How much alcohol to use in tank?

[spencer_foxwell]

Morning gents, I've got some of this and just need to know how much to put into a full tank of fuel to stop carb icing and such? Oh and this is the right stuff yeah?

Cheers

Never seen anyone do that in a fazer. I dont fazers are prone to it anyway, only sports bikes with direct ram air intakes ---ours faces backwards and is under our arse low down sort of behind the engine where all the engine heat gets blown back to the air filter box so no issues

[Gnasher]

 A lot of mid 80's on bikes are prone to icing these bikes have heating systems (water or electrical) fitted as standard to over come the issue, the Fazer has such a system.  If you look at the carbs you will notice small black pipes going into to even smaller polished elbows this is the heating system.  Due to insufficient anti freeze mixture or poor quality anti freeze these and other small galleries are prone to blocking and therefore stop the system working, if you search the board myself and others have posted how to sort the issue.
 
Basically you dont need anti freezing additives just fix the heater system.

The Fazer's can be prone to it if the carb heating circuit fails

Pretty certain Darrsi uses this a lot and I used it early in the year on mine just to bind with any water that may or may not have been in the tank. Pretty sure I used about 250ml for a full tank of fuel? There was a fuel additives thread in the 600 section that had more info

Looks like I was wrong then --- it does happen on our bikes, or rather it can.

But only due to system failure, so you was right!
I occasionally use pro fst as it helps clean away any deposits that have formed in the fuel system

[spencer_foxwell]

I was under the impression that this alcohol does the same thing as that FST but is cheaper?

Yes it probably will, I was just stating what I've used in the past and why!

[chaz]

put half in the tank and drink the rest?

[Ianboydsnr]

Should only need 1 percent, try that then see if it works, if not add another percent, 1% of 15 litres, is 0.15 litres, so about a quarter of a half pint glass, don't fill it up and drink it down to that level though 

[spencer_foxwell]

I've probably put 150-200ml in so we'll see if it starts in the morning too

Well, I could be wrong but I don't see those pipes on my carbs. Could the 400 be different in that respect?

[unfazed]

They are there just in a different place. Look in between the Carb and the cylinder head and there should be a pipe coming from the float area of the carburettor. The should be one on both sides of the bike. The pipe on the left goes to the left side of the thermostat housing and the one on the right goes to the right side of the radiator below the large coolant pipe.

[spencer_foxwell]

Just looking at a picture, I do see the smaller pipe bellow the larger pipe on the right of the rad

To be fair I haven't had any icing issues since I changed the coolant out and gave it some radflush but I wanted to cover my arse as much as possible. Apparently it also helps with cold morning starts so worth a try anyway

Yeah, its just one of those things - the model itself doesn't seem overly susceptible but a few of them have been known to get it and suffer more so than others. I had some carb icing back in September - it was just one of those nights where the temperatures and humidity were at the right levels for it to be absolutely perfect conditions and my 600 isn't in the best of conditions. The result was being stuck at the roadside for a quarter hour, waiting for the ice to melt 

Unfortunately, I didn't have any of the alcohol and hadn't been using it as it was an unexpected journey which I had to make.

[locksmith]

Blimey, the things you rufty tufty all year bikers have to put up with

[Dead Eye]

I would have taken the car... but it likes to drink more than twice the amount of fuel which made the journey somewhat more financially problematic as it wasn't just down the road haha :P

[spencer_foxwell]

The bike started pretty easily today so I guess it helped

[JZS 600]

I had loads in the tank last night but luckily I got the train home


Go Camden!

Have ridden in zero temps on my fazer without any issue ...., but that was up the grimsell pass in high summer !......snow, ice, blizzard winds...all part of a swiss summer !
 
yet on another trip, 3 yrs before, it was 25 degrees at same spot. Dont ya just luv the alps ??

[Streetbudgie]

My 2002 foxeye carb iced every winter from new to last year when I part exchanged it.

FST Pro sorted it every time and it was no bother, cap full in the tank after every fill up and no more carb icing, preserves the pistons and rings as well apparently.

[spencer_foxwell]

It was pretty cold this morning and would have iced for sure if I wasn't using this alcohol. It didn't start though I had to bump it :/ I think I may have another issue there...

[unfazed]

Check for air leaks then check the valve clearances and balance the carburettors
