Hi Guys,

I can't seem to unplug the TPS switch, it's got an accumulation of grit from the last 28 years I think. The lugs won't depress due to the latter... I need to adjust my power valves...any tips? Thanks guys

You can adjust the R/C v/vs without disconnecting the TPS http://www.nsr250.net/forums/viewtopic.php?t=11226&highlight=rpm

I had this issue the first time too. But basically you pull the center tab up and carefully wiggle the plug out. I've found that putting on a pair of thick latex gloves helps tremendously with the grip.

Just keep repeating the process carefully until it comes free.
