I like the post (it might be in Tricks and Tips) about using an old 3.5" floppy disk and cutting it to fit the floats at the specified height. It's clever and seems like it'd be quite accurate, especially for old bent up floats.

+1 on the caliper and the slidey ruler (technical terms, meh!)

I'll vouch for the floppy. Did it for my 750 and it worked nicely. Really interested in your results with the Morgan as my Motion Pro is performing strangely  :'(

Not mine but this is what you'll end up with  ;D


Quick edit: Oh man. That sucks, you know, literally. The Morgan costs as much as I paid for the Motion Pro and NO FLUID. Mistakes were made on my part I think  :P

OK.  This is my first time digging into a muffler.  My anual says to take out the baffle and scrub it with a wire brush.   I removed the tip from the muffler, now I see this...


It seems like they must be talking about that metal thing protruding, but when I grab it with pliers, it doesn't really want to come out.  Seems like it might even tear off that metal if I really give it a yank with pliers.  What gives?

if you have a round wire brush on a stick (dont know the technical term , but it looks like a big pipe cleaner) 

its most likely just corroded in place, IMO removing it , isn't a biggie , unless it's a glass pack and you wanna redo the fiberglass

OK.  Thanks Spikey.  I picked up some brushes at Harbor Freight.  And did a bit of scrubbing followed by blowing it out with the air compressor:


BTW- Spikey, I saw your bike for the first time last night.  (Both iterations)...  That is totally badass.  Excellent workmanship!

The exhaust pipes are putting up more of a fight than I expected going back on.  Those little metal collars that go on the end of the pipe weren't wanting to slide on in.  I guess I should probably take a wire brush to them to remove the surface rust and use some assembly lube to help them slide in?  Good idea?

I fiddled with these things for about an hour...  I would just about get one, then the other would move and the collars would fall out on the floor... repeat...  trying to manuever the muffler end up into the right position and wiggle everything to try to persuade them to slide in...   I finally walked away and decided to tackle it later.  Not before vowing that when Santa brings me some new exhaust pipes, those old ones are going to meet the same fate that the fax machine did in the movie "Office Space."   Oh yeah, they aren't just going to be discarded...  i am going to take a nice big sledge hammer and get medieval on their ass.  ;)

No No now Tim..What you wanna do is get biblical on thier a$$.

Like old testament....I'm thinking Joseph....sell them into bondage.

Trade them later for something ya really need.

As for getting the pipes on.....clean up the rusty studs....

Put on all four collars....Then do one clamp/ half moon at a time.

Start on one side and work your way across.

Sometimes it helps if you put the muffler bracket bolt in loosely



If you have the 4-2 do below.

Do one of one side then do the other of that side.

Treat them as two seperate pipes.

Assuming it goes together similar to a 550...

Review how those split collars fit into the flanges.  There is a step in the casting to accept the collar shoulders.  Important they go in that step.

Also block (or wire) up the mufflers so they are near where they mount.  (They still have to move fore and aft for mounting.)  If you let then hang from the exhaust flanges, they will deform the crush washers/seals, and they will leak.
The headers have to go into the head at the same angle as they will ultimately mount.

It is 2:00AM, and I have to be at work at 7:30, so not much time to post.  But, She is back together 100%!   New spark plugs, filled back up with oil.  More details tomorrow:

Moham thanks for the props.  The plan definitely calls for the bike and myself BOTH be moving down the street together, screaming or not.

Spikey-  Looking forward to you teaching me how to weld on my next project bike "Chopper building for Dummies."  That won't be for a while.

Hoodelly- Keep reading, there may be a carb issue you can comment on...

Fastbroshi/ Kghost- Little by little was indeed the ticket on those pipes.

TT-  Thanks.  Hanging the muffler end by a wire at the proper height helped alot.

Tim-(Kghost)- You talked me down once again. Thanks.  It's always nice to apply strategies from the Good Book.  I, too am a fan of the Holy Bible...  read it cover to cover (and I read the cover  ;))  BTW- as I recall, didn't Joseph's brothers kick the crap out of him and throw him into a pit before selling him off?  I might feel better if I didn't skip that step.

Matt (OldRusty)- Snow?

Dagersh- Thanks for checking in.  Hopefully we'll be cruising soon.  It has been a very satisfying build.

OK-  Here is what happened after the final twist of the wrench last night...
I put the freshly charged battery in, switched the fuel petcock to "on", opened up the choke and hit the starter button.  And start she did.  Sounded a little throaty, but less clangy than before.  It didn't stay running for long.  After a brief time, carb number 1 and number 2 took a healthy pee on the garage floor.  I shut the engine down and turned my attention to the growing puddle of gas under the bike!

I imagine (and hope) this is related to my failure to do ANY kind of float level measuring prior to installing the carbs?  Well?   :-\

A bike that has been sitting for awhile, especially if the carbs dried out, many times you can cure a leaky carb by simply rapping on the bowl with a screwdriver handle.

how about 4 bucks at any hardware store (just make sure you get the metric one)



Found one similar to this for 89 cents at Harbor Freight

I heard there's a chance of snow across Dayton to Columbus beginning of next week from the system that just took a dump in Nebraska.

Cheers to Art on this one.  I tapped those carb bowls a bit and it starts now without the overflow.  I have a video clip...  Not sure if I post it the same as a pic?

Now about that clip:
A) No comments on the pink camera strap (it is my wife's camera  ::))

B) I didn't think to have the choke open at first, so that is why it wasn't firing up at first.

C) Now, I had to keep giving it throttle for it to run.  I guess I need to richen the air fuel mixture?  Now without digging out my manual, I am thinking that is accomplished by fiddling with these?

I think I started with the screws turned all the way in and then backed out half a turn.  Does it richen the mixture the more turns I back out?

From the CARB FAQ

http://forums.sohc4.net/index.php?topic=5410.0;all

What happens when I turn the airscrew out - richer or leaner?
If your airscrew is on airbox side of carb, turning out will lean mixture; opposite if airscrew is on engine side of carb.


I have the same gas overflow issue on my 350.  Tapping the bowl will help mine sometimes, but it always comes back.  I'd keep an eye on it.

I agree.  Tim inspired me, another self proclaimed moron, to attempt my own build.
