My 81 runs at 5,000 rpm going 55 mph. That appears to be right in the middle of the power band and has decent torque for acceleration and passing. I did not change any of the sprockets so it is just how I got it.
Wolfe 11B I assure you I am not imaging the improved running with the higher octane from my local gas station. Blended crap or not. It is possible that after sitting dormant for 5 plus years the engine has cleared itself somewhat after a 200 miles of running but it still ran a little...
In the first picture it looks like there is no hose on the crankcase vent port. Or at least it is not visible. My 81 has a hose on that vent port connected to the "H" hose from the carbs to the individual air elements.
Just a quick update on my 81 xs400s. I got the rest of my carb parts awhile back and put in the new needle and seat along with bowl gaskets. New plug wires installed and the bike runs good. Made a couple trips to work with it (about 30 miles a day) and all is well.
Then I decided to go to...
How it looks is a personal preference most of the time so thats a difficult task to know what your looking for. I found one online from National Cycle that I like allot. I got N2590-01 Deflector Screen. Fits my 81 Special great. Won't stop all the wind in the eyes but sure makes it more...
I bought a small wind deflector I liked online instead of the larger faring type. It keeps the wind out of my eyes and shoots it over my head even though my line of sight is well above it. So far so good. Just rode about 30 miles on a test ride today. It is in the pictures I have posted...
OK, That's good to know. I wasn't sure if a rim made for tubeless tires was finished well enough on the inside so it wouldn't shred a tube when installed. I haven't removed the tire yet obviously.
OK, I did the compression test with the carbs removed today after getting home from work. They both averaged 125 psi so I feel better about that. I am waiting on carb gaskets for the bowl this time so it will be a few days before it goes back together. After it gets running smoothly I will...
This is a concern of mine that there could be some damage. I used a accurate compression gauge that screws in the plug hole and is sealed with an o-ring so it should be reliable. It has sat idle for at least 5 years but I really don't know much else about its history. The last itme it was...
I got this 81 about a month ago. When I got it home the crankcase was full of gas. The previous owner had tried to get it running in preparation for selling it. I am concerned that in the process he may have scored the cylinders a bit. On the left side I get 78 psi dry. On the right I get...
I have not been able to locate the points so I can check the gap and condition. The LH side of the engine does not really resemble the pictures in my manual. Above the plug is what I feel is the correct area but I have a single phillips screw holding a rectangle shaped box on the side. There...
On my 1981 model the turn indicator switch goes back to center immediately but the indicator continues to flash until the auto cancel stops it, or you can push inward on the switch to cancel immediately.
