Don't you think some information would be helpful. Can you work on it. Does it have gas, spark, clean filter, compression, how many hours, and checked the valves.

Yes I can work on it. It has gas,compression,filter is a little dirty. It ran good 4 days ago. I just took off all the finders and stuff to clean them and when I put them back on the bike would not start. :bang:

Clean the air filter. Check the valves. And stop beating your head against the wall, it will not help, usually.

Yes it has spark I took off the boot and put a new spark plug in to see if is had spark. But I cant replace the plug because I dont have a plug tool I have to go get one. The plug is down in the head

unplugged a wire somehow, ground wire grounding out, compression not as good as you think, gas tank empty/not enough, petcok off, valves tight, rag in air intake, all things ive seen happen.
