There has been some discussion here about using Redline oil in the trans of our bikes. This subject came up today while talking to the local wrench who does all my motor work (along with trans work!).
He has stopped using Redline heavy duty shockproof (the RED stuff) in the late model transmissions. Seems he has had a couple of trans issues that he believes were caused by a "lazy shift drum". Theory has it that MAYBE the heavy weight oil, on cold days, not allowing the bike to warm up properly, is causing the shift drum to lag a little on quick shifts. Remember, MOCO uses Syn3 in their trans.
Again, this is just a theory, but, he has switched to a lighter oil (Blue) for the late model bikes.
I believe that some customers are not letting their bikes come up to temp, finding a "false neutral", then dropping the hammer! We have seem some broken gear teeth with the bigger motors (last victim was a 124 S&S). Food for thought, huh?
The older bikes, and the Baker gearsets still get the red (heavy duty), but, the new bikes will now get the lighter oils.
Please be aware, I'm not bashing Redline. I use the Red in my Baker gearsets, also in my old 4-speed, but, I will switch to Blue in the '09.
I find the '09 does not shift as easy as the older bikes, but, that may be due to only 8000 miles on the bike, OR due to using Red in the winter.
If there is anyone else that has experience with trans oils, it would be nice to hear from you all.
I guess the debate about who's oil is best will never die!!!
