Its been a long time but after almost 1 1/2 years i finally got the Bandit to the workshop.
Got it started after all this time with only a new battery but would only run on 1 cyclinder.
After freeing the frozen master cylinder & loading it onto the truck,we found 1 of the pilot screws are missing!! :annoy:
Makes sense to buy a new set but after looking at bike bandit & alpha spares,the part is not listed as a pilot screw ? ( 4 of them including seal & spring )
Most likely i got the name wrong.
Cheers.

Try www.bikebandit.com I've bought things as small as one washer from them.

If you can't find a new set I have a used one you can have.

Whats your bike a 400 or a 250 and what year?
I found this microfiche on www.bikebandit.com for the 400 but the pictures kind of lousy and I couldn't see any obvious pilot screw.

I looked for the Bandit 1200 carbs and it was only $8 so don't sweat it you're not going to break the bank getting a mixture screw. I've given away parts that cost more so maybe even a wrecker may have one. You'll need the spring and seal but those can probably be at like home depot or something that will be the equivilent. Don't pop in the mixture screw without some sort of a spring and a seal. Even a ballpoint pen spring(probably similar) would be better than nothing, otherwise it will just fall out again. I've gone to Rona before in their rubber washer bins and have replaced some small o-rings I've lost and they work perfectly so it shouldn't be hard to figure out one that will work. Do you know how many turns your out on the screws with the other carbs?
-
Thanks very much for the offers,unfortunately i live in Bali & postage would probably cost more than the parts.
I know the item as an air screw or pilot jet but we cant find it on the Bikebandit m/fiche or the dealer in Singapore ?

Are those mixture screw plugs lead sauder???? Weird. Do you have any motorcycle wreckers on Bali? or do you find the screw and just need the spring? I just sent a bunch of mainjets to Australia for $1.50 through the mail it might not be that much it's just a screw and a spring. I don't know if you can even buy just a mixture screw for that small a bike. Maybe a carb parts warehouse would have one.
What year and CC of the bike is it? I could figure out what carbs you have and maybe go to carb parts warehouse or something.

Thanks for the replies,nice to still find so many helpful folk on this forum.
The bike is a 93 GSF 400 & there are no carb shops or bike wreckers here in Bali / Indonesia.
10 years ago there were many big bikes brought in without paying any tax but in the last few years that has changed so my bike has become pretty rare,spent over 2 years doing a full rebuild with the help of some forum members in shipping parts.
Messages to Mikuni themselves to find an agent in this area have so far got no answer & its confusing to not be able to find the parts on the microfiche?
I have sent pictures to the dealer in Singapore & hopefully he can identify the part numbers hopefully order a complete set of 4.
The screw has fallen out,including spring & washer,possibly the mech forgot to install the screw??
-
Well I downloaded the gsf400 microfiche from this site and there is a pilot screw there number 47 in the parts diagram but its ironically missing from the parts listing it goes 45, 46, ..., 48, 49
Bizarre....
Do you know what make and model of the carb?
Ie BSR36SS <----Bandit 1200 carb
Then you could actually order the parts from Mikuni directly. I'll try and find out what it uses for you.
EDIT: K found the carb model-->>BST32SS
States use BST33SS 1mm larger
This helps alot now we can try and find a parts replacement from Mikuni. I wonder if a pilot screw from another Mikuni carb that is similar would work. As long as the threads and the taper are correct, all it is is basically a tap for a metered hole. Even if the taper was off you could tune it to the other cylinders. Although I'd wager a $1 the 33 mikuni pilot screw would work.
Some other bikes that use the BST33SS carbs:
Katana 600 1988-97 %99 uses the same pilot screw
After 97 they use the BSR32SS possible fit.
Carb: BST33SS
96 Katana 600 Microfiche. Pilot screw + springs and washers #40 - 43. DONT GET THE PLUG #44. Total cost about $20 From the shitty diagram this looks the closest to the pic. I would get this one.
http://www.bikebandit.com/1996-suzuki-gsx600ft-katana/o/m6175#sch278775
Carb: BSR33SS
2000 Katana 600 Microfiche Pilot screw + crap 25-28 DONT GET THE PLUG #28A Total cost $16.
http://www.bikebandit.com/2000-suzuki-gsx600fy-katana/o/m6179#sch243509
Do you know if you have the 33mm or the 32mm? Measure on the engine side if they are the 33s just order a pilot screw from a 88-97 Katana as they are the same carbs. I would wager they use the pilot screw even if you have the 32mm if you want to take a chance for $20. If it was me I would take a chance on the first option the 1988-1997 Katana 600 Carb which is the same model just 1mm larger. Thats the first link I gave you the '96 Katana 600.

