Where is winter?

December 14th and I was just outside,  6am, in a t-shirt!  Rainy but 61 degrees!  Figures, have the Arctic Cat done and no snow!

Carb motor to efi summary

Brief background: original 1998 Arctic Cat Zr 600 efi motor blew mag side bearings and took lower end with it. Bought a supposedly 98 efi motor from a dealer that only had 1k miles on it. Turns out it was a carb motor. Here is what I had to do to make it work as an efi.

1. Remove impulse line and fitting from crankcase. Replace with plug bolt and washer from dealer.

2. Remove carb boots and replace with throttle body boots.

3. Replace cylinder head with one from efi because an efi motor has a coolant hose that runs from the throttle body to the head, carbs do not.

4. Replace carb stator with efi stator.

That's it, in a nutshell. In my case it helped I still had most of my efi parts needed.

Fuel mix

I should mention that since there was oil pump work performed I mixed up a couple of gallons of 50:1 mix to run on. I'd the oil tank level goes down then I should be good to go after that
