[Fuel return for turbo bandit]

Hey B12Mick, where in the fuel supply chain does this go? It looks like it mounts right onto where the fuel tap would normally go.

Do you sacrifice reserve using it? 

Saw this, Its a dual feed however could one be used as return?

Thanks

Thanks for the responses, I'm looking at that tap, trying to work out how it comes back into the tank higher than leaving. Is it that tall rod that sits in the tank above fuel level?

Hi all I'm in the process of working out the turbo system for my mk1 Bandit. 

I'm curious as to what people have done for a fuel return system on these. 

Can you please provide some pointers/ideas? 

Thanks!

Thanks for your advice gents

the bike still runs a tad rich on th3 ifle circuit, so a dabble with the a/f screws should resolve that

[Mk1 Bandit 600 carb troubles]

Plugs are CR9EK, carbs balanced as well as can be done. Tappets were done not long ago

so put in the dj100 jets, set needle heights back to standard, it runs alot better. Still a bit bubbly at just on throttle, but, it's definitely a lot better. 

I have noticed that one of the plug holes does seem to be threaded, whats the best way to repair this? 

[Mk1 Bandit 600 carb troubles]

Thanks WSN, 

So, a bit more testing. A/f screws at 2.1/4 turns, slightly snatchy throttle.

Set at 2.5, less to zero snatch, but bike felt a bit lumbery (too rich)

set at 2 turns, very snatchy, less lumbery, but the snatch is dangerous mid corner. 

I'm thinking, despite dynojet suggesting DJ104 jets for my setup, im going to test with DJ100s. As it feels too rich potentially.

Thanks dude, I'll investigate further

That's an impressive turbo setup! Tha ks for serring me straight, it makes complete sense when you put it like that

[Turbo placement.]

Well, one of the turbos in a compoind freds the other, so the drop in efficiency may not be as pronounced as if there were a single turbo setup.

Maybe having a compound turbo setup would solve the possible low efficiency of turbo, also exhaust wrap is meant to keep the heat in the pipes a bit better isnt it?

[Mk1 Bandit 600 carb troubles]

I did think about the carbtune balancer.

Maybe a Christmas present to me!! Hahaha! 

So after some testing, there is still a very narrow part of the throttle range where it's lumpy. This is at just cracked throttle, so for bimbling around town.

The throttle is also quite snatchy down there. So some fine tuning is needed, however some advice on what might cause the snatch is appreciated

my thoughts are that it's too rich down in the idle area still, I have my secondary airbox hole covered currently, so thats the next test

[Mk1 Bandit 600 carb troubles]

Apologies, lifted needle clip position... Dropped the needle down.

[Mk1 Bandit 600 carb troubles]

Afternoon wsn, so took carbs off and setup a remote tank, and there are no leaks.

So far this is what I've done and it feels better. 

Lifted needles by a clip position (leaner) 

Reset a/f mixture to 2.1/4 as suggested by dynojet. 

Balanced the carbs by eye while they were off.

Bike idles really well now. Hunting is near enough gone, it actually idles instead of constantly nearly cutting out. I do have some high speed runs to test as well. 

[Mk1 Bandit 600 carb troubles]

 

By needle float valves, do you mean this little ali parts with the rubber tips that seat when the float closes? 

Tell you what, thats one thing I didnt do, I have a remote tank and I've had the carbs off loads.

Thats something to try, my airbox is dry though

[Mk1 Bandit 600 carb troubles]

Hi Gents,

Short story time!

I have a mk1 bandit 600, I'm having issues with the carbs, still. 

The mods on the bike are as follows:

Dynojet stage 1 kit
DJ104 jets
Simota Filter
airbox mode 44mm hole - Currently covered for testing.
Full blackwidow system with a full length can
dyna coils
4 degree Ignition advancer

I set the carbs to the default settings for dynojet kit, 2.1/4 A/F screws and e-clip on position 4 on the needle. larger DJ104 needles as I have a full system and free flowing filter. I have altered the float heights to 18mm from the standard 17mm to try and reduce richness, however this hasn't helped! (intentionally tested at 16mm and found to increase richness severely)

I've had a Mk1 B6 before with the same mods, except a standard system, that was the same settings on the needles, didn't check the jets. and it ran absolutely amazingly. even compared to another mk1 I rode at the time. 

I'm tapping into some wisdom here to see if there's anything I've overlooked?

Edited to add the actual problem I'm having...That helps! 

when I first start riding the bike is sweet as hell, pulls hard doesn't stumble, it's great! however on an extended run of low rpm bimbling combined with full throttle full rev testing, I come across what feels like almost flooding cylinders, revs will sit high, like around 2k for a while on idle, I leave the bike for a couple of hours, come to start it again and it's fine. Coming onto the power from low RPM results in a flooding stumbling feeling. I have stripped and cleaned the carbs a few times now to ensure everything is clean. I've also balanced the carbs after each strip and rebuild.

I think there's a slight scent of petrol in the oil as well. 

I have yet to do a compression test.

Thanks guys!

Hey guys I'm back after a very long absence of owning a new vehicle in the shape of a k3 gsxr 1000, the was knicked, insurance underpaid so I now have a bandit 600 until premiums go down

so far I have fitted dynacoils, iggy advancer, stage 1 kit and a temporary hiflo filter while I source a K&N one. I have a full system to go on, them exhaust bolts though....

I've also replaced the caliper seals and head bearings  it feels like a new bike from that work!
