KLR 250 camshaft timing
I just picked up a '92 KLR 250, really cheap. There is one catch, the guy I got it from just put a timing chain on. He also cleaned the carb. Needless to say, it would not start when he was done (why it was so cheap). I have been throught the carb, it was a little scarey. The slide needle was not even in the slide, when I pulled the main jet, the needle fell right out of the bottom. of the carb. I got the carb back together, but it still won't start. Compression is right around 120, and the spark is strong. I suspect that he has the cam timing off 180 degrees. It has been a while since I worked on a bike. Here is my question: When the timing marks line up (facing each other) with the piston at TDC, the intake valve is just beginning to open, is this correct. How can I tell if the timing is 180 off? The timing gears are indexed to the cam, so 180 is the only option. With the spark good, the carb clean and getting fuel, and decent compression, is there anything besides timing that could prevent this bike form running? Any help is greatly appreciated. I have also charged the battery, so I know it has enough juice. I even tried to start it with a battery charger hooked to it.
