Hi all,
Got my first bandit and it's a 12, comfortable enough and decent enough on petrol. Tho it brakes ok'ish and handles'ish. Just has it dyno'ed at Steve Jordan, 106.94bhp at the fly. Had it dyno'ed because it's spitting back and filling the airbox drain with petrol, the air/fuel mixture came up perfect tho. They have told me to remove the pair valve because this could well throw the reading out which I can understand. When I bought the bike was on stock suspension on the softest settings, the geeza weighed at least 16stone! Anyway I've wound the front pre-load all the way in and it's still too soft (i'm 12-13stone). Put a ziptie round and it's almost bottoming out. Was thinking fresh oil but also curious to know what the stock spring weight is and if there's another harder spring available. The back in on 2nd to hardest/highest selling and seems on but the back is a bit skittish. My rear brake is pretty damn good, my front is well.... it works but the level feel is crap. Got aftermarket levers and it won't adjust to be good enough. Tried new pads which are highly recommended for 6pot calipers, rebuild the M/C, braided lines and bled twice. With the lever at the right distance for my hand, under normal braking it's fine but it's spongy and I can imagine under emergency conditions the lever will his the bar. Now i'm looking at the calipers but I don't see how this will make a difference if any?
Sorry it's late probably a few spelling mistakes ha, cheers

What are you asking exactly ? If the front brake feel spongy i would say it needs rebleeding, Have you tried reverse bleeding it from the caliper using a large syringe? Ive got 6 pot tokico,s on my Bandit 12 with shorty aftermarket levers and my brakes a really good. Cant help with the front end as ive fitted gsxr USD,s on mine. Heres a link to setting up suspension on motorcycles..... www.gostar-racing.com/club/motorcycle_suspension_set-up.htm#Setting%20your%20bike%20up

The PAIR valve adds air to the exhaust gas to burn off unburnt fuel, so it can alter the gas analyser readings. The Bandits are set up soft as standard, old suspension losses it's damping - the shock didn't have much re-bound damping to start off with - fit a newer shock from a sports bike, there have been threads on here, or buy a Hyper pro/Nitron etc shock and the rear end will be transformed. The front end can be helped by fitting stiffer springs, for the road, progressive springs work well. As for brakes - as Antiks - if you've got originals hoses, change them to braided. Clean discs with brake cleaner/thinners etc to get oil film of - go over the surface of the pads with coarse sandpaper/wet n dry to get a clean surface and they have to work !

It was the rage at one time to fit 6 pots to anything Suzuki but most ended up complaining of poor performance and / or feel. Its a whole system so you have to change the master as well to equal out the pressures! Soft, soggy Blandit - sounds about normal, they were a 'budget' bike after all.................welcome to Bike Modification 101

Was looking for some ideas for my brakes and suspension. I think i'm right in saying the 6pots on my bandit are the same as what was on my zx7r and them brakes were spot on! Haven't tried reverse bleeding before so maybe that's a shout, I just can't work out what else it could be. I've done the lines, MC and fluid. Literally first bit of travel 2cm? does next to naff all then it grabs and stops.
With the front suspension where can I buy uprated springs? Does anyone know what Lb/Kg rating comes as standard?... i will search info about the rear shock.

Had it dyno'ed because it's spitting back and filling the airbox drain with petrol The only thing I know to cause that is flooding - meaning either floats are incorrectly set, or more commonly needle float valves are leaking. I'd be surprised if anything done on the dyno would stop that, but interested to know if it cured it.

But couldn't imagine someone stupid enough to change the pilot jets for the wrong item on a stock bike. They didn't do anything but say they could tweak and mixture screws but I've done that myself and it's running pretty much fine performance wise just overfuelling a little low down imo.

I don't know the standard pilot size jets, but that info could be easily obtained. FYI I have a standard set up except for a Remus end can. I run mixture screws on 2.5 turns out, balance the carbs say every 3000 miles. She runs like a sewing machine. The only overfueling I had was caused by poor sh1te waste of space aftermarket needle valves (quel shock), now sorted with OEMs.

The only overfueling I had was caused by poor sh1te waste of space aftermarket needle valves (quel shock), now sorted with OEMs. My setup sounds much like yours with an endcan also. When I first discovered the problem I did balance the carbs the best I could and it runs as I say pretty good, with a bit of what it seems overfuelling. The screws should be about the same as yours however mine are all over the place and even trying to get them approx 2.5turns out was a joke the bike wouldn't run. (couple of mine are about 2turns and 4/5 on the others). Like said runs well and fuelling on dyno seems spot on but 5turns out isn't right at all. Seeing as performance is ok, first comes up in first reasonably ok I was going to focus on sorting the suspension and front brake first as I ride quite hard and it's a bit skittish. I will upload the dyno sheet later.

If you're going to have to change jets and screws I would connect the carbs up to a remote tank....if they start leaking it's the needle floats - that caused my over fueling. Itsa simple test, DEMON TWEEKS do a rremote tank. Leave the fuel loaded overnight and check the level in the tank.
if it was me I'd check / replace with correct pilots and set the screws (easier with carbs out).

Oh...btw balance at 2000rpm....someone on here suggestex that. ...I got a perfect synch when I did that, never quite managed it at the 1400rpm I used to balance at.
Which part of the country are you?

Suzuki recommend balancing the carbs at 2000 rpm.

For your rear end I'd suggest a GSXR1000K7 shock, easy fit with washers to open the dog bones up and a little mod to the original undertray. Put one in my B6 a few weeks ago and it's a revelation!!!!!!!!!
