TPS adjustment problem
Well, I've been getting my 2003 V-Star 1100 back in riding condition. I cleaned out the carbs real well, changed the oil, took it for a few rides. At first, it went very well. Then, I started getting severe bogging with the throttle wide open, then just severe bogging or loss of power across the board. My assumption was that I screwed up something in the carbs. So I started taking them off again, and noticed that my TPS was loose. The screws had been replaced with philips head screws, so I started the adjustment process, per the service manual and many other sources.
When I adjusted the TPS to what was within the limits prescribed (my low end was about 800 ohms, and the wide-open was about 5k, but this was within the tolerance in the manual. I should note that I could not adjust (by turning clockwise on the carb) the sensor any more, so I could not get the lower bound of it below 800 ohm. If I turned it counterclockwise, the range went up outside the ok range.
But starting it again yielded similar results. Bogging under open throttle or under engine load, a smell of rich gas, etc. After a decently long ride with the "correctly" adjusted TPS, and I just made it home before the engine did what really looked like it had flooded - while riding. Rich exhaust smell, consumed a lot of gas, couldn't start again right away, but it did start the next day.
I've tried testing from the point under the seat, with the same results. I tried re-positioning the sensor to where it was physically (more towards the center of its adjustable range) to no avail.
I guess my questions are these:
1. Could my seemingly problem of running super rich (to the point of flooding while running to eventually flooding to stalling) be caused by a bad TPS or TPS misadjustment? Is running rich even my problem?
2. Do the sensors often fail like this, and is it replaceable? Or should I still be looking to the guts of my carbs for rich running? Or what other performance information can I gather to more effectively troubleshoot?
