Came up with the idea when the warrior engine was broken down for one of the hundred times, had it for about 4 years and it ran about 2 of those. So I was going to replace it with just a big bore quad engine (ie raptor or predator etc), but those are over a grand to buy on ebay, and happened to come across some bike engines for sub $1000, some well under 1000, and I figured it couldnt be too hard to make it work.
The engine fit in the frame without even touching it at first, which was pretty amazing. Problem was for me to hang the engine on the swingarm bolt (which is how it works on the bike) I had to build a custom swingarm like you can notice in the last two pics. Those front engine mounts were also a pain, took about a day a piece.
The oilpan was also a major problem, in the videos I hadnt modified it yet, and came down from a small wheelie and cranked the pan, luckily didnt break it. Was just going to cut 3" off it, but the sump at that point wouldve been sitting in there on an angle, so I had to widen the pan about 1.5" at that point so I could just bring the sump straight down.
All in all it hasnt been too bad, just a lot of minor things that had to get modified, ie rear brake master/pedal, fuel tank, shifter, airbox.
Ive been working on it in school for about 3 weeks total, at about 6hrs total a day, so if I was able to work on it nonstop for 8 hours a day I wouldve only taken ~2weeks. And the best part is, it has probably cost me less than $2000 to make the engine work, I have however spent more than that on stuff like shocks and new bearings everywhere, etc.
Ill have it done this week though, and hopefully the elkas will get here this week so Ill get some better videos up for ya, those kindof sucked, and I never even went past 12k and never made it out of 2nd gear.
Sounds like that thing will put you on your ass in a heartbeat!
