Hi All,
Here is what we got
1987 Savage 650 11,000 miles. Has not run in at least two years. I bought it about a month ago to upgrade from my first bike (99 250 Marauder loved that thing!) I only upgraded because I travel about 100 miles a day for work and the 250 was just too small to take on the highway.
The Savage turned over so I picked it up cheap! real cheap. I brought it home and started working on it. The carb was pretty gummed up, cleaned that the slide looks a little scored so Im planning on getting a complete rebuild for that. Gas tank was seriously hosed, cleaned most of the rust out of it and changed the pet out. She has some wiring issues, chaffed wires going up to the speedo, and the yellow wires that go from the regulator? were cut, replaced by somone that had no clue and had also apparently burned and caught fire, I cleaned that up and heat shrinked those after soldering back together. Already had to replace that stupid oil plug under the head cover (briliant idea Suzuki engineers)
Now for the problem, Im guessing that its just from the crappy diaphram but I thought I would run it by you all.
When I try to start her, the head unloader only moves once in a while (every fifth or sixth attemt to start) turns over fine, she will start and run on ether but when trying to use just gas she doesnt want to run, almost like there is a dead spot on the lower half of the throttle, and she will not start without ether. She also doesnt run for long once I get her to run, as long as I keep giving her a shot of ether she would keep running but as soon as the ether is gone she dies?


Now Im not really that good with carbs (last time I had to deal with one that was difficult was an old carter off an mg and that was 10 years ago)
I am pretty mechanically inclined so I would really rather do all the work myself

Any one with an idea I would love to hear it.

As always thanks for the help!

Sorry, Decompression solenoid/ head unloader (thats my diesel side coming out) same difference in my world but I did take it out an clean it really well and then lubed it a bit to make it move freely. (should it unload every time I try to start the bike?)
as far as the fuel tank, im currently not even using that, I have an "IV" old mini bike plastic tank that I can hang on the handlebars while I work on her, I find the tank was getting in the way. I am planning on running an inline filter on it just in case. I think the tank will be ok shes currently sitting on my air compressor with some nuts and bolts sort of shakin the heck out of it, I hope it works.
The slide is scored but it moves fine. so I guess it should run? Im at whits end on this one.
It should be simple.... I have air, spark for sure, I assume that fuel is not getting out of the bowl maybe??? I guess I will do a complete rebuild on the carb and see whats up.
Thanks! so much Serowbot

Make sure to cover the port for the petcock vacuum line on your carb. If you don't seal it off, you're looking at a monstrous vacuum leak. The little red rubber plug off a bike battery is just the right size...

For a vacuum slide CV, the BS40 is a tolerable carburetor. It can't hold a candle to a nice cable operated slide Mikuni, but it's decent.

Hmm... only one vacuum line... right-side of carb,(usually covered with a spring)...
Two other lines are vent tubes for the floatbowl... they should be open to atmosphere... (run up like this)(jets can't draw against vacuum if they're blocked)...

The vacuum tap in this shot has the rubber nipple cover...(top arrow)...
The line to the pet,.. is the other arrow, with a golf tee blocking it...( it normally comes off that tap... (as you can see, it draws vacuum from the intake manifold pressure)...

Unfortunately I did not get to work on her much. My hubby works third shift friday through monday so I didnt want to wake him up so Im hoping to get back to her tomorrow after work. I did get some things done. Painted the motor, changed out the side covers. tried to fix some of the wiring issues that Alvin and the chipmunks created. and I got frustraited while trying to put my old bags on her. Has anyone put bags on theirs without the chrome side pieces? Im concerned that it might put the bags too close to the tire and or belt...
