A quick story on my Quicksilver carb. My California ST2 carb was giving me fits, high idle when hot, way too rich. A riding buddy told me he couldn't stand to ride behind me, I smelled like gas. That's embarrassing! I had already changed the intake seals so I called Edelbrock and got the tech line, Chris said I could get the carb rebuilt for $165. They rebuild the carb and upgrade it to the specs of the new model. It came back looking like a brand new unit, plus it has an accelerator pump. New slide, needle, seals etc. Put it in and the bike ran great except for leaking gas from the overflow pipe. Pulled the carb and used the float adjusting template from the manual and found the float about 1/2 inch too high. After an adjustment and some tweaking, the bike runs very well and has some snap from the pump when the throttle is cracked. Very nice, well worth the money and the tech support was excelent. Way cheaper than a Mikuni and I suspect easier to tune. I have read bad and good things on the carb. My opinion is that it is well designed for a simple carb. Better than the Amals on my old Triumph, but then almost anything would be. | ||

It's kinda cool that you still have the stock Quicksilver on your bike, it must be one of about one that still do. I'm glad to hear that it's done right by you. Maybe all the horror stories are just exaggerated. | ||

It's always refreshing that there's someone that has good luck with something EVERYONE else in the effing universe has shytcanned due to dismal return for their investment. Way to go Triman! My wife's caught on fire, twice. Converted it to a medium-range projectile. AL | ||

I did a lot of nosing around on the web and found that this carb has a long history. It has been used in dune buggies on VW's and is popular with folks that travel from low to high altitudes because it doesn't require jet changes. Like the Amals or Del Orto carbs, there are plenty of things about them to dislike. The early ones don't wear well. Once they start to go out of whack things get ugly. The current model has a lot of improvements, ball bearing throttle shaft, overflow pipe, redesigned slide, pump, etc. The Mikuni is a great carb, but I didn't want to have to tune it from scratch. We shall see, so far the bike runs better than ever, lots of power and easy to adjust. Will keep reporting. | ||

The HS/HRS Mikuni generally needs nothing more than 1-2 sizes on the main jet for any stock to mild motor. There are other circuits, but the HS/HSR (variants of the TM and RS) are already jetted for H-D applications. The Edelbrock is yet another in a long list of "perfect" carburetors by Mr. Edmonston. And each one is perfect and needs no other parts. As the designs progressed, each was advertised as "simple, fewer circuits and parts, easier to tune", and each successive one was more complex, with more circuits copied/adapted/borrowed/stolen from Mikuni, Kei'Hin, and very annoying to tune. Then he invented another carburetor with even more parts - first the Lake injector, then the Pos-A injector, then the Lectron, then the EI, then the Edelbrock QwikSilver, QwikSilver II, and Performer. Previously: "doesn't need an accelerator pump, only needs 1 circuit". Now: "a true 3 circuit carburetor, includes an accelerator pump and easily changed air bleeds and jets". Yes, it now needs 1 main and 2 air jets, along with needle height and rotation. The needle is rotated to make adjustments. What to do if this is not successful? You need another needle - exactly like the Mikuni. Except that the Mikuni needles (there are only about 4 that will work) are available inexpensively all over the planet, and the Edelbrock needle is ??? There are 33 different QwikSilver II needles listed- but none are available, and no one knows if they fit the later Performer carburetors. No one seems to know where to get one - the Edelbrock home site does not list any carburetors, let alone parts. PS: I paid $75. for a Mikuni with 100 miles on it.} | ||

Triman - your profile says you are in Pasadena. I'm in La Canada. That wasn't YOU that yelled "HEY!" "That HURT!" when I hucked that less than functional, ramdomly activated motorcycle auto-detonation/destruction device (AKA: Quicksilver II) over the fence, was it? AL (sorry - just kiddin'!) | ||

Al - You'r killin' me, man! I haven't made up my mind about the CA S2 original QS yet. Haven't spent the time trying to get it to work any better. Mine doesn't quite return to idle and on inclines, declines, or hard braking with driveline disengaged it drops idle and wants to die. I do have another QS (WAY long story) that was upgraded by the factory and has the accel pump. I toyed with the idea of mounting that thing up - but the thought of waiting around for parts from what looks like a marginally supported carb doesn't enthuse me. I really wanna open the thing up, clean it up, adjust the float, and see what gives.... -Saro | ||

Al - I thought I saw a shooting star the other night, guess it was a QS carb flung over Pasadena! Edelbrock's tech line is 800-416-8628 I talked to Chris, they also do email. The Edelbrock site has a listing of parts under carb accessories. Parts listed may or may not fit the Quicksilver II. Ask. It's probably not perfect but the bike is running quite well ,so for today, I am fine with it. | ||

When that carb on my wife's bike finally put me over the edge of my usual infinite patience (It would soak the air cleaner element with gas while idling - you could see the mist of fuel eminating from the carb throat when the a/c cover was off and bike was idling - a little puff out of the carb with every stroke!) I took it off and replaced it with a slightly re-worked CV from a friend's S1. I also had to replace the air cleaner cover as that piece of sh...oops - "difficult for me to adjust" - carb incinerated the nice (though oddly greenish-tinged) carbon fiber unit that came on the bike. It ran great with the CV and narry an untoward moment resultied from that exchange. Well, except for when she almost went over the side on Little Tujunga Canyon - but that was rider, not carb, error. This has been a few years since all this ruckus so that may have actually been a shooting star you saw, or maybe it was an errant tracer round from Huntington Park . The carb resided on the wife's S2T, which was sold a few years ago - she was always more comfortable riding my RoadKing! AL |
