When i try to start my Ft with the starter its like the engine only cranks over once before the starter lets go and spinns free. So sometimes it works, and the engine do ignite and fires right up. But most of the time it doesn't. And I'm not able to keep cranking the engine by holding the start button in, because it disengages after one crank. So far I have been able to rollstart it successfully, and it runs good when i get it running.

So what do you guys think could be the problem that causes the starter engine to disengage to early?

It is the solenoid mechanism that locks the pinion in engagement with the ring gear with the starter button pressed. The spring unlocks the pinion when the starter button is released, so it would cause the starter pinion to stay engaged if it were broken or unhooked.
I don't really think the wear on the gears is related to this issue, but I do see some odd looking marks on the flywheel, below the teeth? Perhaps it is a reflection?
My bike will sometimes do the one crank thing maybe once or twice before catching hold, and the solenoid mechanism seems to be free. I have noticed that my starter button sometimes needs more than one push to activate, and I suspect this may be related.

Hello fellows, well I had my first non-startup tonight of my rebuilt engine.

Exactly the symptoms as AndreLindholm discribes.
Late and a bit nackered, so I think tomorrow I'll swap out a spare solenoid I have, if the same.. I'll bump start to get it going. Then address the starter issue.

AndreLindholm did you resolve your starter? cheers

Good news. You know how these things play on your mind... unleft... So just went out took the plug out, gas off, cranked over good, no disengagement, plug a little wet,  good spark. Put a little mozzy spray in the pot. plug in,  full choke...3rd crank ..and she hummed up.

I guess the engine was pretty tight, and it just needed a bit of wind over first.

I overhauled my starter so now it seems to be working as it should. And like you describe, when the plug i removed it doesn't disengage but with the plug in it still lets go as soon as the compression makes the engine cranks over.  is that normal? Maybe the solenoid need to be changed? I have clean and lubed it. 
But I pointed my attention to my carb. Because it seems that the times that it is really hard to start it the plug stays dry. So i tried removing the plug and crank it over until I smell som gasoline, then back with the plug and starts up on the first och second try. So i have sent my carb to Carb specialized shop that will diagnoise it and see if all is right. So far i have always been able to bumpstart it, but it needs a few revolution before it starts.

So I think I'm getting closer to solving it but I'm not quite there yet.

Donlukas:
Just took my solenoid apart.

I wasn't the first.

Missing thrust washer and spring not hooked up.

It started sometimes without these parts,, should fire right up after I find a washer and clean these parts.

Hey Donlukas,

 Welcome to the forum. I'm not able to help you with this question, but you might find some more information here: http://ascot500.com/index.php?topic=427.0  Check with forum member "johnnymot1" as I think that he just went through this.

Good luck
J.
