Re: ABS PUMP Dilemma
I also have a 2000 Lt, and several years ago, I had the same issue. There are several things you can do to try to correct the problem short of replacing the ABS unit. First and foremost is the battery. If your battery is old and weak, even if you keep it on a Battery Tender all the time, it will cause an ABS fault. So one of the first things to do is check the battery. Secondly, when is the last time you flushed the brake fluids? I believe for the pre 2004 LT's, they recommend the fluids be flushed annually. Even if you don't ride much, the brake fluid gets very dirty and will absorb moisture and other contaminants. Third, you need to make sure there is sufficient brake fluid in the reservoirs, including the rear one. There is a rear reservoir on the right side sort of underneath the seat. Also, make sure the ABS sensors have the correct gap and are clean. The 2000 LT system will not reset itself, and therefore once you do these things, you will need to either find someone with a GS 911 to reset the defaults, or you will need to take it to a dealer and have them run it to clear the faults.
On my bike, all of these things did not correct the problem. I was lucky enough to find a used ABS unit on Ebay for $400, and a friend of mine and I changed it out one weekend. It has worked perfect since.
A couple of other points. The pre 2004 LT's are not servo assist systems, and they are much less complicated to work on. I am told there are a few places that can rebuild these units. I am not aware of any places that successfully rebuild the Servo units in the newer LT's. The good news it that unlike the Servo system in the newer LT's, the braking system still works great with the ABS pump not working. You just won't have anti lock brakes that are functional. If your ABS goes out on the Servo units, it isn't safe to ride the bike until it is fixed, or bypassed. Good luck.
