Fuel tap - advice needed

[chappardababbar]

Hello people,

I'm trying to get my new NC30 sorted. When I bought the bike it was running with all the symptoms described by forums members that would indicate fuel starvation.

It turns out the vacuum pipe was not connected to the fuel tap. Silly I know but considering I have ZERO mechanical knowledge I can't tell you how happy I am for figuring it out.....thanks to the photos and posts on here.

Okay, so the bike was instantly transformed with the throttle now super-responsive and errr.... zippy.

That lasted about 40 minutes. As I rode around the exhaust note changed and the now familiar droney background exhaust note just started to creep back with a noticeably drop in responsiveness and power - especially from standstill. Fuel starvation.

So after reading a bunch of posts the next thing I'm going to do is clean the filter and the fuel tap. I've looked but I can't find a step by step guide for either - can someone kindly point me in the right direction?

Here's what I was planning to do:
1. remove fairing and tank.
2. remove fuel tap over a container
3. drain fuel into container
4. take fuel tap apart - I'm hoping there are some screws in obvious places?
5. scrub it after spraying bits with carb cleaner?
6. Do I need some kind of pipe brush to clean it?

I have no idea what to do with the fuel filter or even what it looks like.

Any advice will be much appreciated.

Hi,
I think it may be worth getting some new vacume tube and try that before you take teh tap apart. the vacume tubes are known to collaps when warm if they have been on the bike for a while. If the bike has been stood for a while? the carbs may be bunged up with crap fuel so may need a bit of a clean.
Rick Oliver on here does the vacume tube and all sorts of other very nice bits for these bikes

Yep, what they said.

The vacuum hose is only £3.

The vacuum hose goes from the fuel tap to a splitter - this bit is about 7 inches long.

From the splitter there are two hoses one goes ummmmm to the right and down, then turns back on itself and goes into an inaccessible part of the bike.

The other part goes straight down.

Do I need to replace all three sections of pipe?

Thanks for the advice - will contact Rick Oliver today

That's the air vent. The vacuum hose goes onto the smaller spigot then goes underneath the fuel tank and fits onto a brass-coloured spigot on the right-hand rear cylinder.
