Greetings from a new poster, long time lurker. I have a 1993 ST11 with 36k on the clock. Had it for 10 years now. In the last year or so, usually after long rides or traffic jams, I would reach my destination, turn off the bike, only to find that when I tried to return to the road it wouln't start. I have to give it full throttle and crank repeatedly and it eventually sputters and comes to life. For the first few miles it won't take hard throttle. It stalls and dies. Afterwards it will go back to running flawlessly.
I've gone through the board and done most everything. Checked air filter, fuel filter, fuel pump (1200 to 2000 cc per minute, hot or cold). Brand new plugs. Local seafoam equivalent. Pulled the carbs and found a torn vaccum hose (PAIR and fuel shuttoff valve have been removed) so I replaced all four hoses. Put the carbs back on and synched. Runs better than ever but after a couple of sprints and fan cycles, I let it rest while I proudly started to dress her back up. Decided to start her up to turn her around and ...again! won't start! Am I rich? No fuel smell. Lean? Do I need to disassemble carbs? Help appreciated.
Thanks in advance!
