The dealer installed the Screamin' Eagle performance clutch when I did the Stage IV upgrade to my engine. I have always used Redline Primary case oil before in my bikes but I have put it in twice now and I cannot get the bike into netural when hot.

Dealer replaced the clutch once and put Formula + Chaincase lube back into it and no problems for 3000 miles.

I changed the oil in all 3 holes and put the Redline back in and now it will not go into netural.

What would be a better oil than formula+ and why is the redline causing this.

Thanks

 

Think it's a no brainer...go back to the one that works for you, formula +.

 

In my experience the oil in the primary hasn't affected finding nuetral. It's more a function of chain adjustment. Yours is automatic. Assuming it's working properly try a good quality synthetic gear lube in the tranny if you don't have it now. It makes a big difference in finding nuetral.

 

Make sure you are not overfilling. The service manual states that an overfilled primary may cause hard to find neutral issues.

 

It's possible the Redine makes the friction discs swell differently then the Formula +, and does not allow the clutch pack to fully disengage?

 

+1, I absolutely agree!
