Not tracking

[Obleo]

I have finally put my bike back together after my accident. Put about 50 miles on it and have an issue. The bike tracks to the left when I let go of the handlebars. I have done the alignment procedures three times per Delboys you tube videos. Checked rear axle alignment also everything’s up to spec. I plan to take it to a dealership unless someone on this forum may have a tip I maybe missing.

Hard to say what is wrong without seeing it or knowing what was replaced.

If you removed or replaced the front wheel, the wheel spacer on the left is narrower. Having them swapped around will definitely cause it to track badly.

You can check the forks by taking an aluminum I-beam type carpenter's level and putting them across the two fork legs. (You're using the level for its parallel sides, not as a level). It should contact each of the fork legs at 2 points, all at the same time. If it rocks at all, somethings bent.

You can double-check the straightness of the front fork tubes one at a time by loosening the bolts on the left fork at the upper and lower triple clamps, with the bike on the centerstand. You should be able to grab the fork tube with both hands and rotate it 360 degrees with no tightness. (You'll need to twist them back down in the clamps to the proper height). Tighten and repeat on other side.

If the fork tubes are straight, the triple clamps should also be straight - they can only bend if the tubes are bent/twisted. I've never seen bent triples with straight forks.

Very good practical points to check from Pekingduck as usual, Delboy has a good amount of information but some of it is just made up by him, i watched the video with the packing tape if that is the one you refer to, i would not check my bike using that method.

One of the ways i now find useful on the cb1100 is the method using a thin string, it attaches to one of the front disks, loops once around the rear tire and ends on the other front disk.
The front wheel needs to be straight but is not too critical if the lowest part of the disks is used and won't work with the bike on the centerstand which is in the way, i've tried it.
It has better accuracy instead of using the markers on the swingarm, you may just try this method;

If nothing can be found try riding on the other side of the road to verify it is not the camber in the road that allows for the rain to run off, here in nz it is very pronounced.

I'm no expert and certainly not a motorcycle mechanic. However, several years ago I experimented with letting go of the handlebars with the bike in neutral and with the bike in gear. The results were that the more engine brake a bike has the more it pulls to the left. As I remember the CB1000 may not have a lot of engine break so this is a doubtful solution. A bike like an Africa Twin that has a lot of engine break pulls to the left a good deal, when it is in gear, once the rider releases the handlebar.

Thanks for the replies , I know for sure rear axel alignment is spot on. Never took off front wheel, I loosened the top triple tree and lower triple tree on the left side ,was able rotate 360 degrees and no binding, went to the right side and felt a resistance, also was able to pull each fork leg up about 5 mm. If it’s quits raining this evening I plan to test ride it. Keeping my fingers crossed. As far as alignment with string, I have a surveying laser but couldn’t understand lining things up when you have different size tires front and back.

Severely worn tires?

If you felt a resistance rotating the right fork, it might be very slightly bent. After my Bonneville incident in February, with everything lined up as best as I could get it, I had a slight drift to the left as well, and a very slight amount of resistance on the right fork leg. The repairing dealer replaced the fork, and she's straight as normal now.

That’s good to know thanksG O
