Was driving along, getting on it a little bit maybe 75% throttle, and then it just cuts out with a nice little backfire (I'm assuming from it having cut out at like 4 grand) and then that was it. Tried to go and put some gas in it thinking the gauge might be wrong, but it just turns over. Didn't sound mechanical like I snapped the chain or dropped a rod or anything.

At this point I don't have any ideas. Where do I start?
