    I may be wrong, but I don't don't think there is any venting through the cap. As I understand it the venting is through a line out the bottom of the tank that ends between and slightly behind the foot pegs. This also serves to direct over-fill. While I agree that vapour lock sounds like a possibility, the cap shouldn't be the source of the problem.

    Was it raining when you had the problems? I had a similar sounding issue on a trip through New England last summer. We were riding in pouring rain for most of the week. On the first day of rain I though I had run out of gas when the engine cut but after a few days of repeated issues (always in rain) we clued in to the vapour lock issue. I believe ince the rain got heavy enough there was enough water getting up into the breather line between the pegs to block the air flow long enough to starve the carbs. To test the theory I would twist the gas cap open a little when I felt the tell-tale sputter. It worked every time.

    I've read in the RAT forums that cutting the end of the breather line on a sharp angle will solve this problem, but I haven't felt like getting soaked to test the the theory yet.

    How did a very full tank of gas cause that? Not doubting, just relatively new to this and want to understand.

    I sat on a Scrambler but it was too tall, but the base Bonneville with the mag wheels fit me perfectly, but I like the exhaust look of the Scrambler...does the Arrow exhaust for the Scrambler fit on the base Bonneville, has anyone done this and how did it turn out?

    I have never actually done it but I can say that the Scrambler has a different right-side cover to clear the exhaust which is about $150 and you will have to additionally weld a mounting point under the right side of the seat to bolt it to. I don't know if there are any other modifications required or not. If you don't specifically want the mags you could probably put the shorter Bonneville shocks on the Scrambler much easier.

    Picked this up on Sunday. Haven't had any real time to play with it. Bike is in excellent condition. Look forward to getting to know it better.

    tank badges arrived, looked in the tank with a mirror and could see the studs from the inside so off the stock stick on badges came!

    It was not wet out. I filled the tank and rode two blocks home, lifted it unto the centerstand and the very full tank forced fuel out of the cap and into and out of the overflow-venting tube. By all accounts this leftover fuel in the tube could have help or been full cause of a nonventing tank. Your suggestion jogged my memory of the circumstances that lead to my demise and am now ever surer that I was under vapor lockdown.
    If the line is not straight down and out, it may create a sort of P-trap arrangement and therefore create its own failure.
    I long ago removed all extra hoses that felt superfluous and will recheck the drain-vent line out.
    Thank you, this has been much help.

    Scrambler has a exhaust hanger under passenger seat on right side also.

    ^^ Is your evap canister full of gas? I've heard about the evap can filling with gas and choking off the slight air bleed that travels thru this system to vent fuel vapors back into the intake flow. The lack of this bleed air will effect idle & throttle response.

    I've been thinking that the Scrambler would be a great bike for me. I've been poking around in this thread and most everyone posts pics of the right side of their bikes. Someone "accidentally" :D posted a left hand shot and I almost swallowed my tongue. I had never noticed the rear brake caliper sticking down for any passing rock to demolish. What was Triumph thinking?? Is there a guard available or a way to relocate it? Here in New England we have rocks everywhere. I was thinking about riding the Scram on Jeep roads that have basketball sized rocks all over the place. How do you deal with this issue? (or is it a non issue?)

    Nice shot of the rear knob! Did you go with a 140 Conti TK80?

    The solution is to purchase the UpNOver caliper bracket from Triumph Twin Power:

    All that stuff is in the city dump along with the AI as I felt it was only artificially intellegent to supercharge my exhaust gases and my bong never needed that much air injection, why should my other high.

    Hi well since it return in 2009 (or that's when I saw it) the Scrambler has been in my short list of bikes I would like to have even if they are european (because of the price of maintenance...I think). All is good except 2 things, I believe it has tube tyoe tires, a chain and most important it is the exhaust!
    [​IMG]

    So my question is, how hot is the exhaust? can you feel it? how about putting luggage? And over all does that have one, what do you like or not like about the bike?

    I want it for just going around town or across the state and crossing into the USA on day trips, nothing like Alaska or Tierra del Fuego.

    Thanks

    :huh Uh..what? Who's yelling?
    Yeah and being on reserve wouldn't make it stop running.
    I don't get this post at all.

    o I had not seen that one, only the one of the Bonneville, so I hope the question I ask is there before page 1000

    Thanks

    I think the Scrambler is cool looking, but after looking, reading, sitting on in showroom for several years, my take-away is that the Bonneville is more bike for less money, has more power, is just as usable "off-road", and is easier to put luggage on.
