At the recommendation of Baker Drivetrain I put Red Line Heavy Shockproof in my trans (put H-D Formula+ in Primary) ,
I've been wondering , Has any one put Red Line in there primary? If I had what would have been the results?
With all this Global Warming going on I may not get out before late April to enjoy my winter mods

 

Redline Shockproof in the primary? Hell no don't do that. But if you mean the Redline primary specific fluid, Ive used it before on stock clutches but I usually run Rivera Primo clutches that call for type F ATF fluid. The primary fluid is generally determined by your clutch pack more than anything else. If running a stock clutch then Id say the Redline primary fluid is good to use, If running an aftermarket clutch use what they suggest.

 

Redline Shockproof Heavy in the transmission
Redline MTL in the primary

 

Shock proof will will eat the clutch up .just seen pics of some that have tried it on sporsters shared primary & trans.

 

As I sit here looking at global warming (another ''3 of new snow) I want to thank all of the previous responses , Pretty much an open & shut case of good thing I didn't vary from the FMC on that one (not saying there's not some thing better than Formula 1)

Let it snow, still want two more weeks of sledding. Then I'm ready to hear the hog and change all the fluids plus tires & rotor for rear waiting.
