A few weeks ago I made a post about letting the bike sit for about a month during winter, and it wouldn't start.
I had to rip the carbs out and clean them.
The bike worked again.
Well.. I did it again.. :sigh:
I let the bike sit again, long enough for the battery to die.. I think I needed a new one anyway.
Well, I pull it out today, and try to jump start it off my truck.
I have the choke all the way open. It really didn't want to start, but I keep trying.
I finally get it to run with the choke all the way open, and the throttle open, revving about 7-8k rpms, smoke blowing everywhere.
I noticed some liquid coming out of the right header pipe where it mounts to the cylinder. It looks black in color, but smells like gas.
It's backfiring like crazy, fire came out the muffler, smoke is blowing everywhere.
It won't stay running.
Do I need to tear it apart and clean the carbs again?
I would say definately yes on the carb cleaning. Carefullly inspect everything. Look for a reason why the carbs might be failing. Rust,debris,varnish,bad o-rings, scored/worn/stuck float needles etc etc. If your batery was stone cold dead it will never hold an adequite charge again and needs to be replaced. If not check the water level in the batery and put a voltmeter on it before installing it to confirm a porper charge. If you were seeing flames and smelled gas like that I think you were running way rich. Or maybe you cylinder filled with gas somehow. :dunno_white: Is the gasoline really old? Maybe pulling the plugs and lookin' in with a flashlight could yield some useful info.
Btw I think you need a new exhaust gasket now too.
I used to fly remote control planes and you can bet the gas with the oil in it will gum up quick. So this is what we did, you've probably done this but what the hey. shut off pet chicken, put in fuel stabilizer, start bike till it runs completely out of gas then spray in "After Run" then try to start it. It won't start and it will stop the residue gas from gumming up and turning into carmel in the carbs at the needles. You may be able to find "after run" at a hobby store for 2 stroke engines. This is for when it sits awhile. I'm a newb here so if you've done this and it doesn't work, I'm an ID 10 T. -idiot

damn you're freakin' smart. that was exactly the problem. I finally got a chance to tear the bike down again, and pull the carbs apart. low and behold the needles seemed like they were super glued LOL
Thanks for the insight, it got my re-motivated to do it myself!
