Good God...a simple tuneup got close to 10hp... | ||

Ross: - that Hypercharger kills knee room - consider the cams decision carefully ... some folks prefer the M2 cams over the Lightning units ... not as fast but makes for a torquey powerband. - consider carefully how much or how little that ignition system brings to the party, for the money spent. The factory Buell system is pretty good. Here's some info. Good luck, AW | ||

Ross: "Hyper charger (gotta lose that ugly air box) $160 " Three things here from a HyperCharger owner: 1) It's not really $160. You will also need the $40 adapter (spacer) to fit between the engine and air filter. 2) You'll wack your knee every time you hit the brakes and that gets old in a hurry. And 3) I've been told (but I can't prove) that because the vacuume line that operates the flaps is "T" fitted into the vacuume line from the carburetor to the VOES, it disrupts the normal vacuume and causes the (vacuume operated) timing to be inaccurate. All things considered, I wouldn't buy the HyperCharger again. My boy has a little round carbon fiber K&N unit that he bought from ASB (part #5039 - $230.00) and I like it lots better. | ||

Ross, do some aircleaner research, and I'd go with a Yost power tube sofar as jet kits go, I got better throttle response, improved power throughout rpm range (especially low-mid) AND better fuel economy! Jagg's a great idea, esapecially if you ride hot weather, put a tall Dyna filter on it pronto, that helps too. If yer gonna do ign., go single fire, stock works good. I got N6 cams, some guys don't like em, but the only Buell I've had stay close straight line is a dyno tuned X1 w/pcIII, and 30# removed(lotso trick C/F parts)and I get him 1st gear everytime. plus he weighs 15# less than I do. My bike's never seen a dyno.I've also heard Mikuni is the way to go.... Ray | ||

AW: I was just reading some of your previous posts here on this page ("I've been able to get more out of the motor without the air cleaner in place. ") and it seems to me that you and I have had similar experiences with additional power when air cleaners are removed (go figure). And how much was this difference  . Maybe in July we will be able to see if the Indiana differences are similar to the Colorado #'s.  Got to run Neil S. | ||
| Aaron |
Hey Neil, You know how dyno testing is, there's basically about a 1hp repeatability. So resolving small differences accurately means I'd have to do bunches of pulls with and without the air cleaner and establish the range of results in each configuration and then I could tell you the difference with some degree of confidence. As it stands now, my best estimate is from 1 to 3hp, depending on the bike. You'll have to bring that bike over, I'm not likely to drag the dyno up to Breckenridge! I can only pull 1 trailer at a time and I think it's probably more important to bring the RR, since it IS is Team Elves event! See ya, AW | ||

WoooooHoooooo!!!!  88inches88inches88inches88inches88inches88inches Just in case any body is wondering take a look at the base of the cylinders. If you look carefully you will see AXTELL. bighairyralph | ||
| Peter |
BHR, You've probably written about it before, but did you have to bore the cases much to fit the barrels? Do you have an above pic? PPiA | ||
| Ralph |
Peter, if you look back a month or so ago I posted a picture of the cases from above after boring them out. They're bored out so far it's down right scary, but I'm not concernd at all. Axtell has been doing this for a long time. bighairyralph | ||
| Peter |
Ooh yeah! I remember seeing them. Scary is the correct word. PPiA | ||
| Ralph |
I'd a done that for ya Peter if I had half a brain. Thanks. bighairyralph | ||

hey guys Ross again here. quick question. The hyper charger i was so fond of in the ads, i am now being told throws off the timing because it uses vacuum to open the butterflys. I was also told not to get the tube and conical filter. I want to get this stuff done right after my 1000 mile service and i'm on 800 something. PLease give me some insight on what i should do with my bike. going to do carb kit, slip -on and different intake any suggestions on brand or tricks that would help in this endeavor? Rememeber i am a college student and on a VERY tight budget. Thanks ahead of time guys Ross | ||

Hmmm... let's try to post ONCE AGAIN... Ralph, congrats on your 88" project. I have 2500 miles on mine, built here in San Jose with the help and advice of Yankee Enginuity (YE). Mine has the YE 4-piece windage tray setup, S&S rods, and T-Storm heads treated to a $300 'massage' at YE. Duncan at YE said use the AAC cylinders and so I did as he directed. Buell race pipe, N4 cams, Mikuni 42 155 main needle on 2nd leanest, 2.5 by 12" glass pack ($75 installed) An S&S teardrop aircleaner has a K&N filter. On Duncan's old hydro dyno, we had to tie the rear end down and let air out of the tire to hook the thing up. 90 ft-lbs torque qt 3000 RPM 105 ft-lbs torque at 5000 RPM 120 horses from 6500 to 7000 RPM Duncan sez that the motor is 'very happy' | ||
| Ralph |
Dave, that's awesome. I'm not really expecting to see that much horse power from mine. We'll just have to wait and see. Sounds like it's very happy, surely you are as well. bighairyralph | ||

