Hi guys, I will give a quick sumary of what I have done to my bike and how it has behaved after such works and will be needing info if possible because something is NOT right!!:huh Shipped bike to USA to do TAT,went great,loved it etc but last day lost 6th gear,no big deal. Shipped back,engine rebuild to replace shift drum. Tested bike,ran lovely but had a stumble at 2k revs and 4.5k revs. Cleaned carbs,changed plugs,changed plug caps etc but no joy. Got my second set of carbs and got them ultrasonic cleaned to clear immulsion tubes so as to not have the same problems. Built carbs back up(jets etc),put them on the bike,checking TPS etc on build up. Front carb was spitting fuel up from intake(seems to be blowing instead of sucking) but balanced the carbs til it stopped and seemed ok. Built up rest of bike and it ran good for about 5miles. Stopped at my brothers to say hello,tried to start,wouldn't start without throttle,ran like SHIT back home(1mile). Stripped it,spitting fuel on front intake again so stripped carbs checking all jets are correctly built,double checked air screw,TPS,etc,etc. Something else I noticed was that the front cylinder pipe doesn't seem very warm.....bloody odd!! Any idea's?? It's probably something real simple but i sure cannot find it. Thanks in advance.....just gonna go lift some heavy weights 'cos i am severely hacked off!!! Thanks in advance.