Wow,
thanks so much for the help.
I was thinking the same that it should be a standard thread across different models of Mikuni & still trying to get an answer from them.
Which ever part i get will have to be ordered,scooters are the main selling items here & the newer ones are coming with F1.
From memory its the 32 mm version but will have to check the nike at the shop sometime.
This is the site in Singapore that i mentioned..

If it's outside the States I would wager it's a 32mm however the Katana 600 uses the exact same model of carb but it's a 33mm not a 32mm. Try getting a pilot screw, spring, and o-ring from that as it will almost certainly be the same pilot screw. I'm sure it will work. I've done all kinds of crazy frankenbike repairs. I've had yamaha reg/rec on suzuki's etc. as long as it does the same job the bike doesn't care. Considering it's only $20 if it doesn't work you're not out huge amounts of money. From what I gather on the internet the screw should be around 1.5 turns out from LIGHTLY seated. Don't go jihad tightening it in there. As soon as you feel resistance stop! Mark with a marker where the carb screw stopped then turn out 1.5 turns, that should get you close. At least on the 33mm carbs, The 32mm could be different I'll try and find out what the turns on the 32mm's but it should be from 1 1/2 turns to 2 1/2 turns. You could always just mark on another carb where it sits then carefully turn in and count the amount of turns then back it back out to where it was. But I'll try and get some sort of real number as "if it ain't broke don't fix it" if possible. It seems to imply on the microfiche that you use 1 1/2 turns out. Thats probably a good start as the idle mixture is probably identical.
Here is the carb from that crazy bike shop you can use:
http://www.alpha-sports.com/spst/1996%20GSX600F/06.htm
Get parts 34 - 37 Around the same price $20. Not sure of the shipping I'm assuming Singapore is a bit of a swim from BALI.
If you look at the guts of the carbs they are identical as they are the same model but the 600 has an extra 1mm diameter throttle body. Let us know if it works out.
I kind of doubt that the mechanic "forgot"(hope he didn't steal it for another bike) to screw in the mixture screw, if he did start doing your own work!!! It could be that the spring was tired and the screw worked itself loose. Another reason is if the mixture screws were tightened crazily and it half destroyed the threads. Who will be installing this mixture screw? Yourself or the mechanic? If it's your self after you've turned out the mixture screw to 1.5 turns out. Push gently on the mixture screw then release then push. It shouldn't have any play at all. If there is play then the threads are worn/trashed. What I would do then is unscrew the mixture screw completely again and apply some lock-tite BLUE. DO NOT USE THE PERMANANT RED. Apply some of the blue locktite to half of the threads only and screw it back in to the 1.5 turns out. This will give it some resistance when turning but not permanently glue it in there. It should be enough to keep it in there until the bike is dead.

The GS500 uses the same carbs.
You can just cross reference those carbs for parts.
-
Will look at the GS500 carb,thanks for the info.
the dealer in Singapore replied & says Suzuki had those originally capped off so you couldn’t change them and didn’t have a part number for them.
:banghead:
-
On the GS500 carb would these be the parts on the schematic ? Numbers 20-24 http://www.alpha-sports.com/suzuki_parts.htm?gclid=CKPRg_i9oa0CFUZ66wodTUEumQ
-
No schematic. it just opened up the parts pages.
I've used that fische myself for needle o-rings and the like. I know they work.
-
After checking out the part numbers for the GS500,turns out they are exactly the same part number for the GSX600 as mentioned,so now just waiting to order.
Got me wondering now if the carbs are actually original or off another model bike,if the suzuki did actually plug the holes for emission control....
Will let you know when the beast is back on the road.
Thanks for the help & welcoming me back to the forum,even though i have a Kawasaki in the garage now also. :grin:

