Here is my 1980 CB750F: Some of the mods include: LEDs Idiot lights mounted inside the upper fuse box Single red LEDs mounted in mirror mounts that flash with turn signals Custom aluminum battery box Two-up seat. Removable cowling to cover rear passenger seat Star pattern drilled rotors DIY...

Thought I'd share my seat for those who want to carry a passenger and still obtain that bubble hump look. I made the main part of the seat by carving a mold out of florist foam, covering it with metal tape and then fiber glassing over top. To create the removable seat cover/cowl I did the same...

There was quite the discussion going on at cb750f.com in regards to cafe-ing bikes especially the cb750f. Here are some posts Joined: Mar 12, 2010 Luba, I have not intentionally singled you out. Your bike is an F, although not my cup of tea, it is still an F, and belongs here. I however DO...

I planned on making a fiberglas seat for my XS400, as I could not find any off the shelf that would fit and I was trying to do this on the cheap. I also didn't want to cut any of my frame and wanted to leave the battery, internal rear fender and everything else pretty much stock. This meant...

I am getting ready to paint my tank and seat and am planning on doing it DIY style, like the rest of the bike. I got some quotes for automotive paint and it looks like I would be in for at least $150 for paint alone. So instead of shelling out these $$$ I am looking at a rattle can job or am...

am having an intermittent noise sometimes when I switch the ignition of my bike on. It is an 81 XS400. The noise sounds like a large puff or release of air. It only happens sometimes and occurs about a second or too after I turn the key to run. It happens before I start the bike. It also seems...

Hi All, Just wondering if anyone has tried to make a fiberglass seat by first cutting out a bunch of "ribs" to follow the profile of the hump they wanted and then stretching fleece over this and then applying the fiberglass and resin. It seems that it would be easy to draw the seat up on the...

Here are the rearsets that I have been working on for a while. You may have seen my cardboard mockup post here. http://dotheton.com/index.php?topic=7056.msg60372#msg60372 I finally got around to cutting out the rearsets and mounting them. The only change I needed to make was that I got rid of...

What is the best way to go about filling in the holes left from removing the tank badges? I removed the badges and now just have the metal attachment piece and the indent in the tank. I didn't think that filling in such a large hole with bondo would be a good idea. Should I use some JB weld to...

I am replacing the spark plug caps and high tension wires on my XS bike. The service data sheet says that spark plug cap should have a resistance of 10kOhm resistance however the new caps I bought have a resistance of 5Kohm and I am having a problem finding the 10kohm caps. Any one know if there...

I am currently in a yamaha XS400 build and have had a relatively painless job in finding parts for this bike thanks to MikesXS.com. However there are a couple of bikes for sale in my area that would make another good project, one is a 1981 CB650 and the other a 1980 CB750 F Supersport. They...

Hi guys, I was wondering what most of you do with your cables and lines after you lower your handle bars. I know I can order some custom length steel braided brake lines on e-bay or get them cut at a shop, but I was wondering how I can go about shortening my throttle and clutch cables. Is it...

I am planning on building my own rearsets for my XS but was wondering if you could recommend how I should go about mounting the rearset, specifically the pivoting shifter and brake lever. I plan on building a bracket and welding it to my frame. I then plan on having the lever built from...

Hello, I just got my clubman/cafe bars last night and started to mock them up on my bike. It is a Yamaha 81 XS400, the original bars were the pullback type and look like the photo below: When I pulled off the original handlebars there was a 12" long weighted cylinder in each bar. The weights...

I was thinking about building a fiberglass fender by copying my existing front fender, but have not used fiberglass and dont know if this will work, here is what i was thinking: My current front fender is chrome and pitted very bad, so i either need to fill in the pits and paint it or replace...

I am going to start to build a fiberglass seat for my xs400 but have a couple of questions. Here is what I have so far: Styrofoam foam for making the mold Fiberglass matting, cloth & resin I can not get urethane foam and am aware that applying my resin will just eat the styrofoam. Going for...
