I was finally able to find an extra wide crank kit from BikeBerry.com. It is Item# LEK_WIDECRANK and costs $49.95. Here is a little review for everybody.
General: This is a very accessible crank and bottom bracket kit. It does not require any special bike tools to be installed. All you need is a 14mm socket wrench head and a large adjustable wrench. You'll also need some bearing grease. However, if you want to remove the crank you will need a crank removal tool.
2 Stroke: Now I don't own a two stroke engine, so I can't be completely certain, but I believe this crank kit will have no problem clearing a 2 stroke engine. If it doesn't, all you have to do is bend the arms.
4 Stroke:This kit clears the right side of the engine with no problem. However, there are complications with the left (drive) side. Of this I can only speak for the 4G drive. The left crank arm that comes with this kit is too long and hits the plastic drive cover. The arm can be bent to clear it. I simply replaced this arm with shorter one that came with the original Grubee kit. It is a close fit but depending on the type of pedal this should work fine. In the end you will have pedals that sit relatively close to the engine.
Overall, I give this extra wide crank kit an A-.
