MZ/MuZ Riders

I have been searching the posts for a US source for a carb kit for my Baggie...Bike Werks no longer appears to have them? Does anyone have a source that they could share with me? I have a lean condition at partial throttle (sort of farts and pops, and sometimes stalls) when blipping the throttle at slower speeds, or when just cruising along at 1/8th throttle or so. Started doing this when pipe was installed. Have tried adjusting it out with the mixture screw, with limited success. Please help...I would like to fix this over the winter months. Thanx!!!

For special problems please send questions to:

here is the ultimate carb tuning reference on this site:

carb modifications. The mixture screw gets backed out(holeshot performance recommends 7 1/2 turns out from lightly seated),the main jet isn't adjustable, you replace the 130 main jet from the left side (as you're sitting on the bike)carb with a Kehin 135 and screw it in all the way tight. The midrange jet needles (both sides) get raised 1 notch, (this means the cirlip goes in the second groove from the pointy end) cut 2 coils from the constant velocity slide spring (right side)and re-install cut side down. Be sure to line up the diapraghm correctly, there is a little tab on the edge of it that fits into a recess cast into the top of the carb. At low altitude (below 5000 feet), you can drill the right carb's main jet with a #51 drill bit, just twist it between your fingers, no need for the drill press and re-install with a new P/N 90-20.142 crush washer. For around town riding this last step isn't really nessesary, you'll foul plugs more often and you should definatly keep a stock main jet (P/N 90-20.146) handy if you plan on doing any riding up in the mountains. The sync screw on top of the carb bank controlls the point after the low speed carb carb starts opening that the high speed carb begins to open, crank it in a turn or two so that as you twist the grip, you'll feel the freeplay take up, then the low speed carb start to open, then the added resistance of the high speed carb opening. You want the high speed carb to open just after the low speed opens, without as much of a delay as with the stock setting. This obviously needs to be set with the carbs reinstalled on the bike before the gas tank is replaced. Lastly, if yor bike is a Skorpion (Sport, Traveller, Replica Etc., not a Mastiff, Black Panther Etc.) Remove the black rubber snorkel from the top of the airbox. Of course, all these modifications are recommended for closed course, racetrack use only. Wink.

go to your local Yamaha dealer, and ask for the Diaphram from an XT600, or Raptor. I think they are the same as our carbs

there's them and SUDCO, but that's why i was asking for carb specs, starting with the size / model of carb.

i know the ..right side carb is a Teikei [spelling?] but what is the CV carb? is it also Teikei? and what size / model are they?

in europe (and wherever else they had them), XTZ660.

it would be better if we knew exactly what carb it is.

Hey Kerry, if you go up Higby Rd and then over Roberts Rd, heck you'll be in my neighborhood!

Hey thanks guys! This site is the best...now out to the garage to begin the "tear-down" and ultimately (hopefully) a better running bike will result!!

they are both CV carbs..

i was under the impression that only the 'secondary' carb was a CV .

no-one seems to have ever said what carbs they are, only that they are Teikei.

as for carbparts.com, their website still doesn't work - like it didn't work when i went there months ago, and the other major carb parts people on the web seem to do only Keihin and Mikuni.

ok, it looks like you're right -- but they look different in the diagram here:

although - as per my post
http://www.mzriders.com/viewtopic.php?p=6337

MZ 660 Teikei Y26PV Primary 130 Secondary 165 (50PS)
XTZ 660 (3YF) Teikei Y26PV Primary 130 Secondary 165 (48PS)
XTZ 660 (4MD) Teikei Y26PV Primary 122 Secondary 165 (46PS)
XT 600 Z (3AJ) Teikei Y27PV Primary 165 Secondary 125 (46PS)

The left carb (primary) is a slide carb, the right carb (secondary) is a cv type.

maybe that list i posted was just for the one carb. i'd better look at it again. YPV -- i don't know if that's the cv one or the other. then what's the "Primary 130 Secondary 165" ? main jet sizes? must be. but that implies that the carbs are the same, just different jetting, and they're not. arrrrgghhh!

one has a low speed circiut, one does not.
