I am sorry if this has been answered a bunch of times, but what value resistor is used to mod the air sensor to richen up my Drifter? Is there a schematic or drawing with it to make sure it's done right. Many thanks to all for answering. Ride safe bro's and sisters

Sorry, don't know the resistor value but it was a common mod back in the day. I considered installing a variable resistor so that I could 'tune' things a bit - I was experiencing serious engine pinging - which I eventually traced to several faulty pins in the ECU connectors. Why are you thinking you need to 'enrichen'; are you experiencing some pinging?

I am looking at all options without going too crazy to get optimum performance, and reduce chances of pinging. The bike came with nice aftermarket exhaust, and I will be looking at a BAK or better flowing intake, so a variable resistor seems like the final option to wake it up. After some digging it seems folks have used a 1K linear pot, and put in up to 1.5K of resistance to the air temp sensor, to richen it up a tiny bit across the board. Earlier sensors were one wire, but mine has a two wire sensor. I ordered a factory service manual so I can see which wire to add resistance to. Don't want to guess. However, this is the first I have heard of the ECU connection causing pinging problems. I should probably spray that out with Deoxit, and slap some dielectric grease in it to be sure it is not a problem. It seems there are frequent complaints of 1500 Drifters pinging on here. Appreciate your advise. Thanks

I never met anyone else that had the problem before either. The ECU has mail pins while the two harness connectors have the female 'pins'. I found several of the female pins in each connector were broken right at the mouth of the 'pin' where the metal is folded over to act as a spring contact. I eventually replaced every pin on both connectors.
