Title: Choke open 2 days, problems starting... flooded?
Post by blackhalo on 02/16/13 at 09:54:15

Hey guys, I recently transported the bike (on trailer) to a different state...
my buddy thought it would be funny to leave the choke fuel enrichment circuit ON (enriching) for my trip, I noticed shortly after taking it off the trailer.

Ever since, the bike starts hard...
at first I had to full throttle (no choke enrichment) to get a turnover, took 10+ sparks to finally kick...
but once it started it would restart a bit easier, but not back to normal.

So I've been doing it this way for a few days now, but this morning was really cold (about 30 degrees) and it wouldn't start with a full throttle...
so I tried NO throttle (and no choke enrichment)... that worked, almost instantly... but it was a really weak idle at first, sounded poor, had to nurse it closely.

Anyway, I'm not exactly sure what to fix here... are the spark plugs fouled?
Would the gas in this new city (Austin, TX) make any difference?

I'm in a hotel atm, so tearing the bike apart in the parking lot isn't the best situation...
it's do-able, but I'd like to have a plan of attack... any suggestions?

if it were a choke, it'd be no problem, as it would've closed the intake an prevented garbage from flying in there.

it is a fuel enrichment circuit.  perhaps the circuit is full of fuel?

but I'd check your petcock.  inspect the vac line for fuel... do 'bots petcock test.

Your post is a little confusing, you left your choke off for 2 days,
that's not a problem. You moved from what state, moving a bike from Colorado to Texas would cause it to run rich. If you moved from
Ca. it would be no problem.
When you start your bike with the choke pulled out, you should not open the throttle until it runs for a bit. Then go to 1/2 choke for a while.
Do the petcock test and maybe try some new gas....

Thanks guys, definitely some things to consider...
I'll take a look at the petcock test with fresh eyes tmrw.

It hadn't occurred to me, I just came up from sea level (approx 13 feet @ Florida)... to Austin (approx 423+ feet)...
not sure if that pressure difference is as dramatic as coming down from the mountains, but it's still a pretty big gap.

Oddly enough, my cars "check engine" light came on shortly after I arrived as well (that's a first with this vehicle)... sigh... rains/pours.
I love working out this kind of stuff, but the timing really sucks on these two... supposed to be house hunting!

Thx for the suggestions!

Humidity may be more of an issue than elavation? :-/

For the record....

Actually, a bike that is properly jetted for high altitude will run lean at lower elevations.....

Yep, you're right about a high-altitude bike running lean at a lower
elevation, my mistake.....

It ain't the humidity...  There was lots on FL, and not much in Austin.  It could be the springs on the enrichment circuit are stuck on "enrich" a bit.  As well as petcock...  Also, it could be fuel.  If the petcock passes, I would start with a fresh tank, and clean the carb.
