative feedback on amsoil I've ever heard of.

 

When i first get on it cold it's fine but after is warms up on the highway it clanks really loud every gear. It wasn't bad until yesturday when it was about 90 degrees here instead of 65-70 and it was BAD. I've been running the gear saver and if i pushed the shifter down just right i wouldn't even get a clunk going into first. And it was silent when shifting up the gears, and if you throttle it right silent going down the gears. As soon as i get paid i'm going back.

 

I run Amsoil 20W50 in the engine and primary and Amsoil Severe Gear 75W140 in the trans, works great for me.

 

Who put the oil in you or the shop? Maybe you paid for Amsoil and got Wallyworld no name?

I run Amsoil 20/50 in all holes, imo the tranny shifts smoother than the stock HD oil did.

 

Try Spectro Six Speed tranny oil. That is what I use. Made a world of difference. It is expensive. But what is 5.00$ compared to 1600.00$ for a new tranny. Look at there web site. they will deliver to your house if ordered online. Spectro Oils of America. They also sell a primary lube that I use. In my own opinion they have the best....

 

I switched from the Amsoil to the Redline Shockproof.

Didn't really have a problem with the Amsoil except being able to find it locally when I needed it.

I've been real happy with the Redline.

 

I went in to get my primary bearing replaced a second time, and they replaced the cases for the trans and the inner primary and replaced all the bearings in the transmission. They did put in the AMSoil cause it looks like it on the stick and it was listed on the invoice. I can tell it's a Oil issue because it's fine cold and around town a little but once you ride on the highway or it's hot out the trans starts banging which it didn't do with the Gear Savor. My bike did the exact same thing with the original fluid from the factory and as soon as I did my first oil change and put in the Gear Savor it stopped. My wife's 07' Dyna was the same and stopped when i changed the fluid to Gear Savor. So AMSoil in my bike acts the same as the crap from the assembly line. As soon as I change it back i'll let you know if it stops banging.

 

I'm running the Spectro 6 speed platinum also and it smoothed it out pretty good.

 

R Racing had some issues with it a while back:

Redline now makes a V-twin blend - one for the tranny and one for the primary

I went for a ride today it was 65 degrees out and the trans was perfect and didn't bang like it did when it was 90 + out. It was just as quiet as the Gear Savor. I guess the AMS oil just doesn't like the heat.
