Mikey's new to him 1980 650

[Mikey]

When replacing the fuel lines I had the tops off and the diaphragms looked good

Looks like the caps are off

have you removed the idle screws, checked all the parts are in place?

Pulled float bowls insured these orifices are clear?

removed pilots made sure THOSE orifices are clear? Rubber caps still cover the pilot wells?

I take it it's time to pull the carbs off to start digging
I'm going to push the bike to the back of the shop and start digging in

PS I've had those plastic filters fold up in use like a K-Mart tent in a wind storm.

Mikey. In the pix of the "Electric choke" it looks like your carb mount is cracked. Are they in good shape?

Here's one BS34 thread

that should keep you busy for a bit.

tent? Mountain hardware 3 man side entry.
I don't add filters, my bikes get me where I 'm going.

...Bikes get you to where your going? Uh-huh. My luck don't work like that. Filters is kinda like spurs! Guy says, how come you always wear yore spurs. Says I, kinda like rubbers, better to have em' and not need em' than need em' and not have em'. Kinda like filters, gas, oil, internet, coffee...

They have (I know there not alignment marks) but there's like casting

lines on them

It's Sunday traffic shouldn't be too bad

Yeah, and Super Bowl Sunday too. People trying to get to the beer store and back before the commercial is over. Dangerous!

Oh, Ok. I was asking because mine were shot. I also put some new ones on the Honda and they were cracked in 3 months!

View attachment 197304 I didn't connect up the vacuum line to the carb
Edit : to the petcock not the carb
There seems to be a little more fuel in the filter
When the bike is on choke it idles nicely at about 1400 if I try and slowly give it a little throttle the rpm's go down till until it dies

I think that filter is on backwards.

I didn't know which way they went but I will turn it around Thanks

I'm just now going thru the carb section in the tech area to try and get a feel for what I'm going to be getting into

 

[Mikey]

Lets move the carb jetting issues that I was asking about here where I can't loose them
I didn't think I needed those brass plugs other than keep crud out
When I look at these parts fische it's hard to tell whats what
I got to stare at it again to find the orings for the idle screws

here so I can keep track of them

Partzilla sells mix screw sets... the screw, spring, washer and O-ring. Here. At 8 bucks a set, it's a no brainer to me.... replace all of it. I even keep a spare set on hand now jus' 'cause I can.

Yeah I'm going to order 2 sets
I have a bunch of pill bottles that I use to store and identify parts for later

 

[Mikey]

4 sets coming this way and I also needed the left front foot peg so what the hell
As always Thanks !!
Mikey
I swear I could have stared at that parts diagram for hours and not figured out parts #s
I needed
I have a local Yamaha dealer under 2 miles from me and they have found parts that didn't seem available except at some lonesome dealer (like 1 available)
But if the parts seem a little spendy I'll use their parts # to search the web and keep em honest
I've given them a few bucks so they don't mind especially during retired guys shopping hours
