Clutch adjustment after switching to synthetic

This doesn't make any sense to me and maybe someone can explain. My bike has almost 1200 miles now. Decided to switch to synthetic so picked up some Amsoil 10/40

Drained the oil, changed the filter and put the new stuff in. Started the bike and let it warm up. Jumped on to take a quick spin around the block but when I put it into first, the bike lunges forward. Doesn't die out but I can feel it wanting to move forward like I don't have the clutch pressed all the way in. Weird, it was perfectly fine before I did the oil change. I took it for a spin just before I drained it. I had just adjusted my clutch at the 600 mile service. So I proceed to adjust my clutch again and problem disappears. Why would switching to synthetic throw my clutch adjustment off? Did a search and seems like I'm the only one that experienced this. Did @oldgixxer also put a curse on me when he threw me out in the cold for a bit?

1. This is the first time I have heard of anything like this.

2. OG and OF are both 7th level Voodoo witch doctors so anything is possible.

OG definitely put the hex on you because there is no way switching to synthetic would change your clutch adjustment.

I knew it. I have a pastor coming over tomorrow. Hopefully he can lift the curse. 😁

Nix the Pastor, you need a full blown Catholic exorcism.

Re: Clutch adjustment after switching to synthetic

I experience a lot of clutch drag when I put new oil in. But never have to adjust the clutch.

I am not sure if it is related to the new oil directly going onto the clutch plates as it is poured into the filler hole or some initial reaction with the fibre plates to the new oil.

It only lasts for a few clutch and gear activations and disappears after that.

There must be some truth to that theory as I'm know I'm not going crazy. Not yet at least. I didn't ride it long enough to see if it disappears but readjusting the clutch did put it back to how it originally performed. My first thought was, I got sold some bonk Amsoil. None of the dealers or motorcycle shops around me carries the stuff. I did a Google search for Amsoil dealers near me and came across this dude who sold it from his garage. It was an older gentleman who looked like a poster boy for Amsoil. He had a shirt, hat and huge Amsoil stickers on his truck. Lol. After the readjustment the bike does shift a lot smoother now

Amsoil is multi-level marketing... AKA a pyramid scheme.

I read all about that. Pretty much anyone and their mother can become a dealer. At $11 a quart it was actually cheaper than any other synthetic that's carried here at my local shops. I think I'm switching to 300v after this as it's much more accessible and heard great things about it. I'm also interested in Rotella. Nothing can beat how easy that is to get.

Re: Clutch adjustment after switching to synthetic

Yes, it's a really weird marketing structure for a supposedly high performance oil that beats

everything else in existence (Amsoil's claims)

Re: Clutch adjustment after switching to synthetic

I had an almost new R1 that would do something similar. Fully synthetic oil causes noticeable clutch drag, while semi-synth was ok. The difference in the oil affected the clutch performance.
