Almost there (timing?)

[Hartless]

So, I finally have began investigating my problem further and have came to a conclusion that there is a stuck valve. I am going to swap in my spare head and see what happens!

[QBS]

A stuck valve in a V probably indicates valve piston contact.  Any contact indicating marks on the top of the piston?

Maybe...but not always. It may well be a gummed up, sticking valve that needs removing/cleaning or replaced...or it could be a :-\ Ah well, we shall soon know when Hartless removes his head ....... from the Vision that is :o ;D :D :D :D :D :D... ;)

I think this is more likely the case then it hitting the piston. This happened directly after I put the motor back together and the symptoms happened immediately. (spitting gas out of the carb) I did check the cam timing and it was off.... But it turned
By hand freely before I ever ran the engine. I originally had a different head on and it would not turn all the way and I figure now it is because the cam timing was off. So HOPEFULLY I should be able to swap out the original head and be riding soon!.... But I have made MANY similar statements In the past and.... Well here I am talking about it Again!

I've seen bent valves that were not stuck. Stuck valves  are usually the result of carbon or varnish in the valve guide.

Have subscribed.  You had me at hello.

This is like one of those vision version of the mentalist.

I got similar symptoms to you and thought it might be a valve as well. Put some upper cylinder lubricant in the fuel. It turned out to be a combination of minor things. In order of importance, these were:
1. Failing spark plug. Replaced with non resistor plugs
2. Failing resistor spark plug caps. Replaced with new NGK's.
3. Once it was running again, Carbs way out of balance. - Rebalanced.
4. Sticking float valve causing overflowing to front cylinder.

Now she starts really easy and pulls like a train. Still needs tweaking but at least rideable.

Good luck

That's so true with many Visions - it's often a host of problems with overlapping symptoms. Working through them all is a process and can take some time to get right.  :) ;)

That's always nice to read - another Vision well on it's way!  :D

That is originally what I suspected and I changed all that, but to no effect... :(
