I just want to give a shout out to Dave Sprinkle who is now making brand new TPS circuit boards for the 914 FI system.
This is seriously the best $35 I've spent on the 914 in as long as I can remember. It's a simple installation with the included instructions, and only took me about 30 minutes. After this, all of the jerkiness in the acceleration was gone just like that.
A new TPS is NLA, and cost about $150+ last I checked when they were available. This $30 part restores the switch, so get one while you can.
This will certainly keep me happy with my 2.0 until I have the time and $$ to convert to a 6!
