    new issue: idles perfectly but on throttle, pops loudly and fires unevenly

    so two nights ago, i may have fixed it because i was able to ride it last night. i guess my initial theory was correct: moving from 1000+ foot elevation to 86ft elevation was too much for my little carbs to handle. so i tightened down the fuel/air mixture screws and it worked! when i tried...

    new issue: idles perfectly but on throttle, pops loudly and fires unevenly

    hey! these forums have helped me do so much work on this bike over the past year or two and i had it running beautifully. but i recently moved to CA and brought the bike in the back of a moving truck. there was atleast one giant bump i hit where i thought everything in the back of the truck...

    Carb Adjustment

    i just emailed mikesxs asking about jets and such for my 80 (or 81?) xs400 with the B34 Mikunis. they emailed me back and said NONE of their parts will work for the 400!!!!!! i emailed back and said i thought they were the same carbs, but here was their response: The carb bodies are the same...

    fork seal test?

    I had the same issue. super squishy forks and oil actually leaking out the seals and down the side of the fork tube onto the floor. and I wanted to install some gaiters! it was actually a really simple job. the hardest part was getting the little C clip out of the top by myself. managed to...

    Progressive suspension upgrade

    last weekend i replaced the seals and springs in my 1980. was rather easy, except for getting the little round clip out and back in the top of the fork. that took some time and effort (without a vice). i added 15w fork oil and some generic seals i got at a local shop. these are the springs i...

    I messed up my front drum brake. How do I adjust it?!

    when i got my xs400, the PO said it had new front brakes but he ran it without the lever because the brakes would stick after squeezing. you had to manually open the linkage by pushing on it. so last weekend i rebuilt the front forks (they were leaking and super squishy), and also took apart...

    where to but fork gaiters

    i just ordered the same ones from Dime City that @riotten22 mentioned. fit great. i have my forks lowered 22mm, which slightly compresses the boots and makes them not quite "straight," but i dont think anyone but myself would notice. the upper and lower openings fit perfectly. i did not...

    what is this copper/brass tube sticking out of the engine?

    yep, that's what it is! thanks! now that I know what it's called, i was able to find some posts on it. found one from a few years ago where a member on here machined custom plugs. just messaged him to see if he is still making them.

    what is this copper/brass tube sticking out of the engine?

    so i am wondering what this tube is. it is on the upper right of the engine, just to the inside of the valve adjustment cap. 1980 xs400 g or sg, i think looks to be made of copper or brass. the end looks like it should be open, but the PO filled it with some sort of rubber caulking (possible...

    Spark Plugs

    those are the plugs I'm running on my '80. I gapped them to .028 - .03. fired right up!

    Finally making my introduction.

    your build is sorta like mine! what tires are you running? they look like the Firestone champions, but a bit different. we're having an 80 degree day today in AZ, so I'm about to go out on a ride myself!

    (intro) new owner of chopped 1980 xs400!

    yep, checked the rim and its 2.15. does that mean the tire is going to go flying off? :yikes: as for front fork stuff . . . none of that dime city stuff is xs400-specific? they have xs650 springs, will those fit? is that even something that needs to be replaced? or can i just put new seals...

    (intro) new owner of chopped 1980 xs400!

    I actually just measured the width of the rim. is that not what determines rim width?

    (intro) new owner of chopped 1980 xs400!

    also, the owner of the shop who sync'd my carbs said not to get the matching front wheel because of handling issues.

    (intro) new owner of chopped 1980 xs400!

    yeah it's 5.0-16 on a 3.25" rim. the photos seem to have a bit of a fisheye effect, making it look bigger. I haven't notice much of an issue with handling because of it. except I went to tight in a left turn and scuffed through the exhaust wrap. I had to tie the dangling end to the frame so it...
