Just curious since I locked up the FL350. I was noticing some of the newer sled motor (( Internal Combustion Engine ? )) twins on ebay. Any more modern ones that might work. I am not quite the motor (( Internal Combustion Engine ? )) builder as you.

440 needs dialed in more, more tuning, I need to raise the Engine RPM by 800-900 RPM
and need to lean out the jetting some and a few more other things, I hope to get everything
closer on the next trip to the dunes.

A Engine conversion takes a lot of work, everything is affected, you have to make
changes everything not just the Engine mounts it also lowers the resale value of
your machine (not a concern of mine) I can at any time conver back to my Honda
Engine, all my 440 conversion changes are bolt in.

Here is one already done http://cgi.ebay.com/ebaymotors/ws/eBayI ... rd=1&item=

Might be cheaper to buy one already converted?

Update, I have my other Engine ready to install and test I will finish installing and testing the
new mods http://pilotodyssey.com/PO/viewtopic.php?t=1227 soon I hope, the current
Engine has proven itself so will be sealed up and saved for a spare.

I finially got around to doing the Engine swap, I decided to put more hours on
it to ensure everything was ok so left it in for the Killpecker Dunes trip

Below is just some pics of my removed Engine.

Spooge leaking from the cylinder that had a intermittent spark problem
I need to get better spark plug boots guess I need to buy OEM Rotax
caps.

On the last trip my Engine was really rich at 7000-8000' elevation
I adjusted the oil ratio to 28:1 to try and lean it out more, it didnt
help much...

A top view if you havent already seen this view before, nice little package with that
watercraft manifold and carb.

bigpeterhead I need info on that choke plate mod and the primer setup...

I need to cover that hole on the bottom to keep the sand out,
I got sand in my recoil and it was trying to stick like a comet
or cat clutch :- )
