I need some help setting the timing on a 78 XS400 guys. I followed the instructions in the manual but the timing seems to be still completely off. I loosened points A and attached a test light to point B. I spun the motor over so that it is aligned at the "LF" mark. Before"LF" and after the line...

I know it is an easy job but I was uncertain about acouple of thing when I did it so I though I'd write up a How to for those who know as much as me (i don't know much :)) If there is anything i should change or add please let me know. Here is the link to my new blog...

Ok, so I def want to upgrade to a more modern fork setup, partly for looks, partly for stopping power/performance. I recently snagged a good deal on a set of 2004 GSX-R600 fork tubes. So here’s what I'm thinking. I’ve been researching triple trees and bearing and tube diameters and crap so I...

Hi people I have decided to start using Shell 20w50 API SH rated oil in my '82 Seca DOHC motor. Yep, its a car engine oil and it meets the owner's manual's recommended rating (20w50). I know that some say "JASO MA only" and some say "Anything is fine as long as you change regularly". I...

Ok, I made one of these manometers instead of the usual ones a lot of the others have posted because there is no risk of sucking fluid into the carbs with the bottle style. What you need: -2 glass snapple bottles -10-11 feet of clear tubing about 1/4 inch od and 3/8 or so ID. - two rubber...

I have just built my first bike last spring and dieing to ride this **cker, only the crappy charging system keeps crapping out. All summer every time a left the house i would load up the ramp and straps in the truck so the wife could come me up. Now for my question is there any up-grade to the...

Hey Hardtailed - I cut the front springs of my '78 xs400 about 2 1/2" to lower the front end. I read your comment here about adding spacers. I didn't add spacers - should I? I haven't ridden the bike yet. What should I make the spacers out of? thanks... rmal
