Please only M8 experience replies - other threads on internet forums I saw on this issue deviate quickly from the question. I am very curious to hear facts from you other M8 owners as to are YOU having any Oil consumption issues --- OR --- are you Not seeing this with your M8?
This post is pre-dealer visit as its Sunday and just returned from long trip. This my 4th RG in 20 years, I do ride pretty hard and long trips often but never had a Harley burn oil in all those years till this M8.
My story ......bike is 2018 RG Ultra, had dealer add Stage 2 Cam kit before I drove it home. Had 1000 mile service done. Then multiple day trips and at 1850 miles I checked and fluids were perfect level. Just returned from a 3535 mile trip over 13 days, and consumed 2+ qt. oil & 3.5 oz. trany fluid!!! Rode thru Idaho, Yellowstone then to Deadwood for rally. I never rode it in hot part of day, 55F to 90F riding temps the whole trip. Yea I read all the transfer fluid issues that's why I have been checking trany too.
I "check" oil as per manual, run for 2+ minutes then turn off and check on jiffy stand. Sometimes run bike for 10-15 minute ride before checking.
I checked oil after 1650 mi. (3500 mi. odometer) and was 1 qt. low and added the qt. Added and re-checked next morning and all good. Trany looked just below mid range so left as-is.
Checked oil after ~900 mi. more and was ~1/2 qt. low so added and rechecked cold next morning, all good. Trany looked OK still.
Go home yesterday, checked and clearly 1/2 Qt. low so added it, then checked trany and was way low... added 8 oz. I rechecked both cold just now and ok, but still little low on oil, trany back to good level. .
I am so very happy with this bike, best ever in so many ways, but extremely concerned if and what may be wrong here.
