    So here is the blast that we will be using the cases from:


    and the XB frame(swingarm not pictured):


    The blast being stripped down:


    Test fitting the swing arm:


    Thanks to Bossanova for the wheels and squidbuellie for many of the other parts, aaron914 for the primary cover and a backup ecm. I will be putting the new primary cover on today, and then srat tearing the motor down when I get all the parts in.

    I will update the further along I get.

    A blast is actually 492, it is an xb9 engine with just on cylinder. The bore and stroke are the exact same. And xb9 is 984cc and is called a 9 so I figure xb4 was fitting. Although this blast engine is not being left stock as the only thing that will be used is the engine cases. I can't wait to get it done. Hopefully within a moth it will be done.

    So far I have the primary cover on, swing arm on, once I have all engine parts that will go on. I ordered new fittings for the oil line so I can hook them up. If I can find an xb9 piston to use, I will be putting a big bore kit in this bad boy. From what I can tell so far, this bike will be lighter than a stock blast and have more power even without the big bore kit. This blast engine is easy to pick up on my own.

    Haha, I meant if I can't find a piston I will do a big bore. Lol the only way to buy a new piston is to buy a cylinder and piston together which is about $230 plus the gaskets and rings or a big bore kit with everything for like $350.