Some markets are plugged like N. America. And some like Europe and Australia they are open. They also get a nice adjustable needle. I drilled the mixture plugs out the day I got the bike new from the dealership and never looked back. In Canada we get the shit EPA plugs even though motorcycles are exempt from any smog emissions. They also use Canada as a test market for bikes going into the States so we get lucky alot of the times and get bikes first ironically over the States. Or keep bikes that those in the US like to buy. The most similar motorcycle market to Canada is Germany so we keep alot of the cool Euro bikes. You'll see in the States alot of bikes imported from Canada, especially large displacement or rare samples from the '80's when there was a huge tax in the States for over 750cc because Harley Davidson whined to Congress because no one was buying their bikes because they were even shittier than they are now(I know thats hard to believe, but it's true).
They were even offered help by the Japanese big four but turned it down and bitched instead of just improving their products. That and them killing Buell(although probably for the best for Buell)because the Buell "entry level" bikes were blowing away their own bikes and Police Dept's were trying to buy the Buell Ulysses Police bikes instead of the slow-ass unreliable Harley police bikes is why I'll never buy a Harley. I don't want to reward failure and political connections instead of innovation. Really the writing was on the wall when AMF bought the company way back in the late 60's. Harley Davidson effectively ended as a motorcycle company in 1968 when AMF bought them out and they totally abandoned racing when those new fangled Japanese fours and 2 strokes were wiping their ass on the track. Did they pick up their socks and say team up with Ford or GM to create a multi-cylinder bike that would re-establish Harley on the track and teach those new comers with half the monetary resources a lesson they won't forget? Did they start working with their suspension people for better handling? Better brakes? No they packed up and limp dicked it back to the factory and gave up road racing. What phucking pussies!
Now they been reduced to a fashion house relying on aging easy riders which will die out or be too old in a decade or two to ride then where will they be? Stuck with a shitload of slow, bad handling unreliable motorcycles that are too expensive to buy when my Bandit 1200 STOCK for a 1/4 or the price beats their fastest bike the V-ROD. Hell on PINKS(drag race show) a 1982 GS1100 beat the V-rod and the V-rod broke on the third trap run!!!
The funny thing is is the Harley guy who named himself "Hollywood"(just gay) had a whole bunch of attitude and brought a super fancy trailer with a pit crew and an umbrella girl! Hahaha. He was even given a bike length after the first race. His bike was all chromed up with a fancy exhaust and shit and he said it was worth $18000 the guy on the Suzuki probably weighed like 250+Lbs(he was a fat phuck) and his bike was stock except I think he had a four into one(might of been stock can't remember) exhaust and probably a stage 1 max because I saw that he still had the stock airbox. He bought his bike for $2500 used and drove it to work every day. He drove to the track while his wife had a shitty pickup truck with the cheapest ass bike trailer. The best line of the show "Well thats what happens when you bring a Harley to a track" Hahahah. Another guy said when the guy was bitching that his bike was broken: "You should be used to it". Hahaha. He didn't even want the bike, he called to his wife to get the for sale sign out. He then trailered the Harley and drove away on his bike as the Harley had broke it's clutch. I think that sums up the HD rider vs people that are normal.
Buell could have saved Harley's ass because Buell wanted to create a real Motorcycle company. If something was crap he improved it, if it was too heavy he lightened it. He actually was at a minimum keeping up with the Japanese and some of his innovations actually surpassed them, especially his novel braking system. Despite using the shit Harley engine, he got as much power as possible out of them and improved reliability and they proof is in the pudding because there is still a shitload of Buells on the road and my friend built one from parts and it's one awsome machine. Thank god Buell is back with his Eric Buell racing or EBR bikes. He's putting out a super bike now in limited numbers to gain capital but he will be making mainstream bikes. If I can afford one I'll buy it because I want him to succeed and I guarantee you it will be an awesome bike considering he's using ROTAX engines now.
I was trying to get the link to the U-Tube video of that PINKS drag race it used to be all over the internet but has suddenly disappeared I wonder why????? Someone or some company wouldn't have complained would they??
Here's my friends he built from scratch out of parts he got on the internet at the back of his shop:
