    Okay, it's been awhile guys. A small update right now. Bike is wired, went to start engine fuel pump made a crazy noise, bike turned over, made a loud bang and I smelled something burning. I found the the problem is in the wiring harness. Sometimes the pump will come on, if not you can wiggle the pumps wires at the harness an it will work till you try to crank it... Ugh... No time to pull the harness and find the problem...

    Did you change out the blast cam timing cup for a xb one?

    I hate to be "that guy", but why? This looks like a ton of work to build a bike way slower than even an XB.. which is already somewhat sluggish compared to normal standards nowdays.

    It IS ****in' cool, but what do you have in mind? Max MPG?

    I changed out to an xb cup and cam sensor.

    And in response to fireinxb: this bike will have more power than a standar blast, look better, weight less, handle better and can easily be upgraded to a big bore and or turbo of I wanted. It's not that I don't have an xb already but this is nicer than a blast.

    Blast doesn't need an oil cooler - especially with a half quart extra capacity - a waste of weight - ditch it - lol

    put the turbo right where the other cylinder would have been. Looks cool Man!! I always wonder how much fab/modification it would take to put a blast motor into an xb chassis. It seems for the most part it bolts right up! I dig it!

    I'm still tracking down a wiring harness short. The pump will sometimes come on if you wiggle the wires. I'm about to just buy yet another harness.

    This reminds me of the Ducati a guy turned from a v-twin to a single an put the turbo where the back cylinder was an it made more power that before with 2 cylinders.

    So did you put your blast engine into the xb9 or did you fit the headlight on your blast? Because I would really want to know if it is possible to fit a headlights fairing from an firebolt, lighteningbolt, or just somethin better looking. And if it is would like to know how to do it

    Very cool build, I just skimmed through this thread.

    Gotta ask though.....if you're going to build a xb chassis why not use the big engine and get more power? 1 cylinder can't weigh THAT much can it?

    JMO without really doing a lot of research on this...
