I am beyond frustrated with the 470 I built. I cannot get the damn thing to crank over. I built it exactly as Eddie specs, but apparently my bike is just saying f-you and no matter what I do with the starter and hooking even my truck directly up to it, it won't turn past TDC. I am likely not interested in a straight up trade because of the money I have invested in it, but I promise I will give a good deal. The build is fine, the engine spins by hand, with the decompressor activated it will even fire! Screw this thing, I just want to ride my damn bike. If you have a modified stock stroke Z engine (preferably DRZ E) send me a PM and I will see what I am willing to do. Obviously I will not guarantee your starter can turn it over either, but maybe you want to try your luck on what will be a badass engine when it actually starts.
