    Well not that there seems to be any intrest in this conversion. I'm back to waiting for parts. I could not get it running. As it turns out the flywheel/stator that was sent was incorrect therefore it firing wayyy late. Shoukd be food to go mid next week. So I made a bracket for the wideband today. I'm using the mirror mount on the magura clutch.

    Wow have I missed that ever so distinctive whistle of an fcr. Yesterday I received the final parts. She fired to life almost instantly. I still have some fine tuning to do with the jetting, but boy am I happy with the results. My biggest observation was the better low end torque, consistency of the throttle inputs. It fires as soon as you touch the button. I don't think the motor makes a full revolution before starting. The power is wonderful from the bottom to the top with zero issues. No flat spots, stumbles or anything of the sort. I am getting the infamous smr pop on decel, but like stated I will work that out. I am 100% pleased with the results and happy I did it. The night and day difference between the EFI and carb is unbelievable. You don't notice how bad the EFI is until you ride a carbed. I have always loved huskys and always will, but boy did they miss the mark on the EFI. I will update the parts list required for the swap as soon as I can. Sometimes my friends simplicity is flat out better than half ass technology. The fcr is flat out an better system. Sure it cost me alot to swap it all over, but the end result was worth it. Like stated many times before.... There is good reason that the 450-530RR has a fcr on it. If anyone has any questions please feel free to ask. I will be more than happy to help. I sure did hit some bumps along the way, but hey that's part of the game. Aloha

    Quick little fuel economy update. With the EFI I was getting around 45 miles when the light comes on. I have no idea how much is on reserve but it isn't much.

    I'm using an RR fuel petcock so there is no reserve. Filled it with 1.9 gallons and went 90.6 miles before coming to a stop. Yes 90.6

    Did you run out of fuel at 90.6 or did you stop to fill up
    My 2010 SMR runs out at 67 miles you are pushen

    That running out had a bottle in my backpack. Tell me that isn't more efficient. And I haven't tuned it yet. 

    Thanks to tech for making a plug and play harness for my lc1 I highly recommend it. I was geting some popping and as it turns out it was a rich and lean pop. Way rich on the bottom and way lean on the top. I got it almost dialed in. Jyst gotta go up one more on the main. Current settings are 40 pilot, 1.25 on the fuel screw, clip3rd, 185 main. Like stated I gotta go up one more on the main, a 185 is already big in my mind, however the lc1 doesn't lie.

    Well I'm still getting it dialed in. At this point I'm chasing numbers sort of speak. I'm close but close isn't good enough. Lol i wonder how far off it will be when I change it from a 450 to a 530 in a few months.

    Well I'm all dialed in.
    Q needle clip 4.5
    42 pilot
    182 main
    Saj 80
    Maj 200
    Fuel screw 1/4 out (got a issue here)
    Leak jet 60 but am playing with these

    I think I have the notorious popping on decel on the huskys figured out. The problem lies in the saj. They go lean off throttle but the stock 100 jet jyst let's too much air in. Drop it a size and it goes away

    Nice write up and nice work, got to agree with you on the EFI, it's just not as good as a decent carb, I think more would follow you if it weren't for the expense.
