    Next I replaced the flasher relay with an electronic one so fix the LED flash rate. Cylinder style from NAPA, ziptied in. Perfect fit and function. http://imgur.com/9ogzLOg http://imgur.com/vCBYtiw Then I started working on the tail light. Silicone EVERYWHERE! http://imgur.com/Bc7Gr0o...

    Now is the time to go ahead and mount the tank and finish up the front and middle of the bike. I had left the tank on a drip pan in case the petcock leaked a little and I guess it had tipped over at some point. This cause fuel to slowly leak out the cap and down the side of the tank. What I was...

    Next I needed to replace some of the dash lighting. While I was replacing two bulbs I figured I might as well go ahead and replace them all with LEDs. The gauge lighting is good but the idiot lights were INTENSE. http://imgur.com/Bxb5EIH I figured this would be a problem riding at night so I...

    I had to completely disconnect the front wiring to get the fairing off. http://imgur.com/a/bRVRx The original harness was all chewed up with splicing tools. Worthless crap destroys the old wiring so I had to replace portions of the wiring. http://imgur.com/BNQfMvG Pulled the wiring up an...

    So I'M BACK. I've been gone for military duty and busy at work but I did get some stuff done. I attended my first Vintage Bike Night at Schlafly Bottleworks. Some people really loved that front fairing. http://imgur.com/yqc9q4y On the trip home I noticed two things: 1. Part of the front...

    Update: Forks are done! I purchased from Amazon All Balls dust cap + fork seal kit. Part number: 56-115 Progressive Springs. Part number: 11-1106 I followed the directions posted http://www.cb750c.com/modules.php?name=Forums&file=viewtopic&t=244...

    amc49, I had two carbs hooked up at the same time to the home-made manometer. Not one at a time. I couldn't get anything balanced until about 1200 rpm then check it again at 1000 and they were still level. I'm fairly certain they are set. I did get the passages cleaned out after I took the...

    The manual says 8.0 ounces of fork oil. Is this the correct amount when using progressive springs? I took the forks apart and it was just sludge so I'm beyond due apparently. Waiting on the springs to come in the mail next. Flogger: Getting this thing road worthy is my main goal. Then...

    Update: Ordered some Progressive springs and some All Balls fork seals and dust seals. Should be here soon, I ordered them from Amazon. Couple questions: 1. Does the spacer come with these springs. 2. If not, what size length and diameter will I need? 3. If so, does it need to be cut down? I...

    Update: Front brake lines are all put together and new fluid in them. Makes a big difference. Checked the fuel level in the bowls and it's all good http://imgur.com/3IcOkia Then I sync'd them with a home made manometer. Took some brass and put some threads them to mount them to the engine...

    I also replaced the passage plugs too because they were all old and hard. I wonder if I need to blow out the passage under the plug with some compressed air. I don't think it's the float or needle valve because after I found the number two not working I swapped the float and needle valve with...

    Update: Master cylinder clean and flushed with new fluid. I'm having a local shop build some new brake lines for me. Replaced the faulty float valve and all the gaskets and the carburetors don't leak any more. But now I think I have a dead cylinder number 2. I felt the exhaust and they were...

    Flogger: I did buy a carb kit this time. And now I've heard of using brake cleaner to clean out the carbs so you don't ruin the rubber parts. Brilliant. I had no idea. I am going to go find some place to make me some new brake lines for the front. I can't believe they are clogged. I figured...

    Update It's been a weekend of failures. I tried the lemon juice boiling trick and either I didn't get the real lemon juice (said 0% daily amount of vitamin C) or I didn't cook it long enough (30 mins and moving it every 5 min) but it barely did a thing. So, I polished the valve seat for...

    Update: Wiring all made up for the coil relay. I determined that the best position is going to be by the battery. Under the tank would let the relay get too hot and it might short out. I found the operating temp range for these things is around 185*F so above the air-cooled engine is a no-go...
