I've got the carb apart on my WR400 and noticed a white-ish gray paste (or maybe some kind of grease) coming out around the throttle shaft where it goes through the carb body and into the TPS sensor. I don't know if this paste is some kind of lubricant for the throttle shaft, or for something inside the TPS. Anybody know what this paste is for? Anybody find the same stuff in their carb? Carb cleaner doesn't even disolve this stuff. I don't know if I should remove the TPS or not. Hate to move it from its factory setting. I just don't want any of this paste clogging up my jets! Any ideas???
