Honda VT250 problems, help (Ch-ch)

[Shadows]

Have look at your air box, make sure its selaed properly and there are no holes that a breather pipe from the crankcase should be plugged into

i have the 84 VT250, had a similar problem after taking off the fuel tank, turned out i had put the vaccum hose onto the wrong bit of the fuel tap, there were two fitting it could be pushed onto, and the most predominant one was wrong, so did the hose pop off the engine? carbs? fuel tap? where exactly as i can look at my own for you and hopefully tell you what its there for

ok new update, followed the hose that had come off and it leads back to the fuel tap, its the only small one about 3mm wide, and came off opposite side of engine,

so ive come home , tried to start , its ticking over and will occasionally ignite and start but only for a second with full throttle on, the choke is not working, engine will not hold revs!!!

unfortuntly i have no idea what the carbs look like??
on the fuel tap there is two hoses for the fuel, one for reserve and one for on , then there is the one hose going off the tap to the engine??

im not sure if this is the problem as it is now reattached, this was my intial problem, but now i cant run engine!!

2 hoses or 3? 1 or 2 larger bore are fuel. 1 smaller bore is vacuum.

You have a V-twin engine that runs 1 carb per cylinder. The crbs are both in the valley between the barrels. The small hose will go from the inlet manifold (engine side of a carb) to the fuel tap. When the engine is running, the vacuum created goes up that small hose to the tap under the tank and opens a valve in it, allowing fuel to flow down the 2? bigger hoses to the carbs. If there is only 1 large hose, it will go to one carb and there will be another hose bridging to the other carb.
The fuel tap switch will have 3 positions....On, Reserve and Prime. If that vacumm hose failed (which it did) the engine used up the fuel in the carbs and of course, stopped. Replacing the hose is not good enough, since there is no fuel in the carbs. Put the tap switch to Prime for a few minutes. Turn back to on and try starting. Should go now....

i just checked out the manaul i downloaded and the hose that came of is called the automatic fuel valve line, i have it reconnected and yes ive had it on prime , ive had the engine running since, eg i just managed to start it but had to have it at full throttle and was still only on 1000rpm for about 2 mins, then it died again, so there must be fuel in there if running for two mins, ???
engine still will not start and hold revs, just keeps dying

OK well that's the problem, the fuel tap vacuum hose came off. Ridiculous fault-prone things.

To rule it out, set your fuel tap to the `Prime' position. This will mean fuel will pour into the carbs regardless of the vacuum hose working or not. When you've had the fuel tap off/carbs empty then you need to switch it to prime anyway just to, well, prime the fuelling system as there'll be nowt in there.

Leave it on prime for 30 seconds or so first before trying to start it.

When you got the bike, it was running fine. Then it 'died' and that vacuum hose had come off at the engine end. Right?
That hose off is the cause of your problem and it is fuel related. Yes, some is getting through but not enough. I wouldn't mind betting that vacuum hose is blocked in some way.

yeap the guy rode it 20 mins to be, then i rode it 2o mins, then it died

i want to mention the hose seemed to have popped off, an then id reattach, then start again, and itd pop off, ive cable tied it on for now but still nothing happening, like i said i cant get any revs off engine, but sometimes it will start on full throttle for like 2 mins but then dies again

if it is a blockage can i just take off no problems and check???

also you sure it wont be a carb problem??

[vt250]

unless you reckon the valve in the fuel tap is bung???

or the filter or something

[MSTRS:Me]

It popped off, over and over? Yes? The hose is fucked and not sealing properly on the short pipe it pushes on to. Get a new hose. And then tell us how the engine runs etc.

[vt250]

the manual states for fuel problems
HARD STARTING OR STALLING AFTER STARTING
1.IMPOPER CHOKE OPERATION
2.IGNITIONN MALFUNCTION
3.CARBURETOR FAULTY
4.CONTAMINATED FUEL
5.INTAKE AIR LEAK
6.IDLE SPEED INCORRECT
7.INCORRECT CARBURETOR SYNCHRONIZATION

so you reckon even though the hose is staying on now its still the problem, um not to sure were to get hose that small from, and repco etc dont have clips that can hold it on small enough
weres the best place to go.

Can i take the end off the fuel tap without any problems

[MSTRS:Me]

What I am saying is that the problem started with that vacuum hose coming off. Or at least, the hose is associated with the engine not running. And until you know for sure that it is (or isn't) the v. hose at fault, don't fuck with anything else. OK??
