He's in Texas and has decent prices on CB750 parts.

I've painted the frame, swingarm, and centerstand today and coated with a layer of hardener. So shiny!

I made an electrolysis setup for the tank; followed the instructions. I have a coat hanger for the node, I'm using salt water(fixing to run and get washing soda?), a 12V 6amp battery charger, and have the tank tank entry node and tank separated with a piece of rubber.

I've submerged and set it all up and am currently waiting to notice some difference since I haven't seen any. I thought it was a quick noticeable thing. Any ideas?

Well I'm gonna let it cook and run some errands maybe I'll see a difference when I return.

*fingers crossed*

Anyone know a good place to get a set of primary chains?

If you see bubbles its working.

Just what i was going to say. Here's the page of Honda OEM parts: http://www.dynoman.net/bikepages/sohc/oe.html

If you're that far into it, I highly suggest a new primary chain tensioner as well. We did some comparisons and the stocker will sack out over time.

I've hit another snag. I raised the bike up, took off the front wheel. Followed the instructions on disassembling the forks however I can't seem to get the alan nut on the bottom of the fork to budge.

It wont give at all, I've tried fattening my wrench a little but can't seem to move it and don't want to strip(round out) the bolt. I have no clearance to get a pair of vise grips in there either...
 
Any ideas?

I'm letting it soak with some liquid wrench at the moment to see if that and maybe some heat will help.

Grrr

Am I late, have you gotten this out?

My prior favorite penetrant was PB Blaster, but i've come to learn from this board that a 50/50 of acetone and ATF is better than PBB by a factor of 4.  Mix up a thimble and put it in the hole overnight. Also, that screw responds better to an air or electric impact.

While it is not a quick process you should notice some reaction right away.  Negative on the tank and positive on the electrode.  I mention this because there is some incorrect info floating around here.  Your small surface area electrode will require frequent removal for cleaning.  You will notice the amperage level drop as it gets loaded up.

Alright! Dynoman.net it is! I'll go ahead and order the tensioner as well. Like I said I really don't want to take that engine out of the frame for a 3rd time. I mean, it's not like it's heavy or anything...=P

On the electrolysis I figured last night after some experimentation and a few beers that the cheap battery charger from harbor freight wasn't giving enough power so last night with some friends I took my setup and ran it to the car battery and started it up and shortly noticed bubbles and oxidation. Something I hadn't seen at all with the charger.

On the forks I actually haven't touched except when I pass in/out of the garage I'll shoot a bit of PBB on the bolts. I'll take a whirl at that today.

I've seen something about acetone/ATF but couldn't figure out what that is..Aqua Teen Force? Oh no , A Thirsty Female? Automatic Trasmission Fluid maybe?

After the paint job - Might give it one more coat...

That dinky battery charger wasn't enough power for me.

This was the action I was lookin for

Gooh

Washing medium

I slid my camera into the water for you all figured it might look cool...

Crystal clear!

Rinsed throughly then dried with heat gun. 
Found out using the engine number and frame number that it's actually a 1974 K4. Whoops!


Well I ordered my primary chains and tensioner. Now to wait and get that crankcase split and painted.

[MCRider]

Yes the ATF is Automatic Trans Fluid. THis combo (acetone/ATF or Acetranny as someone coined it) beats all other penetrants known to man, mostly.  50/50 homebrew. Cheap.

Coming from a dyed in the wool PB Blaster fan.

I had just made a post with all the images linked however an error occurred, then said I had already posted. If you want to see my album of the entire breakdown process to present you may find it here:

I'm too lazy to go through and copy the image location for the tons of pictures I had just done.

Enjoy.

Thats a wild exhaust

Nice to see your other honda is helping you out there  its a rust gidder-ridder-ovver

Yeah when I posted that I didn't see pics... thanks for correcting it.  Nice to see the projects coming along

[pharr2305]

Yeah thats a 92 prelude so I want to get the bike up and running so I can take care of that baby. It runs like a puma but needs some aesthetic renewal =D It's the circle of life right? For Honda's maybe...

I received my new cam chain, tensioner, primary chains, tensioner, gasket set and oil seals in the mail as of yesterday! So today I will be painting the crankcase with engine enamel so I can throw those new pieces in! I feel like a giddy school girl, tehehehe!

Is this really happening? Sad thing is I've never driven a motorcycle before so I may have to wait before I can test it =\

But then again I drive a standard transmission on the prelude so I figure it might be similar. Add gas, release clutch, hang on? =P I will be needing to take a licensing class but I'm gonna have to wait.

Well as soon as I throw this puzzle together I'll be sure to update! Later!

If you've never ridden a bike before you may want to try on a bike you haven't just put countless hours and pennies into. That being said, good job so far, I need to get a cheap project bike and get started on this soon too. I just can't bring myself to change my current k4, it's in too great of condition to modify it much. I might even put stock bars and blinkers back on.

[razor02097]

Shifting on the left throttle and stopping on the right.

To get used to the clutch just play in first gear walking with the bike on a level parking lot or driveway and make un-powered walking turns till you get used to the weight and gain confidence.  A motorcycle training course would be good if you never ridden before.

oh, speaking of things that rattle out of my head, I had great results cleaning MickeyX's carbs with warm Simplegreen in a little saucepan I had no intention of ever cooking in.

It got all the annoying grease and crap off the outsides and the varnish out of the insides.

i use a crockpot i got for 2 dollars and fill it with simple green to get carb parts clean. i use the crockpot to put bearings, chains and anything else that needs to be lubed before assembly. i put cheap motor oil in and set it on low. i "cook" the parts overnight. really gets the oil into all the crevices (learned this trick at AMI from my BMW instructor) i "cook" chains like this overnight too.
