Always a tough one to answer because of all the different Co's selling lub.Pick a brand that is easy to get your hands on.Amsoil for me.

 

mobil 1 20-50 in all 3 here

 

Mobile 1 in all 3 here? Or Mobile 1 V-Twin 20-50?
I use V-Twin, but have heard of people using just the Mobile 1 with OK results. I prefer to use what the bike should have and what the product was intended for.

 

Redline Shockproof heavy for me.

 

Got a questuion on some of the replies. Redline has introduced a snythetic, V-Twin transmission with shockproof. Anyone use it ? Does anyone know of any difference from regular shockproof.

 

My 07 Road King Classic has 20,000 miles and is out of warranty. I found out I have a transmission oil leak that is showing up at the rear shifter shaft. This is a common problem I am told. I have been using Harley Davidson synthetic. I am wondering now if a heavier oil in the transmission might prevent this common oil leak.

Thanks,
Rick
