Using the gasket provided - it does bolt up and if you do the modification shown - you should have no jetting problems and be able to leave it where you put it for your exhaust. Jetting problems occur on unmodified Force units and then you'd need a dyno. The hoses in your air box all route to to your breather and can be simplified and rerouted to a crankcase type breather/filter alone or in conjunction with a 'spit can' to catch breather spew. The Force unit I origionally bought for my bike(went to a stack instead;0) gave the Force unit to the service mngr. at Hall's HD - Chico as a tip for a job well done along w/ a few other goodies)I got from Banke - our good sponsors also sell them - had a breather filter and clamps as part of the whole package. Once you grind out that vent area - your set - it all just bolts on - its the carb bracing thats the tricky part & home fabrication time though - I'll run a list of different ways its been done w/ a few pics tonight.

EZ, I can't thank you enough for all the info/advice. This whole thing is simply a vision dancing around my head right now, I still need to get the bike out of the garage @ the farm so I can see what needs to be done. A few more paychecks to pad the checking account wouldn't hurt either. =P I look forward to the pics. | ||

Pictures of intake suport mountings - note on my own: the bracket to the intake manifold is now low carbon hi tensil steel with a 1/4" rubber grommet between the the carb mounting and the bracket - the mounting points are still the same though. Also per Ray and Nallins sugestion - I have springs mounted to each side of the carb to the last head fin on each side - to help keep a constant equal pressure on the boot.     edited by ezblast on June 23, 2003 | ||

    as you can see the mounting varies wih each bike (that is why I eagerly await the Factory's hi-po option - to see where their mounting points are) and I'm sure each has reasons at least as good as mine for their choosing. Got Thump?! Just Blasting on the Dark side! EZ | ||

Gah! A possible factory airbox upgrade is going to be available? Y'know, being out of the loop for so long has really got me playing catch-up. New question (surprise!): For all you techies, how weak a link would the stock carb be once a Blast has been Nallinized? Just for S&G's, we'll say the full ($2000) 515cc big bore bolt on kit is being used. | ||
| Ezblast |
Basically what I have except the head work was local and more in line with a stage one head than a stage three, and I went with the milder andrew b-50/HD hi-po cam for less valvetrain stress at high rev.s. Nallin would sugest going with the Mikuni 42 for those last few ponies and I've been looking hard at the Eldebrock Quicksilver double pumper they just came out with a few years ago. But overall the carbs not really a week link at all - the week link would be the rubber intake boot - Got Thump?! Just Blasting on the Dark side! EZ | ||

All, EZ's pics above #5 & #6 are of Aikigecko's Blast, The intake modification is my design that he got from the archives on this board. It works fairly well and is cheaper than the Force, but requires some elbow grease and time to make pretty. Pic #8 is not a CV, it is a Mikuni 42 which is what I'm currently running on my Blast. Just thought a little clarification was in order. Sorry EZ. Ray | ||
| Ezblast |
No problem - the pics aren't to display the intakes so much as to display the differing carb bracing that must happen when the airbox goes byebye;0) - yup - knew all that - all my pics have titles at home - the hard part with over 5000 pics of buells - especially Blasts - is finding the one I want;0) Got Thump?!

Another question (got a million!) for anyone who'd care to answer: The K&N air filter for the Blast, part #BU-5000? I can't find a picture of this anywhere. Is it the filtering unit only, with perhaps a better material than came in the stock unit? Or does this replace that whole "molded in color" tupperware housing? Am I better off playing McGyver (like I see most of you tuners have done) and fashioning a new unit out of everyday household items? With a couple empty whiskey bottles, two dead monkeys, and some paperclips, apprently I can build just about anything. If that K&N part number is the replacement filtering material only, it seems rather on the pricey side, eh? I did find the recommendations EZ made about "opening up the airbox" by cutting off the air intake venturi down to the filter mount and I'll take a look at that, once the ice melts off my bike. | ||
| Ezblast |
The air box mods and the superior K&N filter should put you to 90% of stack efficiency - read free breathing - I was so suprised at that, however if you really want to change change out the whole thing for that 10% Id wait for the factory to come out with their hi-po air intake - should happen any month now - lol - Things to take note of: 1) Did they upgrade the rubber intake boot and clamps. 2) What carb support mounting did they use? 3) What are the improvements over stock are they claiming for their unit? It's not that I'm going to run out and switch from my stack - not! but if any of the mounting points are usable adaptable - I'd probably use them, same if they had an upgraded intake boot/clamp. See where I'm going - never use an educated guess when you can steal someone else's hard work and research, and make it pay off for you;0) yuppers! Got Thump?! Just Blasting on the Dark side! EZ | ||

