Cycle World picked the Blast as one of the most economical bikes to ride - 71plus miles to the gallon measured - anyone else get that? I've gotten about 68 as a best - still I'm curious - the write up overall wasn't bad either except for the looks being a bit dated - lol GT - JBOTDS! EZ | ||
| Naustin |
Best Mileage: 135 miles @55-60mph on 1.765 gallons = 76.5mpg | ||
| Light_keeper |
Only a rough est of 65+ .  | ||

I am assuming thats a bone stock bike? With a pro series pipe and air filter I was getting 50 mpg. But then again I'm no little guy. At 250 lbs. I don't think thats to bad. | ||
| Jugallo94 |
With my vance and hines pipe and my pro series air cleaner I weigh 230 I get about 70mpg on the freeway at 70 mph. | ||
| Ezblast |
17blast - I'd love to see pics of your bike! GT - JBOTDS! EZ | ||
| Naustin |
Ditto! How did that xb12 shock go in there? Pics of the swingarm and shock mount too!! I live in Albert Lea, Maybe I can see the bike in person some time!! | ||
| 17blast |
I'll get pictures up as soon as I'm able. And as far as the millage goes, I forgot to mention that I ride my Blast balls to the wall all the time. When I'm looking to take my time I break out the Electra Glide. | ||
| Jugallo94 |
Holy crap I just checked on getting my v&h header pipe jet hot coated and it costs almost as much as a full setup D&D exhaust will. So much for that route. | ||
| 17blast |
If any one would like, I'd be more than happy to share the drawings I have for the fork and swing arm conversions. "Beware" there is an extensive amount of machining for these conversions. | ||

Jug, I had one done by these guys. They did a nice job and it lasted as long as I had it. I plan on sending my second White Brothers header to them before I install it and my first one to them after my brother re-welds it. $35 is just too cheap for that kind of insurance (Message edited by Xgecko on January 06, 2006) | ||

Just an fyi...the American Sportbike Night website is up and running again. Thanks to Mark Howard and Jim Armstrong... Take a look at some of our old history photos and the new podcasting section. More to come. Ezblast...we need to add a blast section to the asbn web site, showing some of the blasts and some of your ride stories. If you have them, send them over to either woz or me, and we will try and get them posted on the site. http://www.americansportbikenight.com | ||
| Jugallo94 |
Thanks gecko. I am going to contact them. That price is worth sending it to them and not wasting my time again. | ||
| Ezblast |
Rex - will do, Tony - thanks for the link! GT - JBOTDS! EZ | ||
| Ezblast |
 Some one should do this with a Blast! At least the motor part! GT - JBOTDS! EZ | ||

http://www.ninja650.com/` Is this really supposed to be the new beginner bike? GT - JBOTDS! EZ | ||
| Jprovo |
Yup - That's the one. It seems that 650 Twins are considered beginner bikes now. Personally, I like some of the concepts of the bike, but the bike doesn't rub me the right way. I feel the same way about the SV650. | ||
| Jprovo |
That Single from Goldammer kicks. I wish that I had the time to build something like that.  James | ||
| Ezblast |
Yeah baby - that would be the answer to all your singles need for power - just max stroke and bore, then apply supercharger! That dude is such a craftsman! One off suspensions and engine ideas - he'd be great working for a motorcycle designer for production bikes - he's always been so creative engineering-wise in the Chopper world - picture a Blast motor did up like that in an XB chasis - drool! GT - JBOTDS! EZ | ||

It would be extremely hard to supercharge a blast. Think of all the work to rig up the pulley system. It would be simple to bolt up the compressor, but the rest would be a nightmare. (Message edited by naustin on January 09, 2006) | ||
| Ezblast |
Pully system would be easy - just a second pully to the drive belt pully and your done! Yes - I've been researching this - psi would be between 7 to 9 for a stock piston, and I've thought the tricky part would be the actual mounting of the SS and a wastegate, and setting the carb up! The drive part was easy though. GT - JBOTDS! EZ | ||
| Jprovo |
I'd drive the supercharger off the crank or cams. It would be pretty straightforward to machine up a cam cover that had a PTO for a supercharger. I don't know if you would want to run if off the drive belt pulley. You really want the supercharger speed dependent on engine speed, not rear wheel speed. | ||
| Ezblast |
OK, but why? It would only spin up when you wanted to move which is when you wanted it to spool up. Just when I thought I had it easily figured - lol GT - JBOTDS! EZ (Message edited by ezblast on January 10, 2006) | ||
| Naustin |
Well, it has to do with gearing the supercharger pulley. If you run it off the transmission sprocket, you're only going full boost at the top of 5th gear, when the transmission sprocket is turning the fastest. At the top of second gear for instance, your transmission pulley is not turning nearly as fast as it does at the top of 5th, even if the Engine RPM is the same. That's why you want the supercharger tied to the crank. Also, if you geared the supercharger pulley to produce full boost at the top of third gear, for example, then at the top of 5th gear you would be spinning the supercharger way to fast, which could cause damage or a total failure. At least, that's what seems logical to me. (edit) Of course if you did run the supercharger off the tranmission, you would get stable boost pressure increasing with speed. So, when you shift into 3rd gear, you would have more boost pressure available at the bottom of 3rd than if it were tied to the crank. But at the top of 3rd gear, you would have a lot less boost than if it were tied to the crank. You might have 0-20% across 1st gear, 20-40% across second, 40-60% across 3rd, 60-80 across 4th, and 80-100% across 5th. So going back to the third gear example. Is it better to have 40-60% boost across 3rd gear, 20-100% across the RPM range as you would get when it is tied to engine RPM? I'd rather have it tied to engine RPM I think...

Wouldn't that be what a waste gate is for? GT - JBOTDS! EZ | ||
| Naustin |
I don't know what a waste gate is for. But I do know that mechanically, there is an optimum RPM to spin the supercharger to get maximum boost pressure. You want to hit that optimum, and then there is no reason to spin it any faster. If you hit that maximum at 40 mph and it is driven off the transmission, by the time you hit 90 mph, your engine is going to be injesting shrapnal from the disintegrating blower... | ||
| Ezblast |
Lets say your SS will spin up to 30 psi safely, but you only want 9 max - the wastegate discharges the rest keeping you at a max of 9. GT - JBOTDS! EZ |
