Be careful with group iv and v synthetic in primary

I was at Thunder Beach this weekend and my clutch which has been giving me problems packed it in. I just turned 10,000 miles and I have been adding power mods. As the power has been coming up I noticed the clutch will slip a bit above 3,500 rpms when you are getting on it.

I just had the 107 and the heads done and the bike tuned. It runs great and was slipping more.

I put Redline in the primary at about 3,000 miles. My clutch was burned or scored because it couldn't hold with thar excellent fluid.

Anyone else experienced this?

Interesting, I wonder if its an oil thing or a clutch thing, Fuel Moto recommends a lockup clutch for their 107 builds, AIM I think.

I had the same problem. I use there oil & trans fluid. I then went with there primary fluid. My clutch started to slip when shifting around 4,000 & above in the taller gears. My tech asked me what WTH was I using, all brown & nasty looking. Went back with HD Formula+ & that solved the problem. I'm a big fan of Redline. I gave them a call & talked to the tech & was told my clutch must have need to be adjusted. It was when I had my 10K service & put in your primary fluid. He then told me no one else has called with this issue.
Really!!!!

dont waste your money on synthetic for the primary. i use shell rotella t, costs about $13 for a gallon of it. at 38ozs per pop, i get 3 complete fluid changes out of it, with enough left over to top of the 38oz a couple of times on the new bottle. plus, its jaso rated for wet clutch application.

used it exclusively in my fm 107 build along with the aim vpc92 and had not problems.

I understand the concept of reality, but find it too confining for a way of life.

Same issue here on my 2012. I'm starting to think it is the Synthetic oil (Redline) in the primary. I'm 100% sold on synthetic in the motor and trans. Not sure on primary......

Might give the formula+ A shot and see what happens.

Don't use synthetic in the primary. It can cause slippage with the clutch. All the primary oil does is lubricate the chain and clutch. You don't need synthetic in there. It's like pouring Dom Perignon down the drain.

Interesting. Glad I am not alone. The HD tech put the syn3 in the primary when he had me all put back together. All seems to be working well now with the upgraded spring.

Another question, my Harley Master Tech who has build all four of my bikes does not like synthetic, other than Syn 3 in the motor. He says it build up Lots of carbon.

Any of you ever hear this?

Thanks

I've used Redline in the primary with no issues , not saying there isn't an issue though ..

Your Harley Tech is trying to sell you his oil , the Harley Syn3 is a blend , not Full Synthetic ..

When Full Syn became readily available back in the late 80' to early 90's , I was told , it would gum everything up and clog the oil filters , then low and behold Harley started using it themselves

The problem is not synth oil, the problem is some oil has friction modifiers (low friction energy saver) that is where those clutches problems are coming from if adjusted properly, look for Jaso certification ( compatible with wet clutch) on the can you will be fine. I use to have a rice burner with 150 horses running full synth oil never had a single issue and i was dumping the clutch in the 6-7k RPM often and never slept on me: -). Today's rocket have 200 horses and running full synth, my 2 cents
