[Group] SUZUKI Bandit

[swirlacer]

i think he has the 400cc one.so engine wise not compatible dude.

[Frank y]

Thx swirlacer, ...sigh...not easy finding a manual for my bike.

[swirlacer]

haha...as i have posted somewhr, go to tradebit.com to find it.u must pay though. oso, GOOGLE it. really it works. no,not scan thru 5 pages, go thru until u exhaust the search engine. be it that the site comes in different languages, u just might find ur manual. how i know? caz my bike is super ulu CAN>? ever heard of suzuki gsx400fws? at least urs is more current. mine is like 1984? Ulu-est bike ever. go over hump will ee or ee or one. the sound of squeaky rear suspension is music to my ears..haha...

Thx swirlacer, for tradebit.com reference.

 

Yes, I know the gsx400fwx. I've ridden with a gs400/gs550 group in 1978 with my TS185S. I later owned a CB400N in early 1981(mine was one of the first two of the 1st 5 CB-Ns in S'pore: three were 250s, two were 400s) I followed the gs/gsx for a while because I was considering the 400 class. After the gs400e(twin) came 425(twin), then 450(twin - which didn't come to S'pore). After that came the 4 cylinders gsx (with the more flowing tank to sidebox styling - I think it's the white with blue stripes that was more common then). My cousin used to own a gsx400fw....oops.....did I just disclose my age?

 

This is what I can recall from memory.

[swirlacer]

haha....cool that u noe my bike. i tot its damn ulu. i'm getting used to the little niggles, things like dying off while idling...blar blar...nice bike to ride. yup original colour is white with blue stripe. so have u found it?

[danielburgess]

Been looking through the wiring diagram, hehe, and getting some ideas, like several warning lights.

 

1) Sidestand.

2) Left and right signal warning light (Bandit only has a turn warning light)

 

Cheers!

i believe ones u understand the current circuit u can make another so u have one for each direction.

Alamak! That's almost like saying I'm damn ulu:lol: .

 

Anyway, saw your carburetor problem on vintage/classic. I think you have to find out what your vacuum tube does on your carburetor. I'm not sure about bikes, but I know quite a bit on carburetor for cars. I've learnt to disassemble/assemble/overhaul Weber carburetors(DCNF downdraughts-still got 4 pieces at home, I think. Also some DCOEs and Dellortos), but that was 10 years ago.

 

Though I've not seen your carburetor, I suspect your diaphragm mechanism acts as an automatic pneumatic overchoking or antiflooding device during engine warm-up operation. If your diaphragm connects to your choke and the airtube is tapped near the throttle valve, I'm pretty sure that's what it does.

 

If you don't have this diaphragm, no suction means the return spring in the mechanism will act and close the choke a little bit more(even when you've released the choke), meaning richer air/fuel mixture.

 

I could be wrong of course as I've not seen your bike. Can I presume that you've overhauled your carbs? You should probably have done that first, but must make sure you have an overhaul kit, carb manual, float clearance, etc. prepared beforehand.

[danielburgess]

Just did some work on the bandit today, servicing and such. Took all the connections out and wiped all the deposits off as the electrical system has been a little jumpy lately, also placed a new battery in. If I have the time might get some oil and do an oil change later tonight.

 

Cheers!

[swirlacer]

hey frank y, i dun think i can find a replacement kit for the carbs easily. haha...old bike la. anyway, the carbs been cleaned throughly. everything works well cept when the fuel tank and tubes go on. we then isolated the problem to the vacumn tube. once we connect the tube to the fuel ****'s vacumn outlet, it dies off.(with setting at ON or RES) damn hard to start after tt. the choke has nothing to do with it.

now, i may try to check for air leaks in the carb manifolds.-possible problem to unstable idling. mabbe u could give me a hand?haha...i do have the service manual.

Gasket material of different thickness can be bought in sheets and cut-to-size. You need patience when using the carb body as a template for drawing/cutting. The round gaskets take a bit of searching as it is better to bring the original to a spare-parts shop for reference.

 

Jets only need to be cleaned to remove any gunk, but don't use needles to poke into holes - these are soft brass and may end up being enlarged, you may end up with a different jet size because of this enlargement. And yes, you can detect changes when different jet sizes are changed, but this requires the availability of a whole range of jet sizes and OTR testing (very tedious and time-consuming). But since you are using original engine/carbs, better stick to not damaging/changing anything.

 

I don't know about this fuel kok's vacuum outlet cos I've never heard of a fuel kok with a vacuum outlet. What's its function? Is it for fuel overflow or fumes extraction from the tank? If it is, could you have plugged it into the wrong place? Or maybe don't plug it in at all? As I've said, my carb experience is with cars not bikes, also that you must know what those vacuum connections are for, then will you be able to modify them to make it work. What does your carb manual say?

