Are the factory QuickSilver carbs that came on the california bikes better than the CV carbs that came on all the others?? I can buy a used one for pretty cheap but I don't know if it will be an improvement over my stock carb. My bike is 96 S2 with stock heads and cams. | ||

Not Purple,I have had all 3 carbs on my S-2's.The QS was ok,the CV on my non CA S-2 works just fine--mileage about the same with both-.Now I have a Mikuni 42 and it really woke things up.Advantage to the QS is the ease of adjusting jetting.Access hole in top allows quick adjustment if you get the Edelbrock piece for that.Make sure the carb is a later model one.Somewhere in there they had a recall on the QS on S-2's.I only found out by accident when the slide cracked on me.The newest QS has a accellerator pump also.BTW,on the QS you will need throttle cables from a CA S-2,for the later Mikuni stock S-2/Sportster cables work. | ||

thanks I don't think I'll bother with this one then It's from a 95 S2 I think I'll just save back till I can get a Mikuni, they seem to be the most highly praised choice | ||

Does anyone know where I could find a external fuel pump equal to the one in the tank on the X1. Or at least head me in the right direction. specs: 49 psi 14 volts 70 LPH @ 49psi 3 amp draw Thanks | ||

My Idle mixture screw backed out of the Dyna's carb. It be long gone. I looked at Creative Cycle Product's page - and they sell a replacement spring / washer / o-ring deal for like $16 or $17. Seems kinda steep. Any input? Most of the HD shops are closed on Mondays around here so... -Saro | ||

they are not available for my M2, nor for a sporty, from the dealer . . . . . I had the same problem a month ago, and wound up going the Creative Cycle route | ||

Hey, I'm looking for some feedback on how far people have pushed the tuber race ecm in terms of power delivery. I'm contemplating sending my S3's heads to Nallin's for some work with a possible 1250 kit thrown in for good measure (already has the full race kit). Anyone done this without using the powercommander? Kurt | ||
| Jdbuellx1 |
Right now I'm running Nallin stage II heads, 1250 kit, forcewinder aircleaner, S.E. 536 cams, and Nallin/Force streetfighter pipe. No power commander, had it on the dyno and only shows a lean spot under 2500 or 3000 RPM, almost perfect after that. Aaron Wilson has a dyno chart of a X1 with almost the same set up as mine on here somewhere, race ECM seems to hold up rather well, I'm going to push mine a little further in the spring and see what happens with it. | ||
| Knickers |
Thanks for the feedback JD. I think I found the chart you refered to. Apr 27, 2002 in the dyno chart KV. | ||

Jd Weber makes a 50psi inline pump that flows 84gpm...no doubt overkill and any other specs are beyond me. They make another that's a little more reasonable at 45psi/34gpm. I think any external pump flowing over around 15psi is an automotive race application sorta deal. | ||

Rick- High pressure pumps aren't necessarily for race use - they're for FI. -Saro | ||

Anyone know what would be involved in converting an M2 engine for use in a x1? Found an Nallinized 88" M2 motor for sale, an I figure converting it can't be that hard to do. Only prob is the Motor is set up to run 2 plugs per jug. Will this conversion be a piece of cake or would it be better to run the carb and convert the X1 electronics? thanks | ||
| Aesquire |
I suspect that with a 88" motor & good headwork (Nallin does GOOD headwork) you would need a powercomander & some solid dyno time to get it all sorted out. I'd go with the carb. FWIW | ||
| Rick_a |
Saro, I'm not talking about pressure...look at the specs and they have tremendous flow numbers compared to what's neccesary for a motorcycle application. I haven't seen a suitable externally mounted high pressure pump for a bike anywhere. The stock Buell pump flows 70LPH, most of the external auto pumps flow that in GPM. Big difference and way overkill. | ||
| Sarodude |
Rick- I was referring to:
I didn't look at the Weber site or anything, but yeah, 70 LPH vs 84 GPM does seem like a rather massive difference. I'd love to see a bike that needed 84 GPM! Maybe that Dodge RoboBike thing with the V10... -Saro | ||

Help! Check engine light started coming on and off. The diagnostic says it is not reading the O2 sensor. I have a Standard Motor Product SG27 heated O2 sensor and a race only ECM. Both were installed 2000 miles ago. Any ideals on who the culprit is before I buy another O2 sensor? Thanks. | ||

Help! Ran my 99 x1 out of gas on a German autbahn. Fueled er back up and she is running real rich....? Ran the bike to reset the ECM, no help. | ||

'99 & '00 FI Buell owners. Remove your air cleaner assembly and inspect your throttle body shaft for cracks. (Especially after 20k miles)This may not be an uncommon problem. I was told that Buell updated the throttle body mid-year 2000 to correct it. DAve | ||

