85 200x motor issues

[RDH/86200X]

ok so i just rebuilt the top end of my 85 200x and got the bike all put back together. it ran great but then devolped some issues. the first was the kick starter stoped returning at all. but now it returns with out a problem so im a little confused. second when i try to start it sometimes it kicks back and when it does so there is a very loud clank sound coming from the bottom end. third i checked my oil and it has a creamy metallic color. so i have all ready decided that i will not be riding it intill i can afford to fix what ever is wrong but with out spliting the cases i have no idea what could be the problem. if anybody has any idea's what could be wrong please let me know.

if that creamy color is whight or gray theres water in it and its damb near usless the metalic color is not good im thinking your bottom end rod bering may be gone cause the klank sound but its hard to say cause i cant hear it or look at the motor over the internet but i think you got magor isues