So no one makes an intake for the Blast yet? Can anyone point me to "the airbox mods?" Thanks, Josh | ||

Thanks, I'll try the "EZ Setup", 90% efficiency should be plenty for this Blaster to get his Thumper jumpin' stumps. | ||

EZ, you care to divulge where you got a fuel enricher for the Blast's carb? Any way I can get one without getting a used carb to rip it off of? I know (I think) that the flange meets up, you just have to bore the holes out a bit, right? Thanks in advance. | ||
| Ezblast |
Didn't go there because of longevity issues with the enrichner (the plastic parts wear fast), however, Sarodude is running a Dial A Jet kit - I am thinking about going that way because it does the same thing and has no reported longevity issues. Others though have gone that route and most just got a doner cv carb from Ebay - around 25 -40 dollars - and used those parts - yes from what I've read its a pretty basic switch over - yes you do have bore the holes a little - be carefull!

Hey everyone, this link should go directly to the message that Ed referenced four posts above. Now, I've got some questions about the post. I looked into this while cleaning the air filter, and while I thought I understood the post, I'm not so sure now. Is the air intake venturi the ring of plastic that's inset from the filter mount about 1/4"? I imagine I'd get out my Dremel and remove that whole bit of plastic that's essentially making a smaller hole to breathe through. Is that right? Would it help just to remove the venturi, or is that benefit lost without going to the K&N filter? Where is the carb vent and how does turning it away from the carb help things? I see a hose going past the air intake to the carb, and there's a nozzle pointing sorta towards the opening. Is that it? What goes through the nozzle? Sorry for all the questions. If the weather was better, I'd be out riding instead.  Ok, one more and them I'm done. I found a little bit of oil in the airbox--is that normal? Thanks in advance! -Dave | ||
| Ezblast |
Ahhh - Dremel - one of my favorite tools - that is a yes to your first question - take/cut it back all the way except for that 64th - you still want to preserve filter mounting integrity. Yes that alone will help you breath better, however, the K&N is much more free flowing than the stock unit. Yes - turn the nozzle 180 - any oil spew will then hit the box wall and puddle to the bottom - not into your carb - or you could rerout the the breather out of the box altogether (same thing as you would be doing if you switched intakes anyway), yes that 'nozzle' is a vent from the engines top end and oil - if high reving, or high level - the EPA wants your engine to eat that waste product - and though its not officially bad for your engine - I just don't see a benifit - neather do most - thats what that that bit of oilly moisture is. As time allows I'll try to add stuff like that and other info as well in the catagory header - all good things in time;0) Got Thump?! Just Blasting on the Dark side! EZ | ||

EZ- The Dial-A-Jet is pretty nifty - but I'd be a touch leery of a couple of things... * Longevity? * Installation on a CV carb This is NOT a bolt on proposition! The DAJ requires a flat surface which is parallel to the carb bore. I accomplised this by building up a semi-shaped blob of JB weld and milling if flat after curing. You then need to drill / tap / install a fuel fitting into the float bowl. You also need to dril / tap the hole for the DAJ jet tube. The DAJ (and the Thunder Jet - for which service exists to install onto a CV carb!) is not a magic product like their website advertises. They almost make it sound intelligent. It's really just an additional fuel circuit that behaves differently than the main jet. It's main benefit seems to be that it somehow doesn't deliver as much fuel when it sees reversion. All it does is flatten your torque curve (helping to alleviate a reversion induced midrange richness) while giving you some external adjustability. By now should probably have figured out that the rest of your jetting will probably be different. You are adding more fuel, after all. I can't remember my current main jet size. It's 2 or 3 steps leaner than stock. I also run a 48 pilot instead of a 42 or 45. I went to the 48 because with the 45 I was never able to get the idle mix too rich. With the 48 I get the over rich RPM drop. It just seems to provide a more appropriate range for my setup. In any case, I need to get it to a dyno with a sniffer to get things fully ironed out. If you decide on a DAJ let me know. I'll tell you what to ask for when you order it. The stuff Mr. DAJ gives you isn't 100% right for the Blast. You need to custom order a kit. -Saro | ||

Finished a talk with Nallin about my dyno run - my AF peaked at 14.15 between 2 and 3 Grand and then plummited to an almost impossible 8 flat lined - he said its a wonder it running (till I reminded him of the plug he recomended - Iridium)- to drop the main down to 165 - explaining - how I understood it - that the larger compression actually had the engine demanding less fuel - not more? and that the pilot 45 was borderline lean - but safe enough to leave if I get everything else dialed in. So Blake - should I up my pilot or leave it is my question? Hi guys - got the answer off site from Blake - bless his heart - I'll leave as is -tomorrow another dyno run - if it works out well the next ones will be when I switch out to the Suppertrapp universal 3" w/17 to 21 discs - lol - Got Thump?!

