Hi, I recently had this bike worked on to get it running, seemed to be running ok, took it to a ranch and rode it about 10 mins then it started cutting out and finally wouldn't restart.  I tried hooking it up to another battery and it started so had the battery recharged, when restarting with charged battery I tried the electric start (normally I kick start) and a mix of what seems to be oil and gas came out of the front pipe or crankcase (can't tell which) and bike won't start.  Knowing that gas  in crankcase is bad but not knowing if it is really gas or more oil, and because the bike was running recently, can't figure what has triggered this leak when starting, any ideas?

it sounds like the crankcase is flooded, turn off the gas, take out the sparkplug and spin the engine over to eject some of the fuel, than leave it overnight to evaporate off...that's what I'd do anyway. hey, first post all about a problem!...what no intro / hello?
