750 Maxim build. (Gonna try to be different)

So I thought I'd start a thread about my cheap 82' Maxim 750.
I bought the bike a few weeks back for $340...
I've fixed a few minor wiring issues, and cleaned a lot of things.
I think I have it running pretty good considering it hasn't run in over a decade!
It needs a few more new parts, and some shim swapping. But I think I might have got a decent deal.
I'm only into the whole bike for $400 at this point.
I have a bunch of parts coming for it. I'm not sure where I'm heading with it in the looks department. But it's gonna get lowered, and a face-lift. (Lots of shiny parts.. lol)
I hate to say Bobber, cause it seems lazy. Let's call it a fancy street scrambler, and run with that!

 

It's looks too nice to chop it up . Looks like someone has looked after it for the most part.

 

It's been layed down.
It's not bad though, the tank is a bit beat up, and it's missing the front signal lights. The bars are bent, and the exhaust is scuffed up.
To me it's a perfect candidate for a build?

 

Ok pics didn't show damage

 

Carbs need synched.
Engine sounds really good otherwise (except for the too-quiet valvetrain, but you already mentiond shims).

 

I know the carbs are synced by eye.. lol
I need to borrow the tool to do them, but I'm gonna tear the whole bike down this winter anyway. I'll do the carbs in the spring..
What's the easiest way to pull the motor by yourself. Lay the bike on its side??

 

I need the tool to hold the lifter while you pull the shim. Or I need to make one?

 

Use the zip tie method

 

That's one way, but I find that mthod easier for installation than for removal.
I have a flat steel plate that's been set up to attach to my floor jack (makeshift transmission jack). I slide the engine over onto it. Others have used furnature dollies that have been set to hight by building a plaform on them, or a milk crate.
If you have a cherry-picker or overhead lift there's a drawing around here to build a fixture for lifting the engine out.

 

I thought about it.
But it's hard to get the shim out cause you have to hold the keeper ring down while doing it with one hand. I've seen it done.. lol
It turns into a 2 man job..

 

What bike do you have? I'm sure I read it before but I can't remember. Lol

 

Ummm... #0 flat blade screwdriver to pop the shim, and hemostat or magnet for shim removal. I've always used the wire/zip-ty method; no helper needed.

 

I was told using a magnet on them is a major no-no.. That the metal their made of is easily magnetized.

 

I had read that too but was later told that aagnet will do no harm. I think it even says in one of the manuals to use a magnet

 

Steel is fairly difficult to magnetize permanantly. The steel that is used to make the shims is far from ideal for making magnets.
The momentary contact from removing a shim will not magnetize it.
Even if a shim does get magnetized, it can easily be demagnetized by dropping it onto a workbench.


Removal by magnet is in the FSM, and has been practiced in shops for many, many decades.

Lol..
That kinda cracked me up!

 

So here's a dumb question?
What is the smallest tire that will fit a 19 inch rim?
This bike has 100/90 up front, and 130/90 out back.
I was hoping to get white walls.. But can't find tires any smaller than these??

 

A 19 inch tire.

 

Touche!

 

So I was decided to toss my drag bars on just to get an idea of what my bike might look like when I get farther along.
The headlight, and gauges have to go.
But I personally like these way better than the factory bars, and like the riding position better.
The mirror kinda makes it look less goofy though.. lol

 

Maybe bar end mirrors would work with those bars, if you can see them around your arms

 

I dunno?
I could see my son standing behind the bike with one factory mirror.

 

So I took my bike for a little ride today.
First ride since I bought it, (bike didn't run, and had been sitting 10 years).
Anyway. The throttle hangs really bad, then it idles at 2000rpm. Slowly back down to a normal idle.
What would cause that, a vacuum leak, or just my carbs are out of sync a bit??