Thanks, Ed! Now I just have to decide whether to start hacking now, or to wait until the warranty is up... hmmmmmm..... | ||

    Okay, here's the pictures I promised of the Blast at the dealership where I purchased mine. He let me ride his bike today. Gotta tell ya, love the VH pipes on there and the Force filter, definitely better than my Blast. When I initially bought mine I had a few prob's, aww read my profile, betcha can guess the problem. Anyway, I found out today they had adjusted my auto-enrichener when I initially had the problems, end result, quote from the mech, "your bike definetly is running better than the other stock Blast's, more torque," but possibly the reason I'm only getting 90-95 before switching to reserve. Just hope I don't have any problems because of that. No he doesn't have his filter braced, said he has never had any problems, also said he's put over 5,000 miles with it on there like that. Just in case you are wondering what is different about his carb. Owner built the Thunder Jet Kit for his bike, said it would cost me $275 with a trade in. Anyone else seen anything like this. Again, I'm new to working on and understanding the mech's of a bike. This setup adds a third jet to the bike. | ||

I like my stack better ;0) I guess if you tighten the shit out of the clamps, hug it with your knee, replace the rubber coupling with the oil, and install a dial a jet like he did to protect from a lean condition it could work without a brace - but I'd at least put the short one on like I have so that if the carb does try to go south the brace would keep it suspended in place (almost/more or less type of thing) beats a crack going all around the rubber intake boot - ripping in two and your nice Force unit and carb go bouncing along the road beside you. That rubber boot is not to be trusted and has been the woe of many a Blast - your friend should count himself lucky - strait up! Got Thump?! Just Blasting on the Dark side! EZ | ||

Ez, how is the Dayco hose working out for you. | ||
| Ezblast |
Its not - going to try plan b which is more pricy yet - Having something specifically made in simular fashion but heavier duty material and perhaps adding a fuel proof rubber inner linner to materials that wouldn't regularly be used for fuel but would have the sought after characteristics. - so the anty just went up from 60 to wow am I crazy? time - lol - we'll see - its a major search for me because its the only clear week link in the whole set up - right now I'm changing them out with my oil changes - making it part of routine maintenance;0) - this board will be first to know if something works. Got Thump?! Just Blasting on the Dark side! EZ | ||
| Spooky |
Ez, what kind of problem are you having | ||
| Ezblast |
None now - but a hot plug and cracked intake boot equalled - rebuild. I want the next rebuild to be planned - you know;0) I wasn't going to rebuild for another couple years - my bikes really only half finished in my eye and there are other things now on hold that I wanted to do to the bike before the rebuild - so when I head to the Buell Anniversery Bash you'll only see a half finished bike - still to go - suspension, carb switch, digital gauge - tach, powdercoating, etc. - just a lot of stuff now on hold this year because the rebuild took the priority instead.

I took the stock carb out of my 01 and put in a "new" stock carb off of a 97 Fat boy. Bypassing that pos auto choke was nothing to worry about, I just have to hold the throttle on for about a minute and a half on cold start until I find a choker for it. I installed 45/155 jets in it and I do notice an increased acceleration with the accelerator pump. The only thing is, when I go to blip the throttle coming to a stop sign, it POPs, and smoke is visible from the pipe. I have learned no to do that anymore, and I always have to roll on slowly in low to mid rpms. i notice the biggest gain in the 65 - 75 jump. great for passes. DOES ANYONE KNOW OF A WAY TO TONE DOWN A STOCK HARLEY ACCELERATOR PUMP? It's not as fun when I can't intimidate with throttle blips, but I wouldn't go back to the old carb just for that! | ||
| Ezblast |
Go to 165 jetting - sounds like your too lean. Throw it on a dyno that will tell for sure - but the poping / stutering is usually a sign of leanness - if you let off full throttle do you get a surge? That would be leaness. Got Thump?! Just Blasting on the Dark side! EZ |
