You can make the average WC-1 motor travel at 45 MPH without a lot of expense.
The cylinder can be modified to hold the valves seats in place [with set screws installed]. The head gasket can be changed to a copper version to transfer heat better.
The head can be milled .060" to increase compresiion and make bike run much better.
The camshaft can be advance one tooth to make it run leaner [too rich in stock form.
The long studs from the crankcase need to be removed and replaced with a bolt kit [have them in stock].
I wouldn't be too quick to consider anything from Joe in Tiawan as he has failed at almost every venture he has suggested [I now have a box full of his latest efforts concerning the automatic clutch and guess they will make great "boat anchors"].
Have fun,
