The drawing above is incorrect, so the answer would be "neither".First of all, here is a couple of pics of my bike. Pretty different from what it looked like last time I posted any pictures.
Now, about how much room should I have between my tire and lower tree on the springer? I dont have much at all when the trail seems to be correct. Distance from tire to tree is about 1-1/4 inch. How much will the old springs settle with the A65 motor in there and me (170lb) on it? How much will it travel up, going down the road?
This bike looks really close too. I just cant tell how close from any of the pictures Ive seen. Its in Dice issue 19
And my final question. I read lots and lots of different stuff on rake and trail. Most of what I read say go down from the center of the neck at the angle of the neck and mark the floor, then go straight down from the line down from the axle and measure the distance between the 2. I found another article where it refered to that as "fake trail". And this other measurement as "True Trail" Take a look at my drawing and you will see what I am talking about. What are your opinions on this? I put my measurments for both of these in my drawing. Here is the link to the article I read that in.
So I guess thats about it for now. Any help would be greatly appreciated.
The origin of the first line of intersection is through the steering head, not the fork legs.
Secondly, why are the fork legs in the drawing bent into a rake? Is this something you intend to build? Even if it is, the first line of intersection is always through the steering head. The second line is plumb through the axle to the tire contact patch. This holds true for measuring trail on ALL front ends.
