I had a problem like this on a Husqvarna enduro. it behaved just like this, it had a Dell'orto carb. Anyway, the problem turned out to be very very small pieces of grit in the fuel tank, small enough to pass the filter screens but big enough to get the float needle stuck. I cleaned out the tank and installed an extra fuel filter, never had a problem after that.

It was the AC regulator that was broken.

got me a 2000 txt 280 a couple of weeks ago. It needed some restoration, fan hotwired to always run, among other things. Thermostat was in place and it was working, so i hooked it up using the schematics from trialspartusa.com. I am pretty sure that when fan came on, it ran at constant speed, regardless of engine speed. Now, after having bike apart and frame stripped to do some welding( rear shock mount broke off), fan varies its speed with the engine speed. What have i done wrong reconnecting ? I did fire up the bike with a faulty regulator and headligth bulb blew out. Could that have damaged the fan rectifier? ( actually i rode it til fan came on) This faulty ac regulator was mounted on bike when i got it and fan was running fine and steady..

Hey all. Got me a trials bike again after riding solely enduros for the last eight years. I started in trials in 2000, on an ol Montesa Cota 242 '84, and quickly got me a Gasgas GT 32 '91. (That was at the age of 30+ ) Rode it for a few years, then decided to go Big bike, so I got rid of the trials bike in favour of a Honda NX650 Domainator. That was the wrong bike for me. I rode it nice and shiny for a week, then wrestled it down a narrow trail, and fell over on some rocks and roots into a deep puddle of water, plastics were flying in all directions.. Went huntin for enduro bikes instead. Finally settled for a 4stroke Gasgas, and rode it hard over a few years, and last year I got a new bike, another gasser, a 2-stroke 300. Lovely bike. Anyway, the 450 was sittin all lonely in the shed, so i decided to let it go. Now, with money in my pocket and an empty space in the shed, plans for a trials bike was born. Mind you, used bikes in the 1500 euro range are scarse in Sweden, and if they ever show up for sale, they are gone in a day or two.(At least the good ones) Anyway I found a 2000 Gasgas TXT280 not too far away from home, and it was looking reasonably good. So deal was done. I knew it had some issues, like a blown water pump seal and linkage bearings was shot, but I do my own wrenching so it should be ok. Looking forward to take part in this here community. //Thomas
