In addition to to that engine work, it has T5s, ported cages, matched case, coolhead w/ special cut noss 21cc domes, lightened flywheel, timing advance, and little 28mm mikunis. I also got RZ shift forks and drum and cut tranny gears along with a modded shift star...its gonna rip

I've got a crazy engine in my snowmobile, lol :lol: . It's an old arctic cat 500 and the left cylinder was bad, so I cut the cooling fins off the side of a good right cylinder and bolted it on the left side. The funny part, is that both cylinders are from different model and year motors, porting is totally different, and one has a port job done to it. the other is stock, but has extra ports that the other one don't.

I had to make spacers for the exaust, and carbs, and I used pistons out of 2 other burned up motors, as well as the rings and gaskets. :D

That thing runs awsome! It always starts on 1-2 pulls, no matter how long it's been sitting, does 100+ mph, and when it gets traction, it'll stand up and carry the skis over 300 feet.

It's going on it's 5th season, and I have $1.65 into it. B)
