Hi, I am new to the forums. I just bought a new alcander 150. I was told to change all the fluids eg oil, gear box. Changed the oil It stays nice and clear now. The gear box oil i am trying to change now It is coming out thick with blobs? Is 80w-90 gear oil the right stuff to use? How do i get all the crap out first? Is there any other fluids i should change?The bike was Complete upon purchas, But took me a week to get it running, it would not stay going> Finnaly found out that the Intake manifold was cracked right from the get go. Replaced and it runs fine now just have to get the fluids changed. I would like to have it right before the kids ride. Any help appreciated.
