Leading links or Triple Trees?

Postby Sidcar » Tue Oct 02, 2012 4:24 pm



I've now done about 500 miles on my Wing outfit. I celebrated by changing the oil and filter, only 500 mls but the oil was black, and the rear hub oil. Fourth time I've changed that and it's now coming out clean.
The Wing now runs well (pleeeeeenty of power!) but I do need to do something about the handlebar wobble and heavy (as lead) steering.
The choice seem to be either leading link forks or new (EZ-Steer) or modified triple trees. I would hope either would cure the "wobble" because I can't see how to fit a damper without removing the trim around the front wheel. The chances of a set of used links or t/trees coming along seems very slim and I'd like to ride, and enjoy riding, the rig now so does anyone have a preference or any experience of the above. Personaly I'm leaning towards EZ-Steer:
1. Even with shipping charges they're about £400 cheaper than leading links.
2. They don't alter the look of the bike, which I like very much.
3. The front tyre is only 500 miles old so I'd like to keep it.

All opinions welcome.

My 85 Aspy had a wobble to it oo. All I did was grab the bars a bit firmer and that was it. The guy I sold it to complained about it too. I showed him how I just grab a hold of the grips and boss the bike. It may be more than that in your case but not so much with mine. Two pennies.

That's what I'm doing at the moment but the wobble is so strong I daren't take a hand off the grip even to wave to someone and it's doing my arthritis no good at all.

As for who's boss? it could go either way.

You may want to go with a 4.5 degree rake that is also used on trikes.
Your bike retains all the original front end parts.

Thankls for the comment. Is the EZ Steer rake adjustable or is there a choice when you buy it?

I believe they have two different versions with different (non-adjustable) rake angles on them.

The easy steer looks like a quality made item.

My experience with a sidecar is very old (back in the sixties), but even then I had to learn to live with the violent handlebar action. If I took the sidecar off, the wobble disappeared. There is obviously something to do with the weight distribution being placed on the sidecar wheel, and taking it off the frong wheel, which makes it lighter (a bit like a shopping trolley at the supermarkets). You get a trolley and it works perfectly, but put a load of groceries in, and it takes a mind of its own. You often seen those trolleys with wheels go everyway but forward, and I think that it is because the balance is not distributed evenly over the wheels. Perhaps someone with a better background in engineering could add to this.

The cure? I never found one, but my forearm and bicep muscles certainly grew :D . Not sure if you see this as a way of bashing through your arthritis. It might mean a trip to a sidecar manufacturer to see how they overcome this problem, as I believe it is common. Do not suggest an answer, but use your ears and mouth in that ratio, and you could learn how to overcome the problem, with the least amount of pocket lightening. I would not be jumping into the triple trees or other solution, until some others have addressed the problem.

Of course there is another way of tackling this problem, cure the arthritis and who cares if the bars wobble or the steerings's heavy.
The medical profession don't seem to offer much hope (loose weight, I'm only 135 lbs now, and eat healthy) and I've tried most of the "snake oil" options (including Emu oil, Redial).
Triple trees is probably the simpler more reliable solution.
Got to do something, on the main roads and Motorways (boring) it's ok but down your average English country lane it's a real, shoulder renching handful.

I know it's a case of curing the symptom rather than the cause, but if you can't figure another way of doing it, perhaps a hydraulic steering dampener might add enough resonant resistance to the steering system so as to stop the problem.

Thanks for the comment Wingman (and thanks for the EXCELLENT website, don't know how you find the time to do it but as far as I'm concerned it's time very well spent).
This L/link v Triple Trees is just about doing my head in. Each has it's pros and cons. Links are stronger and more versatile (I could fit a car wheel and tyre) but oh aren't they ugly. T/trees are cheaper (£400 is not a sum to be sniffed at) and I get to keep the good looks of my Wing.
Perhaps I'll put two names in a hat and go with the one I draw out, or maybe run a pole on this website and see which gets the most votes.

Regards

Sid

Well the bullet has been bitten and I've ordered an EZ-Steer kit from DMC Sidecars so hopefully Tendonitis will soon be a thing of the past. I'll do the fork seals at the same time.
Can't wait.

Anothertrick is to tighten the steering head bearings 20% tighter than the factory specs. That will not damage them but the increased friction will reduce the oscillation. Have you checked out the sidecar sites ? In US we have www.sidecar.com and http://autos.groups.yahoo.com/group/SCT/. Also the UK sidecar club is great. Doug

At the moment I'm still waiting for my EZ-Steer kit to arrive, 2 weeks and counting so far. While I'm waiting I'm fitting new seals in the fork legs.
I've got 2 posts running on the USCA website and had some useful advice.
Hopefully extra torque on the head bearings won't be needed but I'll keep it in mind.

Sid You will love the power steering afforded by the triple clamp change but you can fix the shake with proper toe-in adjustment. The only bike model I have trouble with is the stock GL1200. I built an 84 standard and used a set of Unit forks with great success. No damper and no shake. Assuming everything else is tight, no play and wheel lead is correct toe-in will solve it. One other thing I find when putting a sidecar on a new (used) bike is that some two wheelers wear the front tire so that if you run your hand over the tread it feels lumpy. The only fix for this is a new tire. Adjusting the steering head bearings for sidecar use is different than two wheels. Put the bike up on the center stand or jack with the front wheel off the ground. Tighten the steering bearings until you feel a slight drag on the steering. Usually about 10 to 15 ft lbs more than stock. I know it can be hard with the Watsonian sidecars but wheel lead should be 10-15% of the wheel base axle to axle or as close as you can get it. The Champion escort and Daytona work great with a six inch lead. I have hundreds of thousands of miles on GL1500's with sidecars and they are a great tug.

Trees arrived and fitted, what a difference!
Steering lovely and light, no wobble whatsoever.
Customs and Excise stung me with fees and import duty, bless them, but the results are worth it.

Rain or shine,it's forecast rain, I'm out on it tomorrow.

Steering will seem quick at first. Key is to relax on the bars and not over correct. Have a great ride.

Did about 50 miles yesterday and given the amount of flood water we had to ride through or divert round we were lucky to do that. If it doesn't stop raining soon this island's going to sink. The bike's a real pleasure to ride feather light steering, no wobble and my new heated grips worked a treat as well. Too well in fact, on the top setting my hands were being roasted, I had to turn the heat down two stops.
In fact so good is it too ride I've been riding it too and from work and sod the rain.