ANyone else have problems with new throttle cables not fitting correctly? The housing on the cables are about 1/8" longer than on my originals. Not much but with the throttle and idle cable combined, it equates to 1/4" difference which is substantial.    Even with max free play adjusted, I cannot get the both cables on and in place without bending the bracket on the throttle body holding the cables. After slight "tweaking", it was enough to get the cables on but its too tight and the throttle won't return. So I untweaked the bracket. Yes...cables are routed correctly. This is a new Throttle Body as well. Ideas on how to address? Brian, Dave S or any other dealer guys? Have a cable on the shelf to see if what's up with this? p/n N0307.KA Throttle Control Cable p/n N0308.KA Idle Control Cable (6/18/01) DAve | ||
| Dave |
Problem...differnces in throttle bodies cause the cable draw to be longer...fock.  DAve | ||

HD-Buell Customer Service...they checked with their technical people and they were aware with a problem with these being manufactured with the wrong cam. Son of a bitch.... here's to another week. DAve | ||
| Josh_ |
Can't you swap cams? | ||
| Dave |
I looked at doing that JOsh but was put off with the thought of tweaking that butterfly shaft or butterfly on a $100 part. Plus having to fock with the spring. They did ask me to send it back with some reference number so they can look into how many more are out there. DAve | ||
| Dave |
Tech Services Dept called me back and let me know they've gone through a very detailed and exhausting process of running down all of these renegade throttle bodies with incorrect cams. Supplier probs.... Anyhow...a correct one is on the way to the dealership. That personal phone call to let me know what was going on speaks volumes of the customer support I've received from Buell time and time again. DAve ...hell no! My Thunderbolt is 100% stock I tell ya..... | ||

So.. I go on a nice 2 hr ride in the beautiful Ozarks (on my '98 S3) and at the half way point it starts running like crap at low RPMs, I figger just the altitude difference between there and home. but, it does it for the remainder of the ride Coffing and spitting at anything below 3000. Upon getting it back into my garage, it proceded to deposit a nice puddle of fuel on the floor. Taking off the cover for the race air cleaner, I see fuel and bubbles coming from the two small holes at the bottom of the venturi. So when I dive into it tomorrow, or so, do I look for a plugged bowl vent, or a stuck float? It has ran nasty from time to time, but only when I ride it enough to get it real hot for a long period, but this is the first time I have witnessed it bubbling out fuel. I run the race A/C with just a venturi ring, and nothing is obstructing the bowl vent hole, at least in that area. I am gonna tear it down for a thorough cleaning regardless, but would like an idea as to where to look to find a cause. I would hate to not find anything out of order. I have been in the carb numerous times getting it tuned for this altitude, and am usually very good about cleaning it each time and checking all circuits, so, in the back of my mind I'm thinking it's clean. will see. Any thots appreciated. jim | ||

Passion started running bad (wouldn't take more than 1/8 throttle) about 2 weeks ago just out of the blue. First thought was clogged jet. I tried to run it out by pumping gas through. No luck. Today I tore off the tank cover and tank and started to remove the carb. First thing I noticed was one of the wires from the VOES was flopping around. I dug out the potting and reattached the wire to it's terminal and used some candle wax as potting. First test drive proved it was fixed and running strong. I guess I'll get a new VOES just in case.

If your fuel pump has become rather noisy, an ounce or two of Marvel Mystery Oil dumped into a full tank/frame full of gas will get it running quietly again. At least it did on my Firebolt and it's also supposed to help blast out carbon build up, lubricate the top end, cure impotence, etc. It's also been recommended by several people as a means of cleaning sludge and crud out of noisy hydraulic lifters: dump some in the oil 100 miles before a fluid change. I haven't tried this so can't say if this works or not but it's worth a shot if your bike's clattery. | ||

Hmmmm, No hints, ideas or speculations?  | ||

caveman, sounds like a float level thing. also check the float needle for wear or junk on it. seems like it should be passing fuel from the overflow hose if it is a float problem. your motor is'nt running so hot that it is percolating fuel in the carb is it? just a thought. | ||

OK, here we go... Does anyone know if the US Race ECM for the XB12 will operate on European models? Can it be run with the stock pipe (eg - is there the valve control mechanism in the race ECM or was this entirely discarded?) Does the PCIII work with either the stock ECM or the race ECM for the 12 and if so any experiences out there to mention? I have plenty more questions but don't want to get too far off topic. BTW - Blake, with all the questions around the ECM - would it make sense to have an ECM dedicated section in the knowledge vault? I've been looking all over and find there are hundreds of threads relating to ECM questions but are all over the place (not a shot, just a thought) - ..hmmm..., I'll have to use that line again! |
