Hello fellow xs650 members, This will be my first post and sure of many more as I just dove into a 78 XS650 about 1 month ago. I enjoy reading all of the info on this site related to the XS650, but like any new xs650 new owner I have problems and to stubborn to ask for help..lol...Sure the PO said everything was great and it ran!(BS) I have stalked the site about 3 weeks trying to learn and read all the info I can find on the bike(at least 15hr a week), but I'm a bit unsure about where to go next. Well let me give you a brief description of what I have done and what is going on. 1.) Got bike home and checked Cleaned(changed) oil, slump,and tank(rust) Fuses 20A(Great beep w/ M-Meter) Replaced spark plugs(no spark to begin with and still no spark) So my question is how to properly test a 78XS650 coil(s)PLACE mm ON WHAT SETTING and WHERE TO PLACE mm ON COIL OR POWER-SOURCE FROM bat), b/c that's the next step of checking for spark(correct)? From what I have read I place the MM..+ on R/W(from Bat) and MM..G on orange from battery no Volts( only volts I have are 12.9 at battery!)( If I place MM on coils where they are solder next to plastic or hard metal I get 4.2 on MM_)Thought I gained knowledge about it though a great search of info from goggle but from readings I find aren't enough for me! That's all the info I can think of at this moment but if anything comes up I can explain, THE PROBLEM............!!!!!!!!!!!!l. THX IN ADVANCE FOR THE HELP! Info I have is CLYMER- Service,Repair, Maintenance(book).....So not much b/c its does not go into detail!
