The CB1100 Community Forum

So yesterday I decided to replace my slightly leaking Cam cover gasket. After about 2 hours of cursing and struggling with all the plastic crap under the tank, I finally got it replaced. I then tried to start the bike but it only cranked, no fuel pump and no spark. I eventually traced the fault to the bank angle sensor which I had remembered dropped on the floor. After a bit of vigorous shaking it came good....must have gotten the pendulum stuck and now the bike runs fine. Note to Mr Honda....Can you make the ears on the quick connect fitting on the fuel tank a tiny bit longer so I can actually squeeze them in or move the tank outlet to a place that is accessible. I don't have large hands but trying to release the fuel line in a very small space is a real pain.

Others have commented on that as well

... or perhaps in other words: Honda Factory hands.

Nice job Tezza, my gasket weeped a slight bit of oil but after re- shimming the bike i pulled it out of the valve cover, cleaned it and re-glued it back with ados F2 making sure it had a continuous bead of glue to retain it to the valve cover.
The seal is made to seal on the head mating surface, the valve cover has no means of sealing it by itself, it relies on this glue to provide a stop for the oil to leak out and also put some sealant in the four corners of the half moon chrome cam boring covers, the result is no more oil weeping.

For some reason my cb1100 would sometimes not start as per normal but it always gets going again a bit later, this happened maybe twice but was still a surprise.

According to the simplified diagram ( which i have just checked against the factory diagram ) the bank angle sensor also prevents the bike from being cranked over if you follow the pink current path;



from what you describe could be the stop relay contacts or even the 20 A fuse contacts?
That would let you crank but no fuel/spark, all the other gear would not cause your no start as far as i can tell.

No doubt what you have done worked and congrats on the success but i thought i would assist by providing the diagram for your benefit.

And yes, the fuel "quick" disconnect is difficult, i also push the connector further on the pipe to relieve the death grip it has on the crox ring, that helps a bit.

Well done and yes, it is a real trick to get that big plastic heat shield in and out, which way did you get the valve cover out, right or left?
i believe it gets easier with practice, all the best Tezza!

you need to take it out from the right side. The clutch hard lline and the wire harness make it near impossible to get it out from the left. My daughter managed to release the fuel line at her first attempt.

Pictures or it has never happened

I damaged that stupid fuel line disconnect when I took mine apart, and had to replace it. You replaced that gasket in two hours! Wow! That probably would have taken me four hours just to replace that! My valve cover came out without too much hassle, but I actually had to ask for assistance from a friend when I was putting it back on.oh how I miss the good old days when I could completely inspect and adjust all the valves on my 1976 CB750F Honda in about an hour. The tank was held on with a rubberband and you could remove it in 30 seconds, and you didn't have to drain it first.

Hmmm... Just curious, are our bikes assembled by virgins? Or maybe just certain trim levels? That would definitely add the bikes some value.
