Aaron,
Can you look at the rear isolator mounting pads on the Blast and the XB engine cases and tell us if they are the same? (you are the only one I know that would have both engine cases at hand)
Thanks,
James |

EZ,
Don't we have a topic similar to this in the thumper forum? Blast in an XB frame...
Can we move this thread over there? |

Leave it here - its the only way to get a full range of ideas! It will get moved when it becomes less topical and becomes very much historical - lol - into the proper thumper sectiion - lol - Got Thump?! Just Blasting on the Dark side! EZ |

Greg,
I've seen a couple of swingarms on ebay, but no frames.... 
I'm beginning to think that ditching the XB swingarm would be a better idea. You could make a custom swingarm with provisions for final drive ratio adjustments pretty easily(better for track days).
If the factory was going to do this, they would probably have to downgrade various chassis components. You have to figure that the target price would have to be around $2000 less than an XB9R (roughly halfway between the Blast and the XB9) I don't see how you are going to cut cost enough by just removing one cylinder.

Greg,
It's not that a smaller rear wheel and tire cannot fit in the XB swingarm. It is that a one inch thinner wheel/tire might look a bit silly mounted in a wide swing arm designed for a one inch wider wheel/tire.
I'm not grasping at straws, but thanks for trying to point out my failings; it is so very constructive of you to do so. No, I was just describing a few of the obstacles possibly confronting an adaptation of the XB9R to a commercially viable 600cc thumper version. Blindly assuming that any such obstacles will not be problematic would be a HUGE mistake. In such a serious commercial venture, each potential obstacle warrants investigation and understanding prior to locking in the basic design. That is what we have been talking about right, Buell designing and selling a commercial SuperThumper?
As to your personal project... I wish you all the best and am sure you will be successful. It will be interesting to see the progress and the result. Why not buy a used Firebolt, remove powertrain, sell the parts you don't need? Or maybe it would even be feasible to remove and cap off the rear top end assembly. Cover the hole with a see through plate, would that be cool or what... to be able to peer into the crankcase of a running engine.

Ben,
You are right. My brain is stuck in common crank pin mode. With a V-Triple you could configure the crank any way you like. It is an interesting idea. |

I don't recall if it was Medesto or Rocklin HD/Buell but one of them has a HD racer in their collection with just such a setup except the plate is not clear. Looked really weird to me. Kind of like I thought a Blast! would look when I first heard about it.

I think that the early 30.50 H-D racers were that way, and there is one LSR team (Tatro Machine) running half an Ironhead Sportster at El Mirage with a similar setup. The funky thing about the Tatro Bike is he runs the REAR cylinder.
Try to Imagine an XB9R with the front cylinder missing... that would be funky.

Feuling W-3? a 1500cc Firebolt? coool! you might need an extended front end to fit the front cylinder, how about a springer? (he ducks & runs away....)

I have complete faith in the Buell team's ability to make such a project work should they choose to create such a bike. They may not make that choice. I have said from the beginning that if they don't I am prepared to create such a bike for my personal use. I will not presume to tell Buell what is needed, financially or technically, to make such a project work. I have yet to build the prototype and they have much more experience in this area than I.

It's just a bunch of guys jawing about stuff that interests us. No one is presuming to tell Buell how to run their business. What was it you told me, something about lightening up? |

I remember back when I first heard about the Blast but hadn't known the name of it I did a search in Google for "Buell Single Cylinder Engine" or something like that. One of the pages that came up was a custom built thumper that was 800cc (I think) and it was mounted up in a S2 chasis. I always loved the way that bike looked and the idea. Can't find the page anymore.
Anyway I think the idea of a 600cc or even the 720cc Nallin Blast engines in an XB chasis is a very cool idea and you could make one hell of a bike by combining the two. More then likely one that would walk all over a stock XB if you used the 720cc engine. And hey no one has put fuel injection on a Blast yet and we don't know how that will work out yet we could end up with a few more hp or not. All depends on the the setup. But hey I would love a fuel injected 720cc blast engine in an XB frame or hell even a 250cc GP bike frame. |

We have an XB and a P3 motor sitting side by side in the shop, and that pad where the rear isolator bolts up sure looks the same to me. I didn't actually make measurements though. |

Thanks Aaron,
That's what I was hoping.
Measurements? I trust your eyecrometer!

Thanks Aaron.
Another question for you. Do you have a feel for what you think a reliable, streetable P3 engine could put out power/torque wise?
This project is looking better all the time!

Heres a thought from one of the other quick boards - the Buell 2004 - http://www.badweatherbikers.com/cgibin/discus/show.cgi?tpc=4062&post=177473#POST177473Look for RD350 's post - Now there is a pleasant thought! Got Thump?! Just Blasting on the Dark side! EZ

Greg,
Sitting and looking at both bikes side by side at the dealer, along with both parts books closeby, this looks like a really straightforward proposition. Of course then my salesman buddy had to tell me about the XB9R with a salvage title that he bought for ~2800. The bike needed a front wheel and some triple clamps, pegs, and had minor dings in the frame. So, you figure,
$ 3000 salvaged XB9R
$ 2500 Used Blast
$ 2000 Nallin Stage 3 600 kit
$-1500 Sell XB engine
Really Bitchin Bike ~$6000
Knowing you did it youself, Priceless.

In your cost breakdown, you forgot to mention the free straight jacket you'll be given in the bargain.

Here's my $.02 worth....
Put a 650cc thumper (I believe Erik has one in is garage) in the XB frame. Then replace the swing arm with something smaller & lighter. The oil reserve is then moved to the center of the bike (in the "hole" left by the missing cylinder. Maybe even mount the oil tank directly where the rear cylinder was removed.
This should vesible for around $6K (based on current Blast & XB pricing).
After 1 yr of real world, you take the 650cc and add the rear cylinder to make a 1300cc XB13R.
Seems to work to me |
