GS 450L running kind of

[John Mellencamp]

Well after getting the bike over a year ago I found one of the needle jets upside down ,cleaned carbs ,fresh tires and adjusted the valves . I was surprised she started up but revved way too much and realised the intake boots wern`t tightened all the way . Still having trouble getting it too idle will try again tomorrow

Hey, I got the same bike .

You have lower handlebars. Check the throttle cable and see if it's kinked anywhere. Maybe now it's a good time to get GS450E/S throttle cables. Or you can reroute your current throttle cable. Try disconnecting the cable from the carburetors and see if that does anything.

Another thing to look at is the butterfly valves in the carburetors. They should barely be open.

I also noticed how hard it was to start the bike. Did you rebuild the carburetors yet? Did you adjust the engine's valves yet?

Do this stuff and let us know what happens. I'm thinking it's something as simple as a stuck throttle cable.

Your bike sounds very similar to what my bike sounded like a couple of weeks ago. It was very hard to start, and when it did start it would race up to 2000rpm and then die. I had a hunch it was the igniter since I had just cleaned the carbs, so all I did was run a ground straight from the battery to the igniter and it fixed all my problems; the bike starts first try and runs fine.
hopefully it's something as easy as that, keep at it, you'll find it.

Didn't have time to watch the whole clip just yet but it cranks well and even though it rev'd it sounded good!

I'd be sayin' "holy moly" too... haha

Yeah Pete it was reving up to 8k and didn`t want to push my luck so I was switching the bike off with the key Took the battery out tonight and noticed one cell was dry so filled that with some distilled water but thinking that might be my problem . Going to try tomorrow and see what happens

I like how the smileys are perfectly lined up.

Anyways, I don't think that the battery is your revving problem but it's a good find. Fix it then try again!

 

[John Mellencamp]

Yeah after the video I tightened up the boots around the carb and got it to settle down a little . Then it wouldn`t start and I know how a dying battery will give you major headaches Also in this video note even turning on the blinkers dosn`t help

I was amused by the wrist twisting between starting attempts.

Just so you know, it does absolutely NOTHING to help start the bike.

It doesn't hurt anything, either, but it does nothing to help.

Good call Steve, noticed that myself.

I used to do the same thing until I got stuck deep into these forums and realised with no vacuum it would do nothing at all...

Good call on the throttle cable all it needed was loosing at the carb end now I have to adjust the idle screw so it won`t die . It sounds like a monster when I start it up and not like a 450 I noticed on one of the boots at the airbox side was leaking smoke guess I should have replaced them The screw holding the boot is all the way tight but seems like it needs a different clamp on there to get it tighter .

I knew it! That's what happened to me when I put lower handlebars. Brand new carb intake boots are good. Get the clamps too. They are a bit expensive but I'd say it's worth it.

My fuel screw is 2 turns out do you think going in a little or out would help and which way would help with helping it out to idle down low .

[John Mellencamp]

Well I decided to go 3 turns out too richen up the fuel . I probably should try a quater of a turn at the time but I`m going all out going to try and start her tomorrow

 

[Guest]

I used what I think is called the "highest RPM method" to adjust mine years ago and I ended up with one 2 turns out and the other 2 1/4 turns out...

 

[John Mellencamp]

Oh I feel stupid now got my new carb boots today to go between the airbox and carb . Well after I tore it down to put the new ones in I noticed the old ones were pushed into the airbox and not even on the carb . So I`ve put the new ones in properly although was very hard to push the airbox back into the carb what a workout Will try in the morning and see what happens

 

[Guest]

Ooops! I hate it when my bike makes me look like a fool... done stuff like that too, very frustrating, but at least now you got good new rubbery boots to give a nice seal to the intake

Hmmm something doesn't seem right there... lots of smoke, is it blue?

Seems maybe it's rich? Not sure, but it definitely isn't idling smoothly.

It does sound mechanically good, just not firing right, whether it's fuelling or ignition though I'm not sure...

 

[John Mellencamp]

I`m going to try new spark plugs the ones in there might be fouled and incorrectly adjusted .

i would also sync them you will be surprised how much better it will run with nice even vacuum
