I have a 1997 yamaha thundercat that's in pretty good shape. The problem is when I drop the throttle the revs drop to about 1k then slowly keeps dropping until it stalls. I've tried using the idle adjuster screw; turning it up makes the revs stick at around 3k and not drop unless I let the clutch out and turning it down makes the revs drop and it stalls quicker. I've had someone check the carbs and there are no leaks. Any suggestions? My wrist hurts because I need to keep on the throttle at the lights. :C thanks

A week or so ago I went out to my bike and noticed it had fallen (or more likely was pushed) and it landed in a way that severed the wire to my rear left indicator. I've ordered new ones and I took the wire out completely. Being impatient I rode the bike since at night so had my lights on but the battery drained completely within about an hour or so. Is it possible that not having the indicator connected is some how draining the battery or do I just need a new one? My bike is an 11 plate AJS 125 eco2. Please don't laugh. I'm not sure if this is in the the spirit of this forum so if I've broken any rules please let me know.
