Go to the links section on this web site and click on the "Diy's and how to" link. Then select the "Cleaning the Hitachi Carbs" link. Study that for a few days and then let us know when you plan to start. We can walk you through a lot of glitches you may encounter. I also have acarb cleaning guide that can be quite helpful. If you want I will PM that to you. Just ask for it when you are ready.

 

i just came out of the lounge, where i found a step by step put on by rickomattick i believe. very helpful. as the season comes to a head, imay not get to it till winter. but it seems to be something i can do........... however ,i also put a header on the bike too. i have read some of the other chat and accordingly the jets may need to be changed also???????????? which poses more ?'s what size, bigger or smaller? so far i'vemanaged to do all myself ,but technical is NOT my bag

 

When changing to a 4 to 1 header you will always go to a larger jet. Most headers come with a chart for selecting the jet size. Post a question similar to this in the XJ modifications forum and they can answer more accurately.
