Question about 1998 Triumph Trident 750

1 Answer

Fuel problems I've just started having fuel problems on my 96 Trident 750. It's used daily and just started cutting out, but I can carry on running as long as i don't rev too hard or exceed 60mph. I took the tank off last night and fuel pissed out when I disconnected the hoses so I knew something was wrong. I took off the vacuum tap and found the valve was in the vacuum position. When I took it apart I found the casting was blocked so it was retaining the vacuum. I cleaned it out finding a small thin piece of rubber was blocking the hole and assumed I'd fixed it. This morning riding to work the symptoms are exactly the same. I opened the cap when I arrived at work wondering if there was a vacuum in the tank but there didn't appear to be. Any ideas?

There are two fuel pipes from the petrol tap to junctions between the carbs. Inside those plastic junction pieces, where the fuel pipe attaches are small conical mesh filters, 'witches hats' as described by the mechanic at my local dealers, it is likely that they are clogged up. Unfortunately you will need to take the carbs off the engine to get to them. Probably worth getting some new petrol pipes as well, mine had perished and become brittle after a few years and split when I pulled them apart.

Running problems with kawasaki zxr750 1993, used the bike yesterday and ran well for 8 x 20 minute trackday sessions, the bike then lost all power and cut out, it could be started but would then...

Did you put fuel in it??

After a day at the track and running at full throttle for a good majority of the day the fuel consuption of your bike goes through the roof.

When doing track days i always fuel up twice - once in the morning then again at lunch time to get me through the day.

A tank of fuel that would normally last you about 300km's will disapear in about 100-150km at the track.

Check the fuel mate, at least try it on res and see if it starts.

If it runs on res your problem is solved.

My 1994 zxr750 has got a problem with fuel tap when in the run position after a few miles it feels like it is runing out of fuel but put it to reserve and it runs fine but the fuel tank is full? help

94 zx7s have separate hoses that sit at the very back end of the tank. They take a nice twisty course to get to the tank. Could be that the main line is kinked and the reserve is not.

Or you may need to rebuild the petcock. I've got 3 ZX7s, 93, 94, and a 01. None of them had petcock issues but I've had fuel line routing issues before. So I'd check the lines first before servicing the petcock.

Yzf 750 r 1995 starts but when warm wont idle i have turn the tickover up to 2500rmp but then it jumps up and down between 1000rpm and 2500rmp but if i let it cut out it wont sart 4 10mins any ideas people...

have you checked connections on the fuel pump,pre ignition test noise is an indication it is connected as it self tests for fuel pump and exup before start.
If pump is disconnected she will run like a pig then cut out.
Another fault could be she needs new plugs /caps,running lumpy and missing is an indication of this as is mis balanced carbs.
Good luck hope this helps.

Triumph trident 750 '98' starting problem

Classic storage problem is moisture entering, coalescing, condensing in petrol and in electrical circuits what you' v done is right but try WD40 on low & high tension side of ignition and a dose of easy start, once running give a good run and store with cling film over open ports with a acumen type charger left on.
