i got the bike and it was not running the best. I cleaned the carb and put a new carb kit in it. And it runs good now. I have an oil leak for the three way breather line, my question is as to why I have oil leaking out of this line? I really do not under stand the purpose of it either? One end comes from the left crank case, another from the cylinder head cover and then the top part on that t goes to my air box.
Also as I was riding it seemed to cut out in fifth gear like it may have been cutting out in the top end of the rpms. It definitely was in fifth gear but just got it home as I saw that I was leaking oil out of that breather hose. Any clues on that would be great as well.
Generally, lots of oil from the breathers means lots of blow-by at the piston(s). Hopefully the engine is just tired, worn rings and cylinder wall; not a cracked piston or gouged cylinder that has to be replaced. It would be nice to get compression readings, but if this has a kick-start then it probably has a compression-release that makes taking compression tricky to do.
As to the misfire, what does the spark-plug(s) look like? Post pictures...
