While you are on the subject of vapor lock, would someone please describe it fully. I don't think that I have ever experienced it and I would like to know what to expect and understand why it happens.
Thanks,

Vapor Lock
What do you guys do for vapor lock? Do we have room under the tank for one of those plates for the carb? I got stuck in trafic for about 1,5 hours and I vapor locked 
By the way my fuel lines are fine, it the carb that is getting hot.

If you install a 1/2" plate for the NOS you need to cut away or bend in the frame in so the linkage will clear, so if you install a plate you will need to do the same thing. I have had the same thing happen but not to the point the bike would not run, not very good, but could at least get out of the way. Mine would only last for a short while.
What causes vapor lock is when the gas boils in the line, after the fuel pump, and turns into vapor. Sounds like it is in Lamont's Carb but normally it is in the lines. In most cases the problems is caused by having the lines to close to hot engine parts like the heads, manifold and anything else that is hot.

You may be right but if I have just a little bit of ram air I never have a problem so I'm thinking maybe passing some air through there would help. I guess there's only one way to find out.Boss Man said:
Remember Daytona and I said I thought my bike was doing the same thing - After running for awhile and the engine was HOT each time I would try and "hammer it" it would cough real bad. Well I moved my fuel lines when I got home and got them away from the manifold ... so far no more "cough" but the ambient temps are not as high as FL either Your problem is a little more difficult being the lock is occuring at the carb
I think if you have a 1/4" space to work with then I would add a 1/4" spacer and get the carb a little higher ... hopefully the extra space will do the trick.
I wonder why they are all different? Mine I understand because the lines were laying on the manifold in spots (I will change all the fuel lines out next chance). I am assuming the carbs are all in the same position .... model year would be dependent as to airflow under the tank but space above manifold would all be the same. Wonder why some have problems and other not :?

Hi Don!
How ya doin? Looks like the riding season is finally here. Had some nice warm days here for a change. Even got the Boss out a few times. I think I'll be needing that new rear tire sooner than I thought! Ha Ha!
As for your question about why some do and some don't.......Who knows? But it sure keeps things interesting doesn't it!!
Hope you are well. Are you planning on going to Stamfords open house in July? ..........Don B

Everything is going great, been riding myself. My miles have been divided between the Boss and the Capo. Capo gets the "not so great" days to ride - windshield helps a great deal in rain and cold and the Boss gets the perfect days - as it should! The Valk ... well it gets a cold/dark corner of the garage still attached to a battery tender. I guess I will have to move all the bikes out so I can get it out to run the Stabil out fo the tank! I most definantly want to go to the Stamford open house! Keep me posted on dates/times, probably spend the weekend down there. I am sure I will be down before July - I'll be needing new rubber too before then

I was watching the other thread from Hoss about his fuel pump. I was getting the idea the stock pump is not the best choice. I will probably swap to a Carter like you, Wag and others are running. I hate the feeling of wacking the throttle and "cough. cough, sputter, cough ... GO"
The swap is easy enough and if that is all it takes - GREAT Don
