VAPOR LOCK: THE FINAL SOLUTION!

Hi all,
after asking, searching Everywhere, I've found the FINAL SOLUTION for the VAPOR LOCK ISSUE affecting many HUSBY lovers....
you need to check the gap of the pick-up of the start (accensione in Italian)
if this pick-up gap is not well regulated the engine stops and has incredible difficulties in firing up.

The solution has been suggested and discovered by a mechanic that follows a rallye team here in Italy and proven 100% successful.!!!

Hi. Thanks for the advice. Could you try to explain what you mean again? I don't understand what gap you're referring to. Maybe post a picture from the manual if that makes it easier.

Thanks for your time. Hopefully you've discovered something.

Re: VAPOR LOCK: THE FINAL SOLUTION!

I am not an expert at all in the technical field...
they explained me that in the start there's a Pick-up that has to have a certain gap...when the measure of this gap is not as the dealer's manual tells the bike when's hot sometimes doesn't fire up untill it cools down.

Re: VAPOR LOCK: THE FINAL SOLUTION!

Are you referring to the start motor, or starter motor?

Re: VAPOR LOCK: THE FINAL SOLUTION!

Thanks for the advice. Would it be easier to describe the situation in Italian Pongo? Feel free and I'll have my co-worker translate for the board.

Cheers.

Re: VAPOR LOCK: THE FINAL SOLUTION!

Most probably the pulser coil to flywheel air gap.

probably that's the one...
the distance (gap) between the pick-up and the flywheel has to be the one of the "dealer manual" ..if the gap is not the correct one...and after many hours of use that may well be the case....especially when the bike is hot, it doesn't fire up.
I've completely solved the problem...without wrapping the pipe or the tank etc etc

Bear in mind that the "user manual" doesn't mention this...so it has to be taken to the dealer...and he should know what the gap should be!
hope that helped...

Re: VAPOR LOCK: THE FINAL SOLUTION!

I hope you are right, but how does that explain the common situation where a rider restarts the bike with indication of a problem yet, the bike runs 10 seconds, sputters and then dies. Then, it will not restart unless you wait for it to cool down a while.

The previous theory is that there is enough residual fuel pressure that the bike can start without the fuel pump, but the fuel pressure goes away after a very short time when the engine fires.

Re: VAPOR LOCK: THE FINAL SOLUTION!

What he is describing may be yet another problem with some bikes. I know in my case that when mine got real hot and I shut it off it would start back up just fine but only run for a few seconds and then die like it ran out of gas. Then it wouldn't start again until it cooled down. My symptoms don't sound like the "gap" issue. I recently changed my pump to the ca-cycleworks version so I will see if that solved my problem.

Re: VAPOR LOCK: THE FINAL SOLUTION!

It may well be that ounce the gap is not as it should be...the bike may well work not as it should do...therefore one of the symptoms may well work for few seconds and then off until it cools down....
as i said i am not a technician, but i really trust my mechanic whic is considered a real Husby Guru
