I'm in need of conversion factors between international standard units and american stuff... How much cubic centimeters in one oz please ??? | ||
| Idzerda (Hans) |
Jerome: 12 ounces is 355 cc (354,8823548 to be precise) Rocket: 12 UK ounces is 341 cc (340,9569 to be precise) Hans | ||
| Idzerda (Hans) |
Found somewhere that you need 220 cc for each HP/hour. 355 cc/minute is 21300 cc/hour That makes 21300/220 HP max. That is not more than 96.8 HP. Uhh, What is wrong here? Hans. | ||

Hi Guys, Pingel valve# 1211-AH, and adaptor # A1602C-B are required. Phone 'em at 608-339-7999, fax 9164, they will C.O.D., and they're real nice, too. Cost me 80$ delivered after COD, nice price, looks good, too. Tim- although I lost a little throttle response and low end, really only noticable in 5th gear, the N6's way more than make up for it in midrange and topend power. She still does off-idle 1st gear roll-on wheelies, and will keep yanking the front end all the way to the 6800 rev limit if you set er back down. It'll bang the limiter with authority in 2nd, and pretty easy in 3rd, too, and if you abuse 4th a little, the front tire might get a little air. Sorry, no dyno figures yet, but I'll post em if I get em. Jerome- My bike averages about 40-42 mpg, a best of 50, worst about 37. I check every tankful with my tripometer. I live on the North of San Fran on the coast, Pt. Reyes, so most of my riding is curves. I only had er up to 130 (indicated) once, and I probably average about 65 mph. Hans- I'm suspect of your hp/hr info, perhaps they mean 100% efficiency? Then again, just because I got 12oz/min in my flow test while the bike was off and parked, doesn't mean that's what it actually flows riding her. Anyway, Pingel claims you need atleast 24oz/min to feed a stock bike properly. Anyways, all I really know is that my bike runs a lot better with the new petcock in it, especially at the upper rpm ranges. Believe me, it made a very noticeable difference, and my plugs dont read super lean at hi rpm wot shutoff like they used too. Ray | ||

Anybody have an X1 with a Dynojet Power Commander and a V & H slip on? Just wondering if the power increase is worth the cost. Please send emails to mjsinka@otenet.gr if you have any info on this. Thanks. | ||

Pammy from Cycle-rama claims to have 97 RWHP from this set up, on an X1. SOME OF US DON'T BELIVE IT THOUGH Rocket in England | ||

Ray, I'm a little confused about the difference in the petcock flow number you measured and what I measured on mine a while back. If I'm reading it right, your petcock flowed 12oz/Min. My notes say mine flowed 39oz/Min on the main and 51oz/min after a fifteen minute mod. Anyone else done this test and have numbers to compare? I'm just trying to figure out if my petcock is doing the job. I've been wondering about it. Thanks PB | ||

Interesting discussion about petcock flow. I've felt that the high carb position on H-Ds contributes to flow problems(low fuel pressure.) I haven't done any tests, but with the wide (reported) variation in flow it implies fuel tank breather problems. In the case where the bike is going lean near 'Reserve' that's dangerous! A low pressure fuel pump should go along way towards jetting consistancy. | ||
| Bigblock |
I had a problem with my tank venting system, but I cured it by tossing the charcoal cannister and making sure the breather hose was routed w/o any kinks, and not ziptieing it too tight to the frame. Since then, the tank venting seems good. This was several thousand mi. before I discoverd how poor the stock petcock flowed. Plus, I did my flow test on it with the gas cap OFF to make sure that was not an issue. My flow test was done with close to a full tank, and running the fuel line into a 2 1/2 gal can. It took 26 min to fill the can to the full line, an average flow rate of 12.3 oz/min. There was still well over a gallon left in the tank, and I even switched to reserve about 15 min in, with no visually detectable change in flow. I then proceeded to dissassemble the valve to check for debris internally, or in the screen, but found none. There was also no apparent deterioration in the appearance of the valve internals. And, with the Pingel in, the bike just runs WAY better. I have not done a flow test on the Pingel, but I did a visual check, and when you turn it on, it just GUSHES out, in a stream that almost looks as if it were under pressure, whereas the stock valve just trickled. P.B., if you are really getting 51 oz/min, and your motor is stock, I would say you might be alright if your motor's not leaning out on top(the reason I finally checked mine, my plugs always read real lean at hi rpm) but after what I've seen w/ my M2, and every Sportster valve I've ever checked ( I realize they're not the same valve, but they are scarily similar in their lame design) I am recomending valve replacement to everyone I know, as it is cheap insurance. By the way, I really like the idea of low pressure pump, a friend and I have benn talking about that for a long time. Probably a good idea if you were running 2 carbs. speaking of which, if anyone has, or could point me to someone one or place that has, it is something I am real interested in, something I would love to run if it would work on the street. Thanks for listening, guys...Ray | ||

