Any specific issues with synthetic in the early models with 5spd? I've read the early 5spd models had Andrews gears any issue with those and synthetic?Īlso, since tomorrow it likely won't be warm enough to get rid of the ice & snow on the ground in places around here, any issue running her on the stand in 4th or 5th gear at just above idle to warm up the primary and transmission oils prior to draining them?Īccording to the BDM service manual, synthetic isn't recommended for the transmission, but I see that many of you are running it. They were blowing out their supply of Royal Purple gear oil for $3/bottle, so I grabbed a few bottles along with 2 quarts of the HD primary/trans oil.Īccording to the BDM service manual, synthetic isn't recommended for the transmission, but I see that many of you are running it. As for the rear diff, I am also using 83222282583 BMW Rear Axle Fluid (SAF-XJ + FM Booster) as this fluid came out in response to the rear diff making noises and things. If the heavy grade is equivalent to a 75w/240, wouldn't the light grade be plenty. I am having a hard time finding Red Line Shockproof locally, and only found it in light and superlight grades. Yesterday I stopped at the local Harley dealer to pick up the oil. I would use the 83220309031 OEM BMW MTF-LT-2 in the SMG transmission, as you dont even know if the other fluids is rated for the SMG. ken4ahog said: I saw a thread where many Harley owners run Red Line Heavy Shockproof gear oil in their transmissions. now it's time to tackle changing the primary and transmission oils.

I finally got the Badlands Pro III lighting module installed ( ), figured out how the PO screwed up the rear lights and fixed it ( ), got the new rear tire installed, belt tension set, and aligned the rear wheel (they had it way off).
