2003 RX-1 Stumbles Off Idle

[mg_sxviper]

I was just reading this thread tonight, I am so glad you got it figured out.
by chance was the sled from Central Alberta? I seen an ad for a silver rx1 in that area back in mid to late December, advertised with this exact problem for a Good price, I half way thought about buying it but was waiting to sell my old Skidoo first, needless to say it wasnt on marketplace very long before it was sold.

No I live in Chelan, WA. It sat out in my neighbors yard for a few years and the pack rats had chewed the ECU wires and there was water in the crankcase from the upturned exhaust. I recovered the seat and it runs great now. The only bug I have is sometimes it will blow the ignition fuse when I make a slow speed hard left turn. I've been carrying a pack of fuses when I ride and will have to find the wiring issue this summer.
