I’ve not had a lot of time to work on my own stuff lately but stayed up late the other night to install the front end on the sidecar rig. Before it was hard to turn but now is too easy! No wobble at speed but the slightest touch of the bars makes it sway like a jeep with a lift kit? Tubes used were .188wall dom so I don’t think it’s due to weak tubing? If I did not have enough trail I should have a “shopping cart” wheel wobble but I don’t? Road crown cannot even be felt anymore and passenger in chair makes no difference, sooooo easy to turn just VERY sensitive? Also when flying the chair there is a wobble but I’m assuming it’s because I’m on two wheels and geometry is set for three? This just goes to show the more you know the less you know, I’ve got a lot to learn. p.s. Skull, that is an awsome rig! Have not seen that one before, looks stable as hell!

gordon do you have a steering dampener mounted? that would help slow down the steering a bit

I've stated earlier that I know jack about sidecars, so please don't forget that!
The rear looks kinda low in comparison to the front, maybe longer shocks (or some kind of a riser) might load the front up a bit more & help you out?
I don't suppose you weighed your wheels footprint with the old configuration so you could compare front/rear bias....
Also the front tyre could be making it skittish, perhaps a squarer profile might sort it?

It's small (from Mikes) do you think a heavy duty one would do the trick? If so from what? Like one used on a old VW or something? p.s. if you click on picture you can see it mounted.

Yamaman, I totaly agree a flat profile tire would be so much better but I'm running 130/16 front and rear now and having a hell of a time finding flat profile tires in that size. Coker tire has some antuiqe car tires that might do it but I would love some modern rubber. I think I could get a 175/60-16 on there but can't find any on the net? Also if I raise the rear it will reduce trail in front and make it even more unstable (I think?) thanks for the input guys

Thanks Yamaman I did look at your other post and clicked on link but thought it was only the triple duty that was flat profile and they don’t come in a 16” This time I looked closer and see that the 16” they make is almost flat profile so might be just what the sidecar doctor ordered. I’ve never seen those here in the states before so may have to order from UK. Thanks a lot for taking the time to get those links for me I really do appreciate it

No drama at all. If it wasn't for you posting 3rd wheel stuff, I'd still be living in ignorant bliss about the whole thing.....There was never a sidecar in my lottery dream before.........Now the lottery shed is going to have to be bigger.....Or a second story

Gordon
talking with charlie on your car set up, again he said his stuff worked better with flat bias ply tyres. But added this fuel for thought. Rear springs rates. He said that forget what is recomended for spring rates for solo machines, go heavier. It will he;p transfer some of the load to the steering. Also front spring rates will change handleing characteristics. Dont know what your running either end, but may play a big role in what you are experianceing. He didnt say to go either heavier nor lighter on the front, just that it does alter the handleing. What did you experiance when you put in the progressive springs on the stock forks? Of course that may not be the same with useing coil overs as you are now. But may need to either lighten up or or stiffen up. Also all shocks are not created equaly. The cheap oil shocks such as the ones mikes sells have small damping rods, I beleive are 3/8", compared with say red wing hammerheads at 1/2", means more damping action. Also more money. Damm you got to love those old 70 plus year old guys that played with this stuff back in the days when there was very little technology. You should hear his trike tricks.

I read a couple of places that scooter tyres are a good thing for sidecar steerers....?
www.tyresalesuk.co.uk/...=16&Page=1
I'm sure you already know, but when using a (cross or bias ply anyway, not sure about radials) rear tyre on the front, you should have the directional arrow going the wrong way. Just a safety thing, shouldn't effect handling, stops the tyre coming to bits under brakes.

Love the pictures! I can really relate to the one in the snow....the foothills up behind my house are white on top, and it is almost time to go play, and take along a rope to wrap around the rear tire for traction.....sidecars are so much fun in the snow!
Great shots!

gooding look yes a heavier dampener should stabilize the steering, is there a lot of difference in the steering between slow speed and higher speeds? don't know if you found these sites

Hi Jayel, The only thing I can tell is the faster you go the more “twitchy” it felt, very slight touch would have rig twitch not wobble if that makes any sence , before I had to put some muscle into it. NO front end wobbles at any speed (only went to 60 or so). Before I would have a wobble on take off to 8-10mph or so but now nothing. Also I could not take a hand off bars at speed without feeling the wobble come on but now can take both hands off bars at 40mph and is like a car with perfect alignment, not even a shake. I think with the upgrades I’ve done ,better dampener and flatter profile tiers it will be fine. So in short no wobble at any speed now, very easy to turn (too easy) with or without passenger and even up hill left hand turns are a breeze (left up hill most force needed on bars with sidecars) it was just the “twitchy” steering on strait ways at speed that had me wondering? I have the handbook but will have to sign up to yahoo to see the other link, thanks Jayel

scott;
when you put on the front brake does the bike rise up in the front as a earles does? Thats something i always liked about them no dive when on the brakes.

It is a combination of the way the brakes are mounted to the axel and not to the swing arm, and the fact that the front axel and pivot point of the forward facing swing arm are on the same vertical plane that gives this effect. If the swingarm pivot was below the front axel you would have dive during braking, if above the front axel you would have lift during braking, but on the same vertical plane you have neither. Hope this makes sense?
