The bike is a GSX750F 2002 Model. Here is what happened during the last 2 days (before this the bike was fine). I had an oil leak so I jet washed the front of the engine to remove all the oil and I found the oil leak, it was on the oil drain tube . I fixed this by using JB Weld. 2 Days ago I was riding and I filled the bike up with petrol, riding home that day I heard the bike sound strange (beefier) it sounded borderline harley. The bike was also losing performance power and when I dropped the gear down the bike cut out... It started up after a few tick overs, and I continued my way home normally. Today the bike did the same, but it happened 5 times on the way home (the last time I had to use a booster pack as the battery had fulled drained due to the engine constantly ticking over and not starting). To get the bike started again I would have to put full choke on and keep my finger on the starter switch. I have no idea what the issue could be... I have checked the bike battery while revving to 3k, and I get 13.70 volts. It is currently sat in the garage and will happily idle.. as well as rev healthy, it is strange.. Thanks for any info!
