+1 for red line shock proof heavy in the trans. I run harley dino in my motor and primary, but there is a big difference from red line to syn 3 in the trans

 

I still run dino in mine no issues with heat. But I run Spectro oils.

Heavy Duty 20W-50 in the motor in the primary I use the Heavy Duty Primary Chaincase Oil and in the transmission I use the Heavy Duty Gear Oil 85W-140.

Talked with the guys from Baker Drivertrain at The Horse SmokeOut and they recommended it and I thought if they that are smarter then I am think this is a good product then I might give it a shot. Never been happier. Motor runs cooler the the HD stuff and the primary doesn't sing and the transmission shifts smooth and easy.

 

When you hit 10K, (or do yourself a favor and do it sooner), put ATF in the primary and Redline Shockproof Heavy in the tranny. It will make it a lot easier to find neutral and shifting smoother.

 

Unless things have changed, synthetics DO NOT extend your change intervals. I had 3 fast lube centers for over 10 years and the only synthetic that would make any claims for extending change intervals was Amsoil. They would only extend them if you used THEIR branded filter. The Amsoil website specifically excludes modified engines from extended change intervals.

Modified includes.... "Engines operating under modified conditions are excluded from extended drain recommendations. Examples include the use of performance computer chips; non-OEM approved exhaust, fuel or air induction systems; and the use of fuels other than those recommended for normal operation by the manufacturer"

Notice..... "computer chips". This could be interpretted as a SERT, Power Commander, Thundermax, etc. Also....."non-OEM approved exhaust" would be any exhaust other than stock or certain Screaming Eagle exhaust.

 

Went from Mobil 1 to Redline in all three holes. I can tell the difference. Redline is better for me. I got 15,000 on bike. just my 2cents.
