Great write-up on carb cleaning and rebuilding

[16VGTIDave]

While not specific to XS400's, I found this write-up to be very informative. http://xjbikes.com/Forums/viewtopic/t=14692.html

And there is a link to another site with advice on jetting near the end.

Hope this helps answer some questions.

Long read but knowledge is power.

I'm bumping this thread because the link to factorypro.com with jetting advice is invaluable! I've been working through their tuning procedure and making great progress.

Go to http://www.factorypro.com and then click on the "Product Support/Technical Support" link at the top of the page, then on the "Motorcycle Tuning Tech" link, and then the "CV Carb Tuning" link........and then read, weep, study, and do....if you still dare to!

I've had an XJ700 for quite a few years before I got the XS400 for my son. I used that writeup a few times on the Xj700 carbs, it is excellent. It was so good I used it as a guide for the XS400 carbs as they are quite similar.
