Gutting fuel tap

Post by reverse cylinder jim » Sat Jan 01, 2011 4:40 pm

Hi all ive heard a few people have done this and wondered what the benefits were if any?
Do you just gutt the fuel tap so there is no need for the vacuum hose? Is it a good idea to run a dry break coupling to aid tank removal.
Thanks James

only benift is that you never have a problem with vacuum hose kinking, pulling off etc, its a reasurance that you WILL always have petrol flowing.

HOWEVER

you need to remember to turn the tap off when stopping the bike and on when riding. otherwise youll come back to a bike thats pissed its self, happened to me once and im still debating going back to having a vacuum hose again.

As far as I known the idea was to not restrict fuel flow when riding at track speeds, if you do a trackday or if you race once you up the pace you will notice a slight delay in the power delivery. (I think the HRC manuel said do it as part of your race prep..)

I found this to be worse coming out of mid speed left handers after heavy breaking, it was never enough for me to mod the tap mainly as I really didn't want to walk into a garage full of petrol where I have left the tap on over night..

I would stick with the vacuum hose to be honest, and if the bike has been stood for any lengh of time take the tap apart and give the internals a good clean otherwise you may find it sticks shut and you will be pushing the bike home due to petrol starvation :whistle: (Dont ask :grin: )

Thankyou for your replies.
I should have said that my bike is track only. So it will aid fuel flow for when i start extracting more power from the bike.
I will just have to be careful and remember to turn off the tap after use.

Do not rely on turning the tap off, get a dry break connector mate.

Sorry, but whats a dry break connector?

I did the fuel tap conversion a little while ago, and noticed that I now have a major fuel leak :(
Trying to source up a new fuel tap now.

P.s. I also noticed that after doing the conversion, that even with my fuel tap turned off, when I went to remove the tank that fuel still pissed out of the fuel tap.

Tony means a quick release dry break coupler where you can put it in place in the fuel line from the tank to the carbs, when the bike is sitting for long periods of time you open the coupler and it splits the hose but doesnt leak any fuel, I had one on my track bike and have one to fit to my HRC castrol bike
