I'm really used to having a longer range on my bikes and the result is that I've ran out of petrol twice on my HUSKY without the fuel light coming on. Both times I was saved by opening the taps on both bottom sides of the tank. I'm not even sure exactly what they're for, but I just assume they're a sort of "reserve" like I had on my dirt bikes. Then I had to stand a while (assuming the fuel needs to run through the pipes?) before she would fire up again... So a few questions, as this is all new to me: 1. I'm assuming that there's some sort of plug/wire/sensor that's not working or plugged out. I haven't lifted the tank to have a look, but will do do so when I get a gap. 2. Can anybody tell me if and how those taps are related? 3. Both times I was on around 150 - 160 km and the bike took around 11 litres of fuel. Can that be right? Am I only getting 14km/litre? It seems very low for a 600 cc EFI single. Is it the "Power Up" mod that screws up the consumption this badly? 4. I've made an inquiry about the Safari tanks which will extend my fuel range from 160 km to 350 km, which is a decent (and almost required) distance for an adventure bike on trips The tanks look good and I'm sure they're worth it, but the price is a bit steep...
Those taps should both be open all the time. I use a Nomad rear 'bum tank' when I need extra fuel. I have avoided the big Safari as I do not want the bulk up front and for me it will overwhelm the front end and effect the great handling.
I did an out and back ride in the bush the other day in my 630. At the out leg which is 100 Kms I put in 3.6 litres. I was riding through bush tracks, fire trails snow across the top of mount buffalo and 210% tarmac. I think you need to review your fuel consumption, must be running way too rich.
In the 'mountain kingdom' of Lesotho, Southern Africa - fuel is few and far between at times and did not need more than this Nomad tank.
Arch I realise now you are a fellow Saafrikan (I will not answer your question again on our Wild Dog forum).
