[XS1100 runs out of steam]

Hi group,

I am a huge XS1100 fan, and have owned, maintained and restored several 1979 XS1100s. I like the 79 model because of its reliability, styling (decals) and kick starter (for praticality rather than machismo).

My current XS11 is a 1979/80 hybrid. Two years ago I bought a running 1980 bike primarily for the engine, seat and tank, and had it fully serviced, including carb overhaul and cam chain replacement before I totally dismantled it, and have spent two years building up a fully restored machine pulling together the best parts of several bikes.

The roblem is that since I finished the rebuild, the engine runs out of steam at about 110kms. The strange thing is that the machine goes like a scolded cat up to that speed, but then feels like it has run out of gas. The local Yamaha dealership have been working on it off and on for three months, and have thrown in the towel saying that they just can't pin-point the poblem.

I have fitted new inlet manifolds, new carb diaphragms, carbs overhauled and balanced more than once, plug caps changed and timming light shows seemingly correct advancement.

It idles nicely with good throttle response, and the drop of the clutch is as exciting as ever, especially with the sidecar attached because the home-made wheels are considerably smaller than the standard 19" alloys and the altered gearing easily lights up the tyres.

But as soon as I get to the outskirts of town and my speed increases to around 110kms, the engine loses power and I am forced to pull over and wait for revs to rebuild before I can continue. The engine doesn't miss-fire or blow smoke, and has good compression across all four pots. The engine is in good condition and set up as a sidecar has gone over 170kms/hour and has been timed at 15.5 seconds quarter mile (with out second gear). There is something very simple preventing this engine performing as it should, and the local Yamaha dealership and I have run out of ideas...can any one help?

If not your gas line then probably your coil. Once the engine runs at higher rpm your coil cant supply the amount of current your engine is demanding thus make your coil very very hot. You can drive your beast w/o seats & check the coil if its getting hot. If it does, then, replace it w/ a new one.

I does any one own a XS1100. I really need to sort these pipes out. I have a petrol tap each side of the tank with 2 outletts. and 4 petrol pipes on the carbs. I have changed them all round but it still keeps pouring petrol out of the back of the carbs. I wonder if any of you guys have a xs1100 and can tell me or send me a pic which way these pipes go.

Thanks Guys

1. I suspect it's your float valve that is not working well or stuck up. Try to overhaul & synchronize the carbs.

2. If your float valve is ok then it's your petcock. We are using a diapragm type of fuel petcock. Once the engine starts, the diaphram will open & supply gas to the carb. Once you stop the engine the diaphram will also stop the supply. So no more overflowing of gas to your carb.

3. Try to check the replacement parts from Partsnmore. They have a cheap manual on/off petcock.

Hope this will helps.

1. 1 push start ok. nice accelration & evrything.

2. After driving 5mins the engine will cut off & the battery will be drained.

3. After a few more minutes, the engine will start again & that is the cycle now. Start, stop, start. whew!

4. does this have anything to do w/ my coil, rectifier etc?

Pls help! Thanks!
