1983 GS450E build. My first bike.

Cool, glad to see you're having some success!

The '83 carbs are definitely a different beast to the '82 carbs... but I haven't seen any up close to see for myself.

Depending what happens down the track, a nice upgrade might be those from an early 2000's GS500... apparently they are quite a lot lighter than the 450 ones...

Big Rich has got some on his 450 if you've seen his thread.

Now that I've had my dyno run and leaned things out a bit I'm just fiddling here and there trying to get a nice idle and get the mixture screws happy.

Looks like my new pilot is different. Both are mikuni 45's..
Hmm.

[pete]

Which one is from your carbs? The one on the right looks like either the VM22/210 which suits the 80 - 82 carbs or the BS30/96 which I have no idea about.

The one on the left looks like a N151.067.

I'm getting this info from here:

http://www.mikunioz.com/pilot_jets.htm

All three types have a 45 in their size range, although stock on the 80 - 82 450's is a 17.5 in the VM22/210 style... although the stock one doesn't have bleed holes just to make it more confusing...

[83_450E]

Apparently the metering areas of bleed vs non-bleed are different and they are not interchangeable.
140 main, needle at clip #3 from bottom up, bleed pilot (wrong) 45 set 3.5 turns out (idles like a lawnmower)
My ignorance is frustrating. One day this bike will be set up and running proper...just you wait

[pete]

Interesting, where'd you find that info?

And yes, you will get it right... eventually

[83_450E]

Pete, it was just found on some yamaha XS forum after searching the usage differences between bleed and non-bleed type pilots. There isn't a whole lot of info on why or what the changes are but it is clear they are not compatible.

A brief update, I've gone through my first thousand miles. I've been commuting to work on it and with only one break down in a thousand miles. I figure that's pretty good considering I've done no shake down, just hop on and went.
The business end of the clutch cable, where it meets under the sprocket cover failed. I'm not sure what it is called but it is the business end of the clutch cable. Under the front sprocket cover the piece the clutch cable attaches to failed. Where the linkage comes off it's rotating pin, it splits into two halves to come around the clutch cable ball. The first bend of the split gave way and bent off leaving me without clutch control at rush hour traffic in the suburbs.
I got around the few miles home just fine...just didn't stop!
A couple of tack welds on it has held together just fine.

My carbs are now at #50 pilot, #145 main, needle clip 2nd from highest needle position (not sure what the standard verbiage is for explaining needle position.) I'll put it this way, one more clip richer and I'm maxed out.
Free revving the engine has come alive. The rpm's rise and fall directly with the throttle. It does not feel like a CV carb bike on the stand.
Road tests prove happy. It's about 90*F here at the moment and it's doing just fine.
Maybe I'll get on a dyno for some AFR readings.

Good stuff, sounds much improved! I know what you mean about the clutch part, bugger! I have a feeling you may still be able to get them new but may be wrong...

[83_450E]

The oversprung clutch springs likely broke that linkage...I'm headed to a moto salvage yard saturday so a couple of those pieces and my welder should make one ugly overkill.
Crashed last night, 15-20 miles an hour after some bending I'm able to ride again. Pictures of what comes of the front end after the weekend!

[pete]

Crashing's no good! I'm assuming you're ok?

[83_450E]

Brief update: I'm not dead yet

Pilots down to 47.5 1.5 turns out, mains at 160 and bogging at wide open. Finally. I found too rich! I'll be going to 155 soon and that should be the ticket.
I'll put up some pictures soon... I went to black clubman bars, black levers and black headlight brackets to being the headlight bucket up towards the gauges.
My clutch cable broke at about 2k miles. The over spring springs are coming out when my new clutch cable comes in. I've decided they are too tight for the factory parts to handle. I'll try half over sprung and half old stock springs. Hopefully that reaches a happy medium.

[pete]

Good stuff! Too rich is nice... now you know where you're going

Bugger on the clutch cable... I still have all stock springs in mine and so far so good.

Any pic's of the new setup?

Looking good!

That 450 looks pretty sweet to me. Do the bars hit the tank? Hope not. That looks like Oregon to me. The Madrone and the car plate make me think so. I forget if you mentioned it earlier.
