Installed a toggle switch under the tank in order to eliminate the key switch. Pretty happy with how this turned out. I had to gut the ignition switch when I first got the bike because it came with no keys. No more pulling keys, knives or screwdrivers out of my pocket to turn off the bike!
I set the valves and then started over with carbs and syncing. There was a lot of slop in the valves. Carb adjustments went much better. Sprayed down carbs looking for air leak. Didn’t find anything but not going to be surprised if I find a leak eventually. So far no fast idle and bike is...
Following your advice. Set the valves this afternoon. Definitely too much play. Will re-sync. I did not replace any seals in the carbs. By shaft seals do you mean for the air inlet valve? I did not disassemble the butterflies. Diaphragms looked great. Drained all the oil and cleaned the...
Background
Me: I'm new to carbs. I'm new to motorcycles. I'm not afraid to fix it.
The bike: 81 xs 400 barn find. 6600 miles on the odometer. Completely stock. Did nothing to the engine except a couple of oil changes and fresh gas. (side note: I ditched the vacuum petcock in favor of a...
Looks much better. I like the bars and the new rear lights. Planning something similar with mine. Ditto on the tire question. I desperately need new rubber and also want more of a dual sport tire.
I brought home my xs400 in April, put fresh gas with stabilizer in it and started her up for the first time in 30ish years. Bike seemed to run great but I didn't have much time to mess with it. Since then I've started the bike 1 or 2 times a week and let it run for 10 minutes or so. I...
If your not concerned about keeping it original, it’s not to hard to make a plate to adapt to a 1/8 npt thread. Then you can use whatever cut off you like...
Got that too! I slightly overfilled with oil. Haven't run it since due to a leaky fuel petcock. Made an NPT adaptor plate and installed a new petcock yesterday. Hopefully will run it again today. I'm assuming it will take over 2000cc of oil since it has a new filter. I hope the oil level...
It's alive! After repairing a leak at the tank petcock and installing a new battery, I decided to see if she'd start. 3rd kick and she was running! Let it warm up and then changed the oil and filter. Yahoo!
