My bike pretty much sat in a hot garage for a little over a year with gas in it. I've only started it a few times during that time and rode it down the street and back and didn't have any problems. The last time I rode it was about 3 months ago. I replaced a clutch cable, test drove it down the street and then left it. So I was thinking of taking it out this weekend and wanted to make sure everything was ok. I wouldn't start. I used some starter fluid and got it started pretty easily but wouldn't idle. I didn't need the started fluid once it started the first time. I was able to get it going but it kept cutting out and stalling and then was hard to start. I could get it to idle if the choke was on but not without. Then it died and I couldn't get it started. I found the fuel line between the tank & carb was cracked. I figured air must be getting in the line. I replaced it but it still wouldnt run. I could spray starter fluid in from the air filter and it would start but then die. I couldn't get the spark plug out but knew that was part of the problem but I also thought the carb might be clogged up. I took it apart and cleaned it then put it back on. I didn't take off the tsp. Still wouldn't start. I could get it to fire with starter fluid but it wouldn't start. I got a tool i needed to take out the spark plug and the hexagon and metal shield were corroded pretty bad. The nut and the electrode looked good. I cleaned it with a wire brush and put it back in. NOW THE SCARY PART!! I tried to kick it but it felt like I had already pulled in the compression lever. I tried it again and it kicked thru. It always stops when at top and I have to pull the lever, kick it down a little, let it up and kick it thru. Now... I can push the kickstarter down with my hand. Its not easy but before it was impossible. And it still wont start. Im worried that starter fluid was a bad idea. Ive used it forever and never had a problem. What else could it be or how can I fix it?
