the biatch of it is, that they are all in house readily available parts.... Blast doesnt need a reengineering to be a beast... just put on the other side of the assembly line with the XB's  Great job, I am betting it comes in around the 340 lb mark... keep us posted. | ||

well the motor weighed in at 150.5 pounds on a freight scale with no oil at all. so add the gas , frame battery etc. I will have to get it weighed dry and wet once all the parts are together. | ||

hmm thats neat. so did you have to do any fabrication to get it to bolt on to the xb frame (ie special mounts of anykind). this idea had ran threw my mind before because i noticed that the blast engine looks alot like a xb engine just without the rear cylinder. | ||
| Sub65chris |
  tis is the carb in teh stock position , not going to work. | ||
| Sub65chris |
also not going to work  this is the manifold reversed. it might work if I cut the cross beams off. not my first choice I may have to make a manifold. | ||
| Sub65chris |
Firebolt020283- the first few pics were of the front isolator that i had to modify. the pics are pretty good at showing what i had to do. not a whole lot! | ||

Chris - if you run a stack and a bootie filter like EZ does, you won't need an airfilter and can run the carb EITHER of those ways. Check out the thumper forum for EZs discussion of his filter (or better said - the lack thereof.) | ||
| Naustin |
Alos, you could fiberglass a still air enclosure in the space behind the front cylinder and use a flat rectangular filter from a car on the bottom or one of the sides of the enclosure. Use the whole empty space as an airbox. | ||
| Ezblast |
Actually I was planning to use the airbox for all the electronics - including the battery, and run with the stack/filter combo which looks like it will fit - one of the two ways - the reversed looks more promising. Sweet job! EZ | ||

Obviously the intake extends to atleast the red line as shown why not break out the hacksaw/chopsaw/sawzall..etc and cut it to somewhere about where the blue line indicates A/F ratio might be off my a smidge at most but then thats the beauty of using a carbuerator! its manually adjustable. No messing with the electrics!  | ||
| Sub65chris |
 I think with one of the disk style foam filters this will work. but 100 dollars is a bit much. I may get some aluminum plate and drill my own plates and sandwich a section of dirt bike filter between them for hte reverse option. Ferrisbuellersdayoff - the problem is that there is a lip that hooks the boot i guess for better seal. | ||
| Ferrisbuellersdayoff |
Sub65 this "lip" is there incase the bike hits a bump and the impact doesnt jar the weight of the carb and filter assembly to fall off. If you have a TIG Welderor can find someone who has one as them to put a thick bead around the intake to recreate that lip. Itshouldn't be more than $20 or a 6 pack for the welder to do that for you. hell if your brave enough you can prolly do it with some flux and a soldering iron. | ||
| Ezblast |
It looks to me like it would work reversed - no cutting involved - just add stack and filter - I'll measure the distance of the stack and filter to see if its doable - if you have close to 2 inches of clearance there then you would be golden and it would fit! EZ | ||

Aha why didn't I think of this before! Get out your rasp or file, after you make your chop on the intake. File a notch into the metal about 1/8" deep. then take some 8 AWG copper and using some pliers bend it into a ring roughly a little smaller than the circumfrence of the perimeter notch. And place the ring around the intake, and slide it into the groove. being slightly smaller than the intake and notch it should be kinda tight. this will keep the ring from falling off. VOILA! Theres your lip!  | ||
| Ferrisbuellersdayoff |
BTW use solid copper, not stranded, easily purchased at your local hardware store. | ||

This is going to be a very long thread, and one that gets watched a lot. Nice job!! Cudos for having the cojones to go ahead and actually do it. | ||
| Tq_freak |
Ferris- What about a big O-ring instead of the copper lip. Same idea and might stay in place a little better. | ||
| Djkaplan |
This is going to be a very long thread, and one that gets watched a lot. I don't have an XB or a Blast and I'm glued to the terminal. It would be interesting to compare the weight of the XBlast to a stock Blast when this gets done. | ||
| Djkaplan |
How about a heavily modified XB manifold running a downdraft carb? Then you could use the airbox. | ||
| Spike |
If you're able to use a modified XB manifold, why not just use the stock XB fuel injection and ECMspy to turn off the rear cylinder? Since you already have the XB platform it seems like the bulk of the FI parts are in place. | ||
| Tq_freak |
How about a heavily modified XB manifold running a downdraft carb? Then you could use the airbox. I know a down draft has been tried on a standard XB and I dont think you could find one that would keep up with the required CFM of the 9/12 motor. But it would be interesting to see if it would work in the 5 motor. | ||
| Ferrisbuellersdayoff |
Why not? I just thought maybe a harder substance would withstand time better than a rubber O-ring. That and an O-ring might roll off easier than a piece of metal. | ||
| Tq_freak |
ok, I can see your point.  | ||
| Xl1200r |
Why not just run it on water? All the guys in quick board say you can. | ||
| Tq_freak |
On the ride home from work I thought of another point. How are you going to get fuel to the carb? I dont think it will gravity feed to well from the end of the frame horn and if you use the pump you'll need to regulate it down for the carb. Hmmm...... | ||
| Ezblast |
Small in line adjustable fuel pump such as they make for cars, go-carts, etc. EZ | ||
| Ironhead1977 |
Use a vacuum actuated fuel pump that is used on lawn equipment. If you want one, pm me and I will donate one to the project. | ||
| Luckyduck |
Maybe the popularity of this will help get us the XB6 all fuel injected and ready to ride from the factory. Wouldn't that be a nice bridge between the Blast and an XB9? Plus a great sport bike for $4 or $5 gas. Paul | ||

Im just wondering what brought you to do this. I know why I like it but Im interested in knowing why your doing it. Also wondering if you had 2 parts bikes, or 2 whole bikes.... BTW, heep those pics coming. |