| Muell |
Hey folks....I just bought a '99 X1 with 1000 miles on it and it's bone stock. I am looking to do some performance enhancements, but want to get the most bang for the buck. Someone suggested that porting and polishing was the best way to go, but I am thinking of a pipe, new air box and dialing it in. Anyone have any suggestions? Much appreciated. | ||
| Jasonl |
Muell - sounds like you're on it. Yer planned mods and a good dyno tune will get you some more power. The injection gurus on here can tell you how best to handle that. | ||
| Bigblock |
Muell, Power Commander and a set of cams, the Redshift cams seem to get the best press, but you have to check all clearances, I am running Andrews N6's, they're bolt-in, and I LOVE-em, and everyone else I know of who has 'em, loves 'em. Now, you may hear some naysayers on this issue, but they probably got dusted by a bike that was N6 equiped, and they're just jealous. Now, if you are really serious, punch it out , port the heads and run some redshifts, get a dyno tune and we'll all be jealous! | ||
| Leeaw |
Bigblock, Can you define for me the "difference" in going to N6 cams vs. stock, what it cost, and did you do the swap yourself? I have been thinking about it for my 99 M2 for the past year, and I am itching to do something. I have a Force, V&H and other stuff and am out of "things to do". I am very interested in hearing your thoughts as well as anyone else who has done this. | ||
| Bigblock |
Leeaw, The cams cost $275, I did the swap myself, get yourself a manual for your bike, and follow the Andrews specific instructions they pack with the cams. This includes placing the cams in your cover and checking that they spin freely, and checking installed cam thrust bearing clearance and checking for valvespring coil bind. I know it sounds intimidating, but if you have any wrenching experience, it's quite easy. As far as changes, after properly tuning your carb and checking your timing ( keep it stock unless you got a dyno)you notice only a small, almost negligeable loss of throttle response and low end power, and a noticeable midrange boost, and a huge gain in upper midrange and topend. I also suffered NO loss in fuel economy. Have fun! | ||

OK who wants to be the first on their block to try this with thier Buell? http://www.marineturbine.com/y2kinnov.htm | ||
| Chuck |
Sounds like a good way to win a Darwin Award! | ||
| Pangalactic |
Darwin award forthcoming or not, I WANT ONE !!!  ...hrmmmm, now how do I convince the wife how so very badly I need one..... | ||
| Pilk |
ohhhh YEAH BABY!!!!! maybe if I start saving pennies now???? or maybe I'll win the lottery. | ||

The company that makes these things in in Louisiana. The company owner has a Chevy S10 with a turbine engine. Jay Leno bought the first bike they made. There was a write up on it in Motorcyclist last year. Must be nice to be rich. Jeff | ||
| Rocketman |
Yeah, and the 2001 model has carbon Dymags too ! Must be nice to be rich I saw that Allison engined creation at the NEC last year. Interesting and definitely different and yes I'd like a ride if only for the sheer speed and acceleration, but for me, the Munch Mammot eclipsed it by a country mile. The Munch, despite its size and weight didn't look out of proportion. In fact, it looked like a conventional motorcycle, physically speaking, and I reckon it would smoke the helicopter bike no problem if they took away the 155mph restriction. Rocket in England | ||

 Well, it ain't a Buell, but I think the data still applies ... I did some work on my FXR on Sunday. Baseline is without the air cleaner in place. Magic valve is the same exact configuration, plus the Spyke Krank Vent device. That's a dead heat, folks, as close as any 2 dyno runs ever get. This is the 4th bike I've tested these devices on and the result has always been the same. I thought *maybe* it might do something on this bike since it's a '90 and it breathes off the crankcase, but I guess not. Magic valve & air cleaner is the same exact configuration, plus the air cleaner (a Zipper's big filter kit). Just some things to ponder, no big revelation here. Yeah, I know some of you guys don't like Harleys, but I love that FXR. Sometimes it's nice to just sit back on a big torquey rumbly bike and cruise. AW | ||
| Mikej |
Aaron, I thought you sold the FXR. Also, you said you got rid of the mid-range torque dip on the Buell with a stock exhaust muffler, how? | ||
| Aaron |
Mike: Sold the FXR? When hell freezes over! It's one of them long term relationship kinda deals. I really like that bike. I did 83 pulls on it the other day, tuning it. First really thorough tune-up I've ever done with it. Most of those pulls were dialing in the ignition. The more adjustments an ignition has, the more time it takes to get it right. Anyway, I rode it to work yesterday and today, and then today at lunch, the battery was dead! I just finished all the checks and all signs point to the regulator. Might've damaged it on the dyno, it was a hot day and I had no air pointed at it. No biggie, I'll try one of those series types. The bike I sold a year ago or so was my '97 Ultra Classic. I've had a couple Ultras. They're good traveling bikes, but man, they have a lot of doodads and gizmos and it seems like you're always chasing some little problem or some rattle or squeak. I've decided if I get another touring bike it'll be an R1100RT. Only other air cooled twin touring bike out there, far as I know. They seem better built than the Harley, to me. So how did I lose that mid-range hole on the M2? I'm not positive, I don't have the data to back it up and I don't have the time to go collect it right now. But, I suspect it's the intake side changes coupled with a lot of careful tuning (that bike has done a lot of dyno time, it's my best test mule). Think about how a flatslide works fundamentally differently from a CV. When you whack the throttle open, the intake length changes right away, it doesn't wait for the slide to be lifted by airflow. So your wave travel equation is totally different. Then hang a Force sidewinder on it, changing the whole intake length some more. See what I'm getting at? I suspect, though I haven't proven it, that the resultant effective intake length is a whole lot better tuned for that rpm (where the hole was) than the stock setup. But that's just a theory until I design and execute some experiments. When I get time. See ya, AW |
