All depending on what uniform I am wearing, depends on if I go the north of the runway or to MSP airport. (Air force vs TSA)
Do you have a warm place to work on your bike? perhaps, I can drop by.
Common warning, don't run the vehicle engine that your jumping the bike with.
Okay, from the Tech Tab, one of the links was XS400 Manuals. first post in there is the 360-400 service manual, Page 25 of 34 has some checks to check.
from top of the garage, is a 45 meg for all 400's. Page 19 of 266 has specs for the coil. page 104 of that same book, has a break down of the test. now note: Bold this -- what bike is this segment talking about? validate that this is for your bike. ((Disclaimer))
mostly from bike to bike, the stuff is the same, but some things are not. always make sure that everything is right. weird my name is a original poster. Well I wasn't I just got tired of people finding the original post, and msg the author, and not read the 23rd post where he found a spot he can upload a 45 meg file. Totally worth while to have that post "Stickyed" and everyone can download it for free. There has been countless post on everything. Most of the time there is nothing wrong out side a few common fail things, (coil isn't one of them, getting them backwards is a common problem) I took mine to a yamaha dealer, and they tested them, said the spark was so strong, that they remembered it the next time I stopped in, 2 years later, and at a different site.
