Need more time...
Hello all. This thread is continued from: http://www.xs400.com/forum/showthread.php?t=11453
Finally got my new bike on the road tonight, but not quite satisfied with performance. I finally got my headlight working with another relay (Thanks for your help XSChris). The petcock rebuild was a nightmare after all new seals from mikesxs. I kept getting a gas leak from that little slot in the side. I think the configuration was just wrong and I had to take it apart 4 times before that worked. I'm still not sure if its leaking into the carbs, I'm just glad its not leaking onto the floor at this point.
I took the carbs apart and did some maintenance. I adjusted the floats to 26 (1.023 inches) after reading a bunch of threads about it. I also backed the mix screws 2 turns. One of them was completely tighted which I found very odd, I saw a lot of others with 3 but I'm looking for gas saving over power for now. I didn't mess with the jets at all because I'm not too familiar with everything just yet. I built a monometer with a barbell and some hose I had lying around but I had some issues getting it balanced. First off, it doesn't like to idle without choke. I changed the carb holders but no dice. Once it warms up it will idle about 20 to 30 secs before stalling. I also noticed it misfiring a lot. While syncing, I noticed a small flame from the right side every time it backfired. Lastly, there is also exhaust coming out where the pipe and header meet. Tried to tighten and reseal but that didn't work. Could that exhaust leak be the cause of the misfiring? Also when I rev it up, it doesn't always like to come back down to idle. Unfortunately, I don't have a tach to give you the rpms. I already know that I need to clean the carbs, Which I hope to do when the weather gets cold. I guess I'm just wondering If the exhaust leak is most likely the problem or if its the valve clearances that I haven't adjusted yet, or if the carb just absolutely need cleaned before I can start riding it regularly.
On a good note, it ran like a champ revved up and going down the road. Its just keeping it running at idle thats the hard part.
I'd like to here your thoughts...