Bigblock : could it be that there is significant variability from one Buell petcock to another in terms of flow rate ? On my Cyclone, I had to decrease the main jet by 20 points (from 195 to 175) in order to get slightly rich mixture at wide open throttle. With the OEM 195 it was way too rich. This means that the petcock on my bike is not a limiting factor. I've never opened it. Is the valve only a piece of plastic with a hole inside ? If this is so, it's possible that the hole diameter does not remain constant on the production line. Food for thoughts... Thanks for this new headache anyway ! | ||

Ok, you guys got me wondering, so I went back and retested. I did it a little different this time, though. The first time I tested, I measured how much fuel would flow into a calibrated container in 10 sec. In this test I measured the length of time it took to fill a 1 gallon (128oz.)container. This was done with 2 gallons of fuel in a S1 tank (on the bike) draining through a 5/16" fuel line to a 1 gal. container on the floor. The results were slightly different. 34 - 35 oz/min with the valve in the "Main" position (the tube has been removed from inside the tank). 42 - 43 oz/min with the valve in the "Modified" position (the valve has been modified to flow both main and reserve at the same time). Mr. Dickey, According to Mr. Denish, gasoline weighs 6.2 pounds per gallon. In which case Ray's motor would only be capable of producing 69.75 gross hp or 57.89 net hp (using your numbers) with that kind of fuel flow. Somebody, please, check me on this. Sure would like to see some flow numbers on one of those Pingel valves. This is all very interesting. I think I need medical attention. PB | ||

BigBlock, very thorough testing. Are you aware of the reports about dual carbs on my homepage? http://www.visi.com/~moperfserv | ||
| Axtell |
Yes ,you are right about the fuel weight---Ron | ||
| Eeeeek |
Ron, Could you tell me if this sounds right and what could cause it? I went to Auburn where I got to hold the damaged pieces of my engine. Here's what I know for sure and bear with me if I don't know all the right terms. The connecting pin, the main one that connects the crank to the connecting rod, had a nice big groove in the top of it. The groove matches up to the bearings perfectly, so the bearings must have been wearing the pin away sending little shards of metal through the engine. I've heard that there was a while when H-D was getting soft connecting pins, but I can't confirm that. Evidence of the shards were everywhere: the sides of the pistons, the lifters and etc. It looks like the filter got most of the shards, but not until after they had made a trip through the engine. The pistons were deep in carbon, too. From this information, what can you tell me? Vik | ||

AIGH! I what happened to the double-post killer? | ||

Hey everyone, I recently did away with my stock air box . . . and since I don't have a dyno in my garage, I concluded that after achieving satisfactory driveability, the next logical step in evaluating this mod was to conduct a "high speed" test. To make a long story longer . . . My M2 topped out at an indicated 130 mph, part of which was done while traveling up hill. I also concluded that the opening in my stock petcock must be reasonably adequate as it took a short while to reach this velocity . . . I know that you are all relieved to have this news. | ||
| Bigblock |
Jerome, I don't doubt considerable variability in flow from one stock valve to another, but it is n't just a hole in plastic. it is a rubber maze for fuel to flow through, basically the same thing as a sportster valve, if I would have known that at the start, I would have probably replaced it right away. However, if your motor is stock, and you are SURE that you are consistently getting adequate fuel flow, then I guess you're O.K. P.B., If I remember right, I believe Pingel claims 85oz/min, but I can't confirm this at this time. Moperf, (sorry, I don't know your name) thanks for the website address, I'll check it out. Clear roads, all... Ray | ||

