Ok, you guys got me! This thread has thrown my interest into a conversion project.
Now I have several questions about it and I have 100% no knowledge on sled engines and such, so please bear with me.
1-the 583 kit Farr sells for the Pilot-does that come with carbs, I don't see it listed as such. If no carbs are supplied, do you guys use 2 carbs or purchase a 2-1 intake for the Engine. Are they even made a 2-1 intake?
2-if they do make a 2-1 intake, what carb works best? Larger, smaller? Also air boxs? Pictures of your guys current set up would be sweet indeed, especially for the back yard guy. Is there room for a box style set up using this Engine?
3-fuel-I see that the stock OEM tank will not work, as pictured above an afternarket one is the way to go, does it work off gravity to supply the Engine?
4-cooling. What type radiator have/are you guys using currently? Pictures?
5-the alignment belt wise, I see in the thread a different belt is/has been found to utilize stock pilot trans clutch. Can you guys clarify the belt maker, size please? Any issues running the SUPPLIED CLUTCH TO stock trans?
6-wire harness. Farr supplies from reading above just a secondary kill switch that is added to the OEM harness, that's all? Everything OEM in the Pilot harness is utilized for the rotax Engine? No other modifications are needed?
I am sure I will have more question. It was funny I was looking back at files I had here way back from the darkside issues. There was several fellas which tried to sell a similair kit for conversions for a ton of cash-and it never took off. Seems to me this fella Farr is really helping the community out by making this kit almost(and I am making this statement purely from reading posts here)bolt in, really seems like the kit is a win win. Kudos to him.

I talked to him today and hope to have his kit within two weeks. ill start a build post once I get it.

i bought a 670 kit (why not go big). it does come with carbs.


i still need to come up with the following parts
1. Fuel tank and roll over valve
2. radiator and fan

Emmanuel said the stock radiator and fan should actually work. I may try it and powder coat the fuel tank satin black. keep is as stock looking as possible

The pilot rad wont work. We tried on Steves Pilot and it ran really hot.

These 2-up L/C Rotax engines out of a sled will run hot on an ATV radiator. On the sled, the long finned heat exchangers are cooled by a steady supply of snow from the track. Google it. And they're generally run in the winter (when there's snow).

thanks for the input. Ill see about getting soemthing like this on order today. I wonder if i can get a cap set to relieve at the same OEM pressure of the pilot cap?

My only concern would be the fan if its automotive quality, they were using the flat style motors on some of the Briggsbuilt cars and they would last only a 1/2 season at best then take a shit, I did a CSI on one they threw in the trash and the magnets came off the housing and got all jammed up with the rotor locked it up.

I would only feel comfortable with a fan off a ATV that was made for the bumps and jumps.

I ran an 8" automotive fan for 3 seasons on my 570 odyssey with no issues. only reason I'm replacing it is because I upgraded to a larger radiator. my 670 pilot has a 10 or 12" fan with no issues so far

Go jump it 4-8 feet in the air about 250 times let it know how its working out.

sounds like a challenge?

Yeah, you need a little jump meter, like an hour meter on an Engine, to keep track.

I use a Spal fan. It is a pull model... Sits behind the radiator.... Keeps a 700 Big block twin cool for me.
