New Ural pulls to right

Woe unto you that bought the first model year of a major remake, perhaps this section can help address any 2014 and later model Ural "imperfections". Here's a special section for folks with the latest rigs to discuss 2014 and later model-related topics such fuel injection, 3-wheel disc brakes, hydraulic steering dampers, spin-on oil filters and other anomalies that don't belong on true Russsian motorcycle ;-P We've gone from using big hammers and greasy wrenches to needing computers and Ouija boards in order to fix our rigs.
Forum rules
Please keep this section specific to issues pertaining to 2014 and later models such as fuel injection, sidecar and rear disc brakes and so forth. Ask general or non-2014 and later specific questions in the main Hammerin' & Wrenchin' section.

New Ural pulls to right

Post by pbrowne » Sun May 19, 2019 7:13 am

I've had my 2018 Ural for 10 days and I'm almost ready to sell it! It pulls heavily to the right. It's dangerous to take my left hand off the handlebar because it immediately darts to the right. Even going in the opposite lane it will climb back over the crown of the road to the right.

I've increased toe-in in several steps, disconnected the sidecar brake,and put maximum pre-load on sidecar shock. I've kept lean-out at 1 1/2 - 2 degrees.

Nothing has made any difference.

The only thing that I have noticed is that the rear wheel points slightly right if I place a straight edge along the front and rear wheels. The front of the rear wheel has about 3/16" space to the straight edge, which is in contact with the rear of the rear wheel and both front and rear of front tire.

Help!!!

How close is your dealer? If they are close, I would take it back and have them make it right.


What do you have your toe-in set at now?

+1 on take it to a good dealer. Not a dealer, a GOOD dealer.

Otherwise,
Check wheel true. If a wheel is not true, you will have trouble aligning it yourself.

Set toe-in to 3/8" and leave it.

Use the rear rotor to give it 2 degrees of lean out, be prepared to add a bit more lean.

Ride, add more lean if needed, you should not need to go over 3 degrees.

You mentioned rear wheel not tracking behind front. Check your FD is mounted properly and there is no debris between the FD and swingarm. After that, I'd suspect the swingarm itself.

If none of that turns up a solution, time to get it to a good dealer to go over.

I had the same trouble with my 2008 Patrol. You should align the sidecar to the rear wheel track to solve it. Disregard the front wheel.

2018? So I'm guessing you bought it new? You're prolly a victim of all too common "improper dealer set-up" from an inexperienced dealer. For the money you got invested take it to a "good" dealership and have it set up right. It's a Ural so any future glitch is a possibility but for the money it should at least handle/run great for a sidecar outfit right off the showroom floor. It's normal for a new sidecar pilot to have to learn how to safely drive an outfit. Tricky enough with a properly set-up rig and takes time but what you're describing is not normal. Yeah sucks to have to bring a brand new Ural back to a dealer. But for the money invested it'd suck a lot more to get frustrated and just not ride it. Your mega buck investment entitles you to at least have right from day one!
For any prospective buyers out there...When buying a "new" Ural, dealer selection is CRITICAL.

+1. For now. Definitely a "inexperienced dealer" issue.

You mentioned that you're bumped the alignment. Since you know how this works, I'd suggest bumping in MORE toe-in and test ride it. Keep increasing toe-in until it's ride-able. THEN set up your alignment rig and measure it the set-up. If it turns out to be something ridiculous ( 1" + ) then start investigating.

The "old method" of aligning motorcycle front wheel/rear wheel involved stretching a piece of twine along the sidewall of the tires, taking care to ensure that the twine wasn't climbing over the tread block of one tire, but not the other (which would throw off the measurement).

EDIT
The front of the rear wheel has about 3/16" space to the straight edge, which is in contact with the rear of the rear wheel and both front and rear of front tire.
That would certainly induce some "right" steer into the machine; the back of the bike would want to swing to the left (think ladder fire truck with the tiller man in the back).

Being in WV, you’re just a stones throw from Heindl Engineering who are one of the best Ural dealers in the US. Make an appointment with them and bring your rig to get it set up properly.

My 2015 cT has always pulled to the right slightly and the rear tire only gives me about 4000 mi so I started re-adjusting. Went to 30mm toe-in (almost 1") and that didn't stop the right pull but it then started weaving back and forth during braking. I too noticed that there is a gap of about 1/8" at the front of the rear wheel with a 8" fluorescent tube laid across the front and rear tires. Reduced toe-in to 10mm but have not tested yet. May try aligning with rear tire only to sidecar. Will have to attach 8" tube to right side of rear tire to do that.

I had the Heidenau K-28 on there and I thought they were a longer mileage tire? Also just figured out why no contact at front of rear tire. Recently had Heidenau K-28 replaced with Metzler and that tire is 1/4" narrower at sidewall than the Heidenau. Needs a 1/8" spacer on rear tire to keep the straight edge in contact at all 4 points and parallel to the centerline of the bike. I think by aligning without a spacer will cause the front wheel to turn slightly to the left until the straight edge contacts the rear section of the rear tire. This will make the observed toe-in actually less than what is called for.

I have one of the magnetic degree gauges

It went in the box to take with me as a quick check on setup for the Ural.
