Changed out the bars to the EBR triple clamp with clipons, over the last couple of days. I did low side at one of my last track days about 1 month ago, but didn't notice anything when I ran the next day.

Noticed a slight pull to the left today, first test ride after triple and clipons, when I let go of the bars.

How do I measure if something is out of alignment? From the top of the triple to the top of the fork are even and from the bottom of the fork to the triple are even, what else can I check?

Tires are not overly worn, but if anything are more worn on the right than the left. Also it wasn't a crowned road causing the pull.

Two long 2x4s, one each side of the rear tire. Measure both sides of the rear to align the 2x4s. Measure the very front to make sure it is the same as the other two measures. Now measure the distance from the bottom centre of the front wheel. Both sides should be equal. Handlebars should be square.

easy fix is to loosen all the top tree pinch bolts and stem nut together and then retighten. test ride. still there, align.

Where are you going to find two straight 2X4s these days?

flourescent light bulbs work for aligning better. a straight 2 by 4 is a rarity

A string and 2 sticks works for me.
If the string is tight and touches the front and rear of both tires, you're good.

A tight string can't touch front AND rear of both tyres at the same time due to the different tyre widths it should touch front and rear of the rear tyre both sides and then be equal distance from each side of the front tyre.

OOppps didn't think of that Kev.

Same gap front and back of front tire or a proper spacer.

I haven't thought about alignment since getting on my first XB since the rear wheel is always in the same place.

The string method is a great way to align the rear tire on a chain bike....doesn't really help much on our non-adjustable rear axles, other than I guess it can tell you if it's outta whack. It won't really tell you if the front is out of alignment, as the tire could be straight but not the bars etc.

If it were me- I would check the rear using the string method. Once you find out that it is straight, I would loosen up the triple clamps, wriggle it all around a bit to get it to settle in and re tighten.

Loosened it all up and retightened. Seemed to work.