http://www.pingelonline.com/ Quote from Pingels Website... ...The Power-Flo single outlet model has a flow rate of 85 ounces per minute, the Guzzler an impressive 211 ounces, and the baddest boy of all, Pingel's NV Nitro Valve delivering an incredible 9 gallons per minute!... After following this discussion, it seems that they may be a worthwhile update to a bike that is already tore apart for winter cleaning. I have a question though, actually three. 6311-CRF H-D Metric & Nut is the one i would order to suit my bike. This would fit the buell tank right? They have no prices on their site, how much are they? And, are these the same people that make some sort of catch can for the crankcase breathers? Or was that someone else? I thought I read that it was Pingel, but i didi not see anything about it on their site, so i am doubting my memory (wouldn't be the first time). Travo | ||
| Loki |
Travo, It be PINGEL. You need to get thier catalog. Or if you call them just say you are looking for thier catch(puke) can. loki | ||
| Xlwp |
Ray, Travis, Thanks for the flow number on the Pingel valve. PB Ride it like ya stole it | ||
| Travis |
I think i will get their catalog. Thanks Trav-a-roni - The Indiana Treat  | ||
| Bigblock |
Doug, I really liked your page on the dual carb testing, thanks. Too bad the bike pic wouldn't download. Do you know if anyone is making dual intakes that might be in the ballpark for cv's, or am I gonna haveta to do what you guys did, and start from scratch? Thanks, Ray | ||
| Chuck |
I'm not a physics major, so I'll ask a stupid question. Will a high flow Pingel fuel valve cause a greater head pressure to be "applied" to the carbureator? -- and if so could this higher pressure overwhelm the float and needle valve? Wishing I'd had more college. Chuck. | ||
| Peter |
Chuck, No. To get higher head pressure, you would have to lift your tank higher. It's been a long time since I learnt it, but I think for every 27" increase in height (with water, at sea level etc), you get an increase of 1 psi. (My memory could be bad. It was 20 years ago). The Pingel just allows a greater volume of fuel through in the same amount of time. PPiA | ||
| Xlwp |
Peter, All things being equal, wouldn't a larger column of liquid yield a higher pressure for a given height? PB Ain't no engineer either | ||
| Xlwp |
Ahhh........but nobody said ANYTHING about a larger fuel line, did they? Sorry. I was thinking about my standard CV40 mod, 5/16" fuel inlet fitting and line. | ||
| Peter |
PB, Even with the larger line, you are still restricted by the the seat diameter in the carb. PPiA | ||

I have a '99 X-1 and i have not changed any of the fuel injection or ignition components. I did add a K&N filtercharger, and a Vance&Hines SS2R slip on. I got better power by doing this but sometimes when I go to crack the throttle open I get a sputter or a miss. Seems to only happen at lower RPM. Would getting a different ECU or any aftermarket injection components help this. I really dont have any idea what could help. And should I have to pay for this or do you think I can talk my dealer into warranty parts? Just hoping. Thanks for any info. Red | ||
| Rdrage |
Red, I have the same problem! I had the the Kooks exhaust system, Race ecm and a K&N. The dealer told me there was nothing he could do. I installed The Power Commander but I haven't dialed it in. There's no maps for my exact combo. I'm gonna take it to a dynojet tuning center as soon as I can afford to, After X-mas. I hope THAT works. I couldn't get my dealer to help, hope you have better luck. Let me know. | ||
| Chuck |
I sure am glad my M2 has a carburetor! | ||
| Moperfserv |
Gotta comment on 99Buellx1's question 'should I have to pay for this or do you think I can talk my dealer into warranty parts?' Your warranty applies when you don't change anything. If you have a helpful dealer they won't void your warranty when you do change something, anything. As far as your FI system goes, I don't think there is anything that your dealer can do with available stock parts. You willingly spent the money for the parts, now you have to willingly spend the money to make them work. Or you don't get your moneys worth. | ||
| Boomer |
I couldn't get a response on the general discussion area so I'll try here. Trying to get some feedback on the benefits/detriments of the HSR42 carb and Nallin stage 1 head work. I already have the factory race kit with a Yost kit in the carb. This is for a '98 S3T. | ||
| Aaron |
Boomer: I've had Brian port several sets of heads for me. I'm assembling a motor with his heads this weekend in fact. He has always done outstanding work for me. The end result always seems to exceed my expectations. Really, I think your best bet is to call him and discuss your project. He's the real deal, he won't BS you. And he's good people. Good luck, AW | ||
| Boomer |
Thanks for the response Aaron. I'll give him a call. The head work prices seemed very reasonable that's why I was curious about the work. |
