Ok......so I put new timing chain in bike and had dealer look at bottom end when putting timing chain on and they said it was good to go. Original problem was loud noise and kickstarter not going down more then half way without the use of decompression lever. So I put bike back together and put the right amount of oil (1.8 Us Quart) back in bike and the problems started again. First of all the oil level was all the way up to where the dipstick screws in. Yes I drained all the old oil out because I had both drain plugs out and I had case covers off. Then I decided to try and start it and the damn kickstarter only goes down half way and will not start. Will not go all the way down without the help of decompression lever. &%$#@!? Motor was put back together step by step and timing is dead on. New timing chain, piston, rings, wrist pin, gaskets. I am getting fed up with this bike. Please help. I think it might be the head now or the bottom end. Has anyone had this problem?
