hiya peoples...
my b4 is a little poorly :( and i have been told by my garage that it prob needs new needles and jets in the carbs... ok fair enough so the all important questions is.....
1 where in the uk can i get those parts?
2 are there any parts im gonna need to get for when i change them?
thanks

You might be on a scavenger hunt, my friend. Word is Suz/Mikuni stopped making the jets. That was reported on one of these threads, anyway.
-
IIRC, the Factory-Pro jet kits are still available for the B4, so your solution just might be to rejet it for more power to cure it.
That is if the Factory-Pro kit is compatible with your bike.
Which market model is your B4?
-
What are the symptoms? Depending on what's wrong a jet kit might help.
Dynojet and Factorypro both still sell bandit 400 kits. However, the kits only come with main jets, jet needles, and springs. If you need a replacement needle jet you're on your own. Suzuki has them listed as discontinued.
Here's the factory pro website

While you're at it -- no carb rebuild is complete without changing all of the o-rings. Depending on what's wrong with your bike this might be the only thing required... last I checked you can order all the o-rings from Suzuki (although you'll pay an arm and a leg, you are guarenteed that the o-rings will fit and hold up to petrol).

I used the Factorypro kit with a Canadian model bike (33mm carbs). It took some tuning, but the Factorypro settings for the US model bike were pretty close. I found it a bit too rich in the bottom end, which I corrected by modding my airbox and then increasing the MJ size...
Last weekend I pulled my plugs, compaired them to the plug chart and to my amazement I had the perfect plug. I wish my camera had batteries!

What?! :shock:
I don't believe it! The Perfect Plug is just a myth, a legend told by old mechanics to keep the younger ones in line! It's like Santa Claus or the Easter Bunny, it doesn't actually exist!
-
It's no myth, I've got one in my toolbox that came out of a Pratt & Whitney R-2800 18 cylinder radial - too bad the plug's life had been cut short by a sucked valve.
:btw: lots of FI engines have 'em.

:banana: I hve them to 4 of them I just change mine for shits and giggles but i have race carbs :stickpoke:

Yup! Then someone posted that they were all gone. I figgered I got the last ones! Someone has to get the last ones, right??? :wink:
-
well lucky you , but i can check my sorce! :beers:
-
Have you checked that it is running on all 4 cylinders?
-
Jay,
I'm interested in new jets too. Please check your source for me too. Thanks.
-
yup its running on all 4.

First thing I'd check is that the bike running on all 4. Start the bike up and let it idle for a few minutes. Then carefully/quickly touch each of the header pipes and make sure they're all getting hot.
If all the pipes are getting hot. I'd try doing a carb sync. If your tach needle bounces around at idle chances are your bike will run a lot smoother after a carb sync.
If the above suguestions don't solve your woes, then you are looking at opening up the carb and seeing what's worn... if you don't feel comfortable doing that, I'd recommend taking it to a shop who knows what they're doing.
-
Hey Jay, definately if your source is able to come up with the needle jets I would be interested.

Okay Fooker 76.00 shipped in the US :stickpoke:
-
Hey Jay,
I'm not trying to step on your sales as that's a very good shipped price. It just seems that people (I know that I did) think that these parts are no longer obtanium from the regular dealer/online (the whole needle jet, jet needle, needle, jet, jet, needle thing). They are. The part that is no longer obtainium from Suzuki is obtainium from Factory Pro - and adjustable at that :).
I'm trying to make up my mind what parts I want to lay in for the future and these are being considered.

Just :stickpoke: fun with ya man! :beers:

:lol:
Hey jcmjrt, which part are you referring to as unobtanium from Suzuki?
Since you mentioned adjustable, I am guessing that it is the needles that are no longer available from Suzuki?Or am I confused?
Anyways, $76.00 shipped is definately a good price. :)
-
It's least likely to cause confusion if you refer to the parts fiche (which is available as a sticky up top here) in the 3 page carb section. The unobtainium from Suzuki parts that I know about are #12 and #28 California Only. The other two types of #28 for Model M/N and Model P are available. A substitute for #12 is available from Factory Pro - the adjustable needle in their rejet kit.

Needle jets (emulsion tubes) the jet needle runs thru this.
jet needle (needle) this is usually adjustable and what comes in a jet kit
slow jet (pilot jet) this is the jet that controls from 1/8 throttle to @ 1/2 and is the smallest jet in the float bowl
main jet -connected to the emulsion tube and what feeds the needle and also the biggest jet in the float bowl
fuel / air screws these can be on the top ,bottum,side of any carb and vary in turns from 1/8th to 3 1/2 and control idle to just off idle
**** What i wanna know is how many of you have the rubber plugs in the slow jet hole?************ :stickpoke: :duh:
