XT600z 1VJ 1988 possible fuel pump
Guys,
how do I check the fuel pump.
If my bike is not used for a 2 weeks it is slow to start.
It turns over no problem but no fuel.
When it starts it only runs for seconds and stops.
This is the happens about 5 times and then it runs fine.
Also hard to start if it runs out of gas and I switch to reserve.

I am guessing fuel pump?????????????????????

My '88 1VJ doesn't have a fuel pump....:confused1:
But it sounds like your carb could use some servicing....wouldn't hurt to have a good look @ the fuel tap as well.

Hi,

Are you sure your bike is a 1VJ? My 1988 Tenere is a 3AJ (Twin headlight fairing)

Gravity will supply most of the fuel from the tank so you could bypass the fuel pump and see it things improve. But remember you will no longer be able to use reserve and your range before reaching reserve will be a little reduced.

It could be fuel going state in the carb’, for some reason it goes off here much quicker than in the petrol tank. If the bike is not going to be used again for a week or more, try turning the petrol taps off just before you reach home so that the last couple of minutes ride empties the float chamber. Then when you next come to start it, open the petrol taps and fresher petrol is available to start the bike. If you do not turn the petrol taps off at the end of a ride, doing so may also help


Using an iridium tipped plug may also help. They are three times the price of a regular plug but they do last 3 times as long, and you only need one.

Hope you sort it,

Mark

I would guess its stale fuel in the float bowl drain the carb by undoing the drain screw let a bit of fuel out tighten screw and engine should start.
If my TTR is not run for a few days it is very hard to start, drain carb and it will start easy.

My 88 1VJ doesn't have a fuel pump
Its number plate is 1992 but wheels are stamped 1997, so I am thinking its 88. Imported from Italy it managed to gain a few years!!!!!
Its the old single headlead model with 25litre tank and drum brake on the rear wheel. every part I take off has 1Vj stamped on it.

Hi Its pretty rare for the fuel pump to go wrong on the early XTs, but if you want to check it pull the pipe off the carb, thats the one from the pump, make sure the fuel tap is on, give it a quick suck if you get a mouth full of petrol that stops when you stop sucking on it then its working ok. Yor best bet is to start by giving the carb a bit of TLC. You may all so want to check the fuel tap filter in the tank as this maybe blocked due to a build up of crap in your fuel tank. Hope this helps Skip
