Hey guys first post on here. I've had my bike for about 4 years and I re ringed it friday. Everything went good and we gotter back together and now it won't start and run. You can hit the throttle about halfway down and it'll will like sputter everytime the motor turns over but it never will catch and run. Can anyone help me with this problem. I'm in desperate need of it to run. We gotta get some cows up. Thanks in advance.

I'm going to have to agree with Helmut.... there is an issue with the rings. a compression test will quickly determine that.
have you checked compression?? and make sure the key is on and the red slide lever is on.

Do you have a strong bright blue spark?
Did you forget to plug something up?
You did install the rings correctly didn't you? there is a up and a down to them.
IF you ringed it correctly and cleaned the cylinder up good you should have more than 90 on the compression I would think? maybe somewhere around 110 to 130? you may have an issue in the head?
AGREE!!!!!^^^^^^^^ saves on headaches too!!
