I may be willing to trade my F4i full swap with water temp sensor, mount, and all..........plug and play for your 919. IF, you send me your gauges('04+ since mine is an '05 and the pre-04 won't work), 10,500 miles or less and $150 in trade. Let me know.
Well look at it this way, you built the bike to ride up to Indy for MotoGP, it became locally famous, and now having fulfilled its special purpose it's being transformed back into a merely mortal machine.
you can make the gauges work on 02/03 bikes, but you do have to chop up the connectors (or locate a gauge side replacement plug) "moding" the plug is just a matter of using a single tool (toothpick would probably work) a little bit of patience, and knowing which wires go where in the plug! You may (or may not) have an extra wire left over when it is all said and done. I believe 04+ removed a redundant ground from the setup, but don't quote me on that! Its been well over a year since I've looked at the difference between the two.
If you have '04+ gauges and $50!!! We can make this trade happen. Close to 10k miles preferred. Let me know. Price lowered as I have an elderly gentlemen interested in the bike and I'm thinking he'd like it close to stock.
