  1. Tach failure, advanced course.

     

    The tach on my '97 1100 Sport-i quit, mostly suddenly. I read everything, tried the grounding and fairy dust. I learned a few things, and one relevant thing; The only thing the case ground serves is the lamp. The electronics are 100% insulated from the case. In this case, the failure is at the tiny motor coil that drives the needle spindle. Unfortunately for me, the broken lead is the one from the center coming up the side of the windings so I have no free wire to resolder to. Were it the outside lead, I could unwind one wrap and recalibrate with the pot if necessary. I suppose I could measure wire and count turns, but i just don't have that in me.

    Yet.

  2. Similar symptoms on my new-to-me '97 1100 Sport. TPS went out after 50 miles, lurching and backfiring. It quit altogether. New TPS and it's great! tune up the MyECU a bit, 'round the block twice or three, and... dead  quit with no warning. Pushed it back half a block, and after cooling a half hour it ran. Sort of. Came back cold the next day, fired like never before. Shut it before it got hot, checked the Cam sensor; .75 ohms. Ran until quit, 128*C. (quit while standing still, too) rechecked cam sensor, .08 ohms. Apparently shorts when hot. 

    Must be Italian.

  3. Just got a '97 Sport i, stock pipes and mufflers with i think a Ferracci crossover (it's cracked and repaired) 

    I'm adding a oxygen sensor bung to the crossover, but the cross and mufflers are pretty tacky looking. 

    Who still makes a good system for this thing? i'd like a X with o2 sensor so I don't have to add it, and I'd like to buy mufflers that fit rather than find something close and engineer the fit. 

    Anything still out there?