 

Vacuum connections on carbs, for cars, are usually tapped from the inlet manifold. How will you be checking for leaks? For cars, I check inlet manifold(made of cast iron, but I think yours are hard rubber) leaks by carefully applying a tiny amount of fuel at the mating surfaces of carb and manifold. The engine-note will change(usually rpm increase). But if your manifold between carb and engine is hard rubber, fuel will in time harden it. Anyway, this method is hazardous for bikes cos it's closer to the hot engine and it is fuel we are playing with.

 

I think it's great you're doing all these stuff. For me, it WAS enjoyable and informative, giving me confidence and knowledge in self-repair (I overhauled other car parts myself too - brake pumps/calipers, ac gen, camshaft/cam belt change/adjustment, etc.). It gives me confidence to drive/ride into Malaysia myself or with my family in the car, so long as there's spare parts available.

 

And no, I won't help because it WAS enjoyable, and I stopped enjoying getting 'high' when using petrol to strip/clean/overhaul the carbs:giddy: :lol: . Also, I only do it as a hobby/to learn/save money, it is not my occupation, though I used to repair fighter jetplanes.

 

Anyway, fun in having a vintage vehicle means 'fun' in trying to get it in working order as much as possible. Well, it's your 'fun' time:lol: . The greatest thrill for me is when it got onto the road feeling 'right'. All the best to your effort.

 

Haiz, I'm so long-winded:) .

[swirlacer]

haha...yes, i meant to check for leaks tt way... but using wD-40. haha..yes, i understand the WAS part. it becomes mundane after awhile. i got a spare carb(95%similarity)..so most prob i will look into it to find replacements. and no, ur not long winded..ur info helps me to understand the carbs thingy.

[danielburgess]

we can all agree that carbs are really b|tchy things...

[swirlacer]

i think carbs are quite fool proof things if u worked on it once or twice. but to troubleshoot a bike with fueling problems is really a *****. wahaha...now my bike's average running temp is 100 degress celcius...120 is High on my old speedo's thermostat. siao liaoz...haha...

[axn85]

guys... i oso have a problem with my bandit 400... when riding is not a problem... but when i engaged neutral gear at red light... the engine suddenly just die off... den its sometime easy to start... sometime cannot even start... this has been going on for a few months already...

 

recently... i have tired to stop with gear 1( pulling the Clutch) but the engine will idle for awhile before dieing off...

 

i have done valve clearance in march... change the carb last 2 months ago... sprak plugs last weeks...

 

can anyone tell me wat is wrong with my bike PLEASE...

[danielburgess]

I have the same problem as you. I suspect it is electrical. You might have to change your rectifier to a new one.

 

Cheers!

cld be...batt flat not charging. If there is a hissing sound cld be one of yar carb vacumn cap came off.

Hello, I'm letting go my Bandit 656 2005,.

[C.S]

hi

seems like i got a lot to learn from here

yea, to danielB, i got a slightly cheaper Bandit 400, cos on budget

hope to meet and learn from u guys pretty soon

[swirlacer]

so who did u get ur bandit from? welcome to the bandit forum-even though i dun ride a bandit. haha....try to check ur batt charging status using a multimeter lor...might be alternator oso..not neccessary rectifier. good luck troubleshooting the bike...update us yea?

oh

i got it from some1 who rarely post on SBF

his real name is sean, but dunno his nick

anyway

it was a quick or u can say hasty decision

nonetheless, beginning to enjoy the ride, after 2 yrs + of 2B bike,

 

for a noob, i have this Q

this morning, the blardy weather was raining like crap

i had problem starting the bike

cranking ok, but idling keeps dying on neutral

then when finally idling seems to be rather stable but not so stable, gear1, engine died again

had no choice but to keep small throttle to keep the idling going, but after like a few KM of riding, everything back to normal

any idea wat happened?

Ya its happen 2 mi when i was riding a gsxr 400 K model. When i applied e brakes harder in traffic lite 2 a suddenly stop, e bike will stall oso. Mayb u wanna adjust ur idle rpm higher a bit c whether will solve ur stalling problem? If not most likely ur bike carbs may need a wash n tuning. Old bike like tat 1, cold engine need a slightly higher rpm 2 substain idling until e engine reach it's operating temp, then everything is ok. Try e costless method 1st, if cannot then maybe u wanna opt 4 e cost method?

[Gh0st _R11der]

gurumachaz the bandit 650 is a k5...k7 is something to look forward to. But dunno if anyone going to bring in the k7

 

Yap, K7 summore FI n a new liquid-cooled engine, metallic graphite blue looks great esp e S ver! It will cause a concern whether this model will b in sg due 2 e fact tat ters oledi GSR 600 variant. But if u ask mi, i'm still upz 4 e K7 lah (old-school rider?)

yep, thanks,

will want to try turning up the idling

but dunno which screw

will go trial and error tml
