Oh no you mean I have to disconnect that thing again :D

I found it nearly impossible to connect the fuel line to the carburetor when they were on the bike. Please dont make me disconnect that again haha. Maybe I can disconnect it from the tank end :p

yeah, its a pain. use some needlenose pliars to get it in, and raise the rear of the gas tank up and put something under it to hold it up out of your way some. been there done that too about a dozen million times it seems.

Wow, no wonder you're reluctant to pull that. Put that line on the carbs while they're off the bike and you can get access. Once installed, just connect & disconnect the tank end. You'd need the patience of Job to get that line off the carbs while they're installed!

Haha yep, as soon as I put them on I realized what I had done. Ended up having to slide them back out to connect it the first time.
 
Make sure fuel reaches carbs; doublecheck plug wires are on correctly (left coil fires 1 and 4- right fires 2 and 3). Make sure choke is working at carb end (choke plunger bar moves 1/2 inch out). Remember no throttle input during "choking". If no go after 30 seconds of cranking, pull spark plug to determine if fuel is there.
 
Next time you have the carbs out, put a zip tie on the bottom. Nothing worse than pulling the line off the carb when you are trying to remove the line from the petcock.

Hey, I offered several times, never got the official "Okie dokie".

I was going to stop by and help for a bit on my way home from upstate NY, but Zach said he was doing his MSF class that day. That will trump a visit from me ANY day.

I couldn't sleep Friday night, got up early Saturday morning and started driving home. Went past his house about 1330 and left a couple of mixture screws for him.

You SHOULD disconnect from the tank end, for the fuel AND the vacuum.

If you are using correctly-sized OEM lines, it's easy, and you don't need any clamps to hold the tubes in place.

Unless a previous owner has swapped the coil locations and the left one fires 2 and 3.

Yeah, he swapped all the wiring, too, so everything worked OK, just that the coils were in opposite positions.

I know this is random but are your spark plugs dry? Throw some fuel into each cylinder and put the plugs back in then start her up!

For the battery, just use jumper cables and connect you battery to your vehicles battery. Just don't start your vehicle... Only the connection is needed.
 
Wow lots of good recommendations. I'm completely exhausted from MSF weekend and a slight mishap with the car this morning that almost made me late!!! So I didn't really get to the bike today. I picked up a battery tender junior and its charging now; I'll check all this stuff tomorrow probably.

Just for kicks I gave it one more attempt. Battery had enough juice to crank the engine just a bit, and it gave an encouraging rumble from the muffler just as the battery went dead again. I think it may have started if the battery was charged this time. We'll see what happens tomorrow. I'll be sure to check how the plugs are connected too - I haven't changed the order of them but maybe they're not right.

In other news, I now have my endorsement from my MSF course and will be able to get the M on my license later this week. Woohoo!

I'll post back here tomorrow after I have time to fiddle around with a fresh battery.
 
Well, after charging overnight the bike fired right up this morning. I'm wondering now if the battery is in poor condition; maybe it was discharged after a week of sitting to the point where it could not deliver enough juice to fire up the engine? Definitely something I will keep an eye on, unless anyone has another theory.

However, even with the choke off the bike was immediately idling up to 4k, 5k RPM. It seemed to maybe be climbing higher too. I shut it off before that happened (also didn't want to wake the neighbors at 7AM :eek:).

So were do I start? Turn the mixture screws in a half turn and then turn the idle adjustment screw out if it still idles high?
 
Don't go playing with your mixture screws until you get a decen idle at about 1100. Turn the idle SPEED knob about half a turn counter-clockwise to bring the speed down, try again.

You don't play with the mixture screws until the bike is warmed up and off of "choke".

Ah, OK thanks Steve. I'll fiddle with it tonight, stuck at work now :mad:

Will report back when I get a chance to mess around. I did leave the valves slightly open after doing the bench sync, and I remember when I started they were pretty much completely closed (the PO had them that way). So maybe that's all it is.
 
Wow, wow, WOW this thing is running so much better now :D:D:D

Not only is it starting up just fine but after adjusting the idle speed, a lot of the symptoms from before have disappeared! Seemed to be a pretty consistent idle after riding around the neighborhood for about 20 minutes. It didn't dip or try to stall on me once.

Once hot it was idling around 1600 rpm. I know you're supposed to adjust it when it's hot... so I'll have to do that but I didn't have anything to reach in there and turn it. And I didn't want to burn my hand trying to reach in there :rolleyes:

Holy cow am I happy though, it runs pretty smooth, can't wait to get the fine tuning down.

The only remaining symptom is still a noticeable gasoline smell from the exhaust. It doesn't seem as bad as before though, maybe I'm just paranoid. One... step... at... a... time.

Thanks all for the help and recommendations. You all rock.
Here's a video of it running after first starting it and getting the idle speed set

first turn the idle down to 1200 and let it warm up and adjust it when warm to 1000rpms then go on and follow (koolaid-kids) wright up on setting the a/f screws. i would start them at 2 turns out to start off then follow his write up enjoy
