Howdy,anyone had any experience using Harleys idle boost fluid and what is it exactly and how does it work?

I'm from Tassie and ride in any conditions and occasionly in certain freezing conditions my 01 dyna wideglide ( stock cv modified ,engine stock,pro pipe 2 into 1)

plays up a lot when slowing to town speed limits after highway speeds.

It has been explained to me that carby freezing happens when moisture from the air being sucked in freezes around the main jet needle causing an interuption

to the fuel supply. If the bike stalls and is left for a few seconds the heat from the engine dissapates the frozen droplets and the bike will run ok again and may not

do it again as the day warms up.

Any feedback much appreciated

Can't help with the "idle fluid" mate sorry

But can recall a trip as a young man from Scotland to London ( 800 K's !) where my old 1200cc 4 cylinder Opel Kadett was "konking out" at 70MPH on the motorway ( that's around 110Km/H ). Air temp in January around -4 C

OK below that ? Coast to a halt on the hard shoulder , car would start and drive away no worries ?

After the 10th time or more , I coast to a halt and whip off the air filter cover and fuck me there's a " snowball " in the carby throat !!
As I watch it "melts" away with the residual heat from the engine. Continue the rest of my journey at 55 MPH ( fucking slow !!)

Get to my destination , into my toolbox , into the shed and a wee bit of heater flexi-hose wedgeid onto the air intake running to the exhaust manifold to draw "hot' air . It froze for a month that winter in the UK , went to -16 at midnight with -4 at midday !!

No more dramas from carby freezing for me thankfully

Chances are your freeflow air cleaner is allowing too much "cool" air thru ( which is the whole fucking idea of course !). Some of the 1340 Evo Harleys suck the air from the cylinder side of the airbox , not the front. Maybe a temporary / for the winter mod to air intake ?

 Thanks retro man and  kiwi dave, the info on the pommie website has explained everything perfectly,thanks very much.

I think i will try a Mikuni 42 when finances are available. cheers

Probably easier than adding alcohol to your tank, maybe try some E10 ethanol.

the E10 idea is a good thing, but if you do park the bike for a few days empty the tank and run some normal petrol thru it, as anything alcohol biased attracts moisture and if left sitting will start to cause corrosion in the tank, carby etc. it can cause a big mess if left for long periods of time.

T1 Your right of course, and I doubt adding Alcohol or using Ethanol would actually work anyway.
Maybe just try mixing a few litres of E10 per tank.

 Yeh there may be some merit in what you both say about e10 as far as the alcohol side goes and the winter idle boost is just alcohol really,therefore boosting the octane abit i suppose.

On the english forum one bloke reckoned the idle boost just allows the fuel to wash off the frozen moisture in the carb.

 

when the weather is that cold, keep a bottle of jonnie Walker Red in your saddle bag, one cap for the fuel tank,,, and ya just never know what the rest might come in handy for,,,
