Right, My bike shat itself... and I need to decide if I want to take it in for repairs or should I try my hand at it (With help from the old boy no doubt). In a nutshell - bike dies during riding, wont start - starts after 5 min - Loss of power - oil coming out under the left engine cover - oil on boot - oil level "ok" while hot (waiting for it to cool) - oil on the exhaust pipe near engine - possible clunking? Was coming home from work, mainly 60 zone with a few 80s and 100s, traffic was flowing well so heaps of air flow. Come to a stop after an 80 zone at the lights and the bike just dies. It turns over but doesnt start. I do the embarassing waddle across 3 lanes of traffic, get it off the road and let it cool down a bit even though the temperature gauge was just over "cold". As it's cooling I checked the oil level and was fine (granted it was hot). A bit of smoke coming from the left, looks like there's oil on the exhaust pipe as it comes out of the engine. After 5 or so minutes it starts again but it sounds a bit clunkier than normal (perhaps i was paying more attention). I ride it back, gently easing it through the gears and up to 60. It struggles a bit, even at 7k rpm, ie close to pinning the throttle to keep it going. 1.5km or so it dies again but i'm almost home so i give it another shot. Had to get the choke in to get it going this time. Just as i'm pulling up at home my left foot slips off the peg, check the boot and there's oil on it. Bit hot too touch at the moment but the bottom of the left engine cover is quite slippery. I'm hoping it's someting as simple as a gasket. The only other thing that comes to mind is that i rode it with the choke on for a bit too long a few months back, only realised when the engine temp hit 3/4.
