OMG fuel taps

[rossclark]

I've broken two OMG fuel taps today, the plastic cone bit that turns the tap on and off. Someone said there was an alloy replacement available for this part - anyone know who supplies it?

Chiggy at Lambretta upgrades?

Perfect Norrie, cheers

Oh they look good, getting one of them.

[HxPaul]

It begs the question,why dont they fit these new,after all in my opinion OMG are the best taps you can get............apart from this obvious fault.

[Scooterdude]

Wow, i never knew they existed, ive got a bust one here so will be ordering one.

[rossclark]

I had to buy a new tap yesterday at a local dealer and opted for the Scootopia one but the dealer also showed me a different all alloy OMG one, which I now wish I had bought, as I had to drain the tank again because the Scootopia one was running about 150mls a minute ... I'd filled the tank and it took over an hour to drain it...

On dismantling the tap I found that the inner plate with the tree holes in was rotated partially occluding the holes. Turned it round, reassembled and it flows 500ml in 49s - just goes to show how little it takes to cut the fuel flow to next to nothing

“Occluding” Great word use

Result, I’ll be getting a few of them

My English teacher said I'd never do any good...

has anyone compared the flow rates on Scootopia/OMG/Others??

which is the fastest flowing?

[rossclark]

The OMG I took out (and subsequently broke) was flowing about 600ml in a minute so probably comparable to the Scootopia one I put in.

The reason I took it out in the first place was that there were some gritty rust particles appearing in the float bowl and when I took it out there were quite a few flakes around the filter on the tap. Exactly the sort of thing you'd expect to find caught by the filter.

I'd been having an odd symptom on a couple of runs recently which initially I thought was a soft seize but now actually think was a fuel starvation issue. After a run at WOT I'd get the blaaaaa sound, I'd whip in the clutch and shut the throttle, it would then race like it had an air leak for a second or two then settle back down to a tick over after which it would carry on as if nothing had happened.

My thinking here is that something stopped the flow from the tank, the bowl empties, engine is starved of petrol, after I declutch a little fuel gets in and it's very lean until the bowl fills then it goes back to normal.

Just done the Celtic Dash with the new tap in and no sign of the problem either day.

One of the scootering magazines had this is the latest issue, can't remember which was it was though, I'll check when back home and post the results but iirc the OMG tap was best overall. I think the Scootopia one was good with full tank but flow rate dropped significantly once you hit reserve

[ToBoldlyGo]

It would. The reserve on the Scootopia tap is very small.

1/3rd of a litre, i checked.

.... I think the Scootopia one was good with full tank but flow rate dropped significantly once you hit reserve

Speaking as someone who has a Scootopia tap on a TS1 and who always, when he turns the petrol on, turns it all the way down to reserve, this has me very worried. Effectively, what is being said is that my flow will drop significantly at a moment’s notice when I go on to reserve.

I really must check flow rates as a matter of urgency on full and on reserve.

Edit:

Scootopia’s website does say “Fast flow tap with fast flow reserve.”

[burnside]

Sorry it was in Classic Scooterist magazine and not Scootering, also it wasn't the flow that was the issue with the Scootopia it was the low reserve volume. These were the results;

OMG Standard

Full tank - 290ml per minute
Half tank - 240ml per minute
Reserve (2 litres) - 200ml per minute

OMG Fast flow

Full tank - 550ml per minute
Half tank - 440ml per minute
Reserve (2 litres) - 430ml per minute

Scootopia Fast flow

Full tank - 585ml per minute
Half tank - 480ml per minute
Reserve (220ml) - no flow rate given....probably because not enough fuel left

[Norrie Bodge]

Thanks burnside m8, great info

I’m using Scootopia taps in both my bikes

[Storkfoot]

Yes, thanks for the information. I am definitely going to check the flow rate though as I sometimes think I am too trusting in the blurb that accompanies products.
