Johnjzjz said use the 30 weight lawnmower oil in the forks, says its a vast improvement. Ill be running that in my 66. Not sure if it would apply to my TWINKIE but I might try it.
Apples and Potatoes... But, Report back please... BTW Note that "lawnmower oil" is really just straight weight oil... most suppliers have it...
Oh... and it is probably Non-Detergent..
ive used straight 30w ...ie "lawnmower oil"in my Norton roadholders for many years with no probs...so after seeing that post on what oil for my FLH i wasnt surprised to see it recomended for a FLH front end............BTW when i gave my 1982 FLH its 3500ml service the oils that drained out of the forks were of two different colours... and im thinkin its factory oil...one green, one red...whoda thunk it ??
