I bought Hypercharger kit and adapter from American Sport Bike and they have the worst instructions this side of a chinese made product. With that said, I think I've got a handle on how it's supposed to go but there are some issues which I'm not too excited about. You'd think with paying over $300 the thing would be a direct bolt-on without any issues and with good instructions. The adapter piece is just an aluminum spacer with no real instructions and the Hypercharger instructions are terrible! So, I need someone who has definitely installed one of these on a tuber. Here are my issues and/or questions. 1. The 3 long allen bolts that hold the hypercharger to the carb appear to only have 2-3 threads left to screw into the side of the carb; this after installing the bracket on the carb, then the aluminum spacer/adapter, then the Hypercharger. Anyone else have this problem? See photo. Here is how I have it stacked, minus the bracket on the carb which I already have mounted. Can't really see but if I hold it all together snug I have 1/4 inch of threads. Add to that the width fo the carb bracket and I'm left with only a few threads [IMG]http://i32.photobucket.com/albums/d28/Schultzee/urls/hyper.jpg[/IMG] 2. You see the little rubber hoses and fittings on the end coming from that manifold thing, the very bottom piece? -I installed the little bolt fittings onto the vaccum bungs in the cylinders on each side of the carb. What's to keep me from simply utilizing the stock fittings intead of these special jobbers that came with the kit? Meaning, why can't I just cut off those special rubber fittings and hook the tubes straight to the stock fittings? 3rd. This is a pic of the back of the Hypercharger and showing the vaccum assembly or whatever it's called. -What is the single screw coming out of the middle and what does it do? -See the gap from where the plate should be screwed down flush? I tried tightening the screws to make it flush but they aren't moving too easily. I wonder if back them out and try to refit them if I will screw anything up? Is there anything underneath that cover that could get screwed up if I pop the cover off to see why it's not sitting flush?

here's first photo. No freakin idea why this website won't load some photos when i copy or put image code.  | ||

the single screw in the back adjusts the opening of the butterflies, IIRC. | ||

how long are the 3 bolts? http://www.jpcycles.com/instructions/new/400-378.p df | ||

mine doesn't use that breather spacer thing, it has a T into the alum spacer, and you just route the breather lines to it, or as i have it, plugged and the breather lines to a catch can. i think the breather/adapter/spacer thing is what is your issue here. | ||
| Michelangelo |
Yes you're correct. Talked to American Sport Bike and Al told me not to use that manifold, hose spacer looking deal. But then that brings the question: how do most route, or what do you do with the breather bolts from the cylinders? Pics would be great. | ||
| Sleez |
most people route them to a catch can. i used a manifold thing like this; http://www.debrix.com/ProductDetails.asp?ProductCo de=31-0431-VT i got mine from HD, think it was like 29.00, don't have the p/n handy, sorry. | ||

I have a Hypercharger on my S1 and do not have that breather block on my application. I am running the Force breather set up to a Pegasus Racing Catch can | ||

ok so I got the Hypercharger installed and all but I don't think the vaccum operated butterfly valve is operating correctly. Here it is, with engine NOT running. Should it be opened more than that when NOT running?   I was told it was supposed to be closed when at IDLE. Mine doesn't not close at idle, it stays the same as the above pic. Is there something wrong with my spring? I know there's the little adjuster screw on the back of the assembly. Which way should it be screwed in to adjust what? | ||

With the engine off, there is no vacuum to close the louvers so that is normal. It should however close when the engine is idling. (that's why there are slots on the back of the aircleaner. You don't want to choke it off!) Where did you hook up the vacuum line? | ||
| Michelangelo |
I hooked vaccum line to the vaccum tube on top of the carb, with other end of the T going to the little sensor (with two wires). Hooked it up according to instructions and American Sport Bike (Al) where I purchased. | ||
| Natexlh1000 |
Is there a way to reduce the force of the spring? I'm thinking that perhaps your bike just doesn't suck enough.  | ||
| Bartimus |
wow, it's hard to believe that a harley based motor doesn't suck enough... OK, all kidding aside, do the butterflies move at all when you rev up the engine? It sounds like you have it hooked up right, the little thing with the two wires is your VOES. also, I used the same kind of breather reroute that Sleez uses, i got mine from JPcycles. | ||

FYI, I Just run a tube down to the ground. It actually fits right in front of the front drive pully so it is pretty well hidden. Works good enoght for me. | ||

One other thing: I just noticed you're running BUB pipes. They used to have a bad reputation as being prone to fall off the bike. Just a heads up for ya. | ||
| Michelangelo |
My butterflies open slightly when I get on the gas but they aren't fully closed when idling, as I've understood they are supposed to. As soon as I can I'll take it back off and call their tech support. THere has to be a way to adjust them properly. Via email they told me they were set at the factory but can be adjusted by the screw in the back-only accessed by taking the whole assembly off. I've not had any problems with my Bub pipes coming loose. Sounds like someone needs to check their facts and use loctite on all their harley stuff. | ||

"I've not had any problems with my Bub pipes coming loose. Sounds like someone needs to check their facts and use loctite on all their harley stuff." Careful what you say! "Sounds like someone need to check there facts" The people here know more than you or I combined. I made the mistake of thinking that i know and knew what was really up! Don't be arrogant. I was and now i know, and now i understand. So just be a sponge if you really care and remember the info. Use it or not. Dont make negative comments.FYI! | ||
| Michelangelo |
Not being negative. Fact is, my Bub pipes have not rattled loose or "fallen off". And yes I use blue loctite on all my nuts and bolts | ||
| Natexlh1000 |
I believe the issues were not that they were loosening up and falling off but that the earlier models didn't take into account the engine flopping around on rubber mounts. They were fatiguing and popping welds. At the time, sportsters weren't rubber mounted and I think they just adapted the sportster design. It's good that they revised the design. |
