The XB4R build begins...

[buellxb9rs]

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.

good luck!! cant wait to see what it will look like when its done!! btw, why is it a xb4r? the blast is a 500 so shouldnt it be a xb5r lol?

 

[buellxb9rs]

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.

 

[BuellRiderX]

Definitely keeping an eye on this build.

 

[GAXB9R]

First thought that came to me when I saw the title was inline 4 in a buell. XB4R

XB4.5RR [up]

 

[blacksmith]

Cool. Looking forward to seeing the finished product.

 

[buellxb9rs]

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.

 

[GAXB9R]

You gonna give the piston back after your done with it?? props for the build[up]

 

[buellxb9rs]

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.

 

[GAXB9R]

Squidbuellie didn't have one? Check with buellster parts over on the right side of the page. He carries used parts.

 

[buellxb9rs]

No, but he is checking to see if he can find one. Buellsterparts didn't have any that I saw. They said unless the motor is bad they don't part it out

 

[Daali]

Dude ,that is bad ass! Can't wait to see her done

 

[Bossanova]

That is gonna look pretty cool. Good luck with the build!

 

[Red93stang]

I have always wonder why more blast guys don't do this. Looking forward to seeing this build.

 

[buellxb9rs]

That bike you pictured has the 515cc big bore and is carb. If I end up doing a big bore I will get the 1050cc kit for the xb9 but either way mine will be efi and I will be putting an O2 in the header so it should be a breeze to tune.

 

[loose1]

Been there, done that. The efi is real easy to tune. A stock 9 map is a real good starting point.

 

[iman501]

Loose1 I remember seeing your bike at homecoming a few years back!, it's by far the coolest blast I've seen in person do far!

 

[buellxb9rs]

Looks like I'm ordering a new piston and rings, found them from a dealer for $100 together

You do realize that a Blast 515 kit is half of the XB9 1050 kit, right?

Look them up, both are a 3-9/16" bore.
