Bandit 600 running badly...

Hi, just bought a '99 bandit 600, took it for a test ride and all was fine, was told it had been standing for a year previous so got it home and it seemed to be low on electrical power on start up so bought a new battery, and that solved the power issue. Now it's sluggish on start up as in takes a few goes to start it (it attempts to turn over ok) and now when I take it for a run it goes a bit then cuts out and dies when I open the throttle. I tweeked with the idle valve and it makes the bike Rev a lot and tick over better but still cuts out when I take it out when I open the throttle? When I opened the mixture plugs petrol started coming out along with a little brown liquid then all petrol so I dunno if I was doing it right?

I've took out the spark plugs and they are all wet and black so I'm guessing it's running rich...

I'm new to bikes so I've literally only been going off the websites about this but I'm not confident enough to take off the carbs to clean them.

Anyone know the easiest way to sort
This out? Ive booked it into a garage next week but if I could
FIx it myself I would save £150

I know this question will make me sound like a total noobie so any advise would Be great thanks

Where abouts are you based?

Does sound like carbs really, if you are local enough ill happily come over and provide tools and guidance.

I'm in Sunderland? I would much prefer something with a hand from someone off here instead of taking it to the garage and paying

Don't make the mistake I've seen over a million times and rush it Wink

What's the air filter like?

Genuine(?) mileage?

General condition?

A little far from me buddy, shame!

I'm sure someone on here would be happy to assist but I can assure you, it really is as simple as removing the bank of carbs, undoing each bowl one at a time and cleaning them, removing the jets etc.

I would recommend removing the cables from the throttle rather than the carbs as they can be a pain to get back in.

If you are scared to strip and clean, you could post them and I'll do them for you. It really is quite simple Thumbs Up

In reality, it won't be far different from this - https://www.youtube.com/watch?v=IdCL9DoBTo0

You'll notice minor differences but the main thing is cleaning the jets and bowls properly. Any dirt is likely to affect it.

Air filter is definitely worth a look at, however I've never liked the space constraints on the Bandit Laughing

I think I'll bite the bullet and take it to the garage, I managed to tinker with it earlier and took the air box and tank off but knowing my luck I'll break something and have to call the garage to fix my mess up ha

The spark plugs are something I could do myself but I've read up on them and it says the bike is running rich so I'm wondering if I change the spark plugs how do I stop the new ones going the same way? Ie black and covered in petrol?

I would definitely give it a go. You'll feel more satisfied Thumbs Up

I wouldn't pay too much attention to the state of the plugs for now. if you're keeping the bike, deffo replace them though. Did you get rid of any old fuel?

As Paddy says, it's no big deal to just clean the pilot jets. Get the carbs onto a nice clean rag and take each bowl off methodically, sticking all screws etc in a dish/pot.

FFS, be careful where you take the bike if you go that route, only use a garage that's recommended Thumbs Up

my first "proper" bike was my Bandit, taking the carbs off is straight forward

Take seat off
take tank off (2 10mm bolts)
undue all the jubilee clamps on the airbox (back of carbs)
undue all the jubilee clamps on the inlets (front of carbs)

open the carbs with your hand (sounds complicated - move the throttle) unclip the push cable

with the carbs closed you should be able to release the 2nd throttle cable now...

take the choke cable off

push down on all the carbs - they will come off with a "pop"

careful which way you hold them as some fuel may come out

now use pete's guide on how to clean em - which funnily enough is on Bandit carbs

first time it took me about an hour to get the carbs off - an im an oaf[/url]

Hi

Got your PM unfortunately I'm quite busy at present trying to sort my own stuff otherwise would have offered a hand.

What Mudcow suggests is pretty much spot on, I've done the rig ma role of carbs on and off Bandit 600's too many times they really are temperamental.

First suggestion is as others, give the carbs a clean following the removal method, be careful with the float bowl cross head screws, many a time these get chewed up by some moron and re-used rather than replaced, make sure you have a good nick posi screw driver and consider some plus gas penetrating oil before attempting them.

Whilst your in there cleaning the carbs you may as well check the float heights too (should be 17.00 + 1.00 mm) but you'll need a feeler gauge for that. (little vid of how to do that check once you have the float bowl off in case you don't know how https://www.youtube.com/watch?v=Rj52oUY7ISc).
