I have a 2000 , 1100 Vstar, riding it today around town. Made several stops. Noticed as I started it it was getting weaker, not turning over quickly.Eventually stalled and would not restart. The last time I drove it at night I noticed the headlights and dislay on gas tank fiickering almost to the point of going out completely.

Silly question, have you tried to replace the battery in the remote? Sounds like it's getting weaker and weaker. worth a shot.

Buy a cheap code reader ($20) and check your codes or go to your local parts place and some will read your codes for you for free.A blinking "check engine light" is a severe warning and the codes should be checked NOW.

to start with does turning the od button on allow it to start
if it does leave it at that because it will not get to over drive unless throttle settings and road speed are right
the problem with used cars is that previous owners change things and don't pass on the changes so it may have been tampered with
you could always take it to an accredited auto electrician to have the circuit checked out for changes

Sounds like a vacuums leak.
try spraying some QUICK START around the vacuums lines and anywhere else air can leak into the induction system.

Oil "use" on engines can vary widely, depending on the engine design and the conditions under which the motor has been run. VW, for example, considers 1 liter of oil consumption per 1600 km to be perfectly acceptable performance in its automotive engines--much to the chagrin of many car owners, who are used to motors that don't consume oil at even half that rate. In addition, sustained high-speed driving / riding will also tend to consume more oil, mostly because oil vapor is sucked into the engine as part of the emissions system.
After a long (300 km or more) highway run with my old XZ-550, I was always down about half a liter. I could ride much further than that around town and in low-speed riding without consuming any noticeable amount of oil, even when I started using synthetic oil, which had a tendency to leak past some of the motor's gaskets.
I would double-check with other V-Star owners, but I am personally not alarmed at the oil consumption that you have described, even with a relatively new, probably low-mileage motorcycle.

kinda sounds like a lifter

sounds like water from ethonal in gas or trash try to find some stabil ethonal treatment and run it in every tank but first try to turn your gas on and drain your carb bowls with the screww on the very bottom of the carbs drain into glaas to see if there is any water or trash or to see if you are getting fuel let me know

when i used too work on them some owner did away with the air system and went too a heavy duty shock instead might be worth looking into too save some cash or even an after market air shock

most of the time when that happens it's the dryer motor getting weaker and weaker until one day it just stops and then all you will get when you push the start button is a buzzing sound,i see this all the time on kenmore"s-mike

sounds like worn out starter brushes, remove starter and check, it sounds worn out
