austini Posted April 12, 2019 Report Share Posted April 12, 2019 Hi Guys and Girls, how about some talk about your chair setups, and any Eureka moments you've had or techniques to share. Lots of solo techniques available on line and in print but I've yet to see no sidecar technique vids or found any technique advise, how about we share our positive and negative experiences on this forum. Setup: What do you find is the best set up for the chair suspension? on a solo the front and rear should compress equally when you push down on the pegs whats ideal for chair? We have only 10-15 chairs that's regularly compete in Aus and their suspension are set up from super soft to super hard there is defiantly no one size fits all. Eureka Moments: Having the passenger squat over the rear wheel and pop a small wheelie with or without the sidecar brake......instant 90 deg turn to the left :). Keeping the steering strait up a slow left hill climb and using the sidecar brake to veer left whilst the rider concentrates on traction and throttle control.

rabie Posted April 12, 2019 Report Share Posted April 12, 2019 why knoblies on the chair wheel? - all the ones over here just have a road (smooth?) tyre intresting chair design, esecailly the handle!!! i'm just a beginer sidecar guy so i'm not one to proclaim to know the answer one of the things that have changed over here since the 60's is chair design allows the passanger to be more mobile my chair is from late 90's / early 2000's and had a footpeg on the rear wheel spindle for the passanger, that idea is now old hat and most have moved (and i've had metal work done to enable it) to have a platform further back, allowing the passanger to be further back changing the centre of gravity. we've also had a handle over the rear mudgaurd to give the passanger something to hold onto Quote Link to comment Share on other sites More sharing options...
austini Posted April 13, 2019 Author Report Share Posted April 13, 2019 Rabie, Aussie chair designs are different, fully enclosed floor pan, little space between the chair and bike etc: lots of different people building different chairs that comply with our rules so lots of diverse designs. Some have footpegs over the rear spindle our chair has the floor pan further to the rear to achieve the aim however the passengers weight is not on the rear wheel just the chair. One chair used to articulated so the rider could set the chair angle on the move and ride more like a solo?? We still ride nonstop so we do hop more this is mainly due to our sections being designed around the solo sections which are tighter. 1 Quote Link to comment Share on other sites More sharing options...
nigel dabster Posted April 14, 2019 Report Share Posted April 14, 2019 You might do well to connect with Barry Watson from Richmond mc hes on faceboos, knows his stuff i believe. Quote Link to comment Share on other sites More sharing options...
austini Posted April 24, 2019 Author Report Share Posted April 24, 2019 So no words of wisdom from our sidecar fraternity, I would of thought any advise to assist and newbies or perspective newbies might have been a useful. I know when we started the first few months was defiantly a period when wondered what we had done. so if anyone out there know of any training sources please pass them on.

p@ul250 Posted April 30, 2019 Report Share Posted April 30, 2019 On 4/28/2019 at 9:09 PM, rabie said: there are pleanty of them around over here, many gave me advice on how to modify my outdated outfit, they just don't seam to be forthcoming via this method It's because we spend our time out riding them. As pointed out Australian chairs are totally different to what we use over here in the UK. so what works for us here may be totally wrong for others. That said, here is what is the normal set up here in the UK. Track of outfit:34.5" (this is the minimum allowed under ACU rules). sidecar wheel leading rear wheel by between 9.5" & 10.5" and toed in by 1.5" over the wheel base of the bike. Bikes rear shock fitted with a spring of around 900 to 1000 lbs per inch and sidecar shock (with 2" travel) with a 130 or 150 lbs spring depending on passenger size. I like to use the optional heavy duty spring in my front forks and I also use 10 w fork oil. As for gearing the bike down, I use a rear sprocket that is a couple of teeth bigger than stock. That's about as far as I'll take it today, but if people have specific questions they are welcome to contact me. 1 Quote Link to comment Share on other sites More sharing options...
Bricole 63 Posted July 30, 2019 Report Share Posted July 30, 2019 Hello Mon side car est particulier en plusieurs points.Je dois avouer que je l'ai construit pour le plaisir de la construction avant tout,le pilotage n'est pas mon "truc".Deja que je ne fais pas de zones en solo,ce n'est pas en side que je vais risquer de casser du materiel et de me faire mal. Je suis parti d'une partie cycle de Honda RTL 1985 ou 86{freins a tambours}sur laquelle j'ai mis une fourche avant Marzocchi de diametre 40mm pour resister aux efforts lateraux {pour la durete j'ai rajoute un ressort de 125 TLR enfile dans le ressort Marzocchi surprise,ça marche bien.Je ne connais pas l'origine de cette fourche,l'ayant achetee sur E bay.Un ami m'a donne des roues avec frein a disque provenant d'une Montesa 314.Deux etriers de frein AJP 4 pistons ,un disque arriere maison{usine dans un morceau d'Hardox ,}Sur la roue du panier{origine inconnue,probablement 50cc Suzuki}j'ai adapte un disque de Fantic avec deux etriers de frein China,un qui travaille avec le frein arriere moto et l'autre avec un maitre cylindre a disposition du passager pour faire comme les chiens qui se courent apres la queue. Le side est un chassis d'occasion qui avait ete attele sur un Fantic.il y a une dizaine d'annees. Je lui ai supprime le nez en polyester qui datait l'engin annees 80 pour lui faire un nez en tubes et tolerie alu.Dans le nez,j'ai mis le radiateur d'huile du moteur. Pour le moteur,c'est une fabrication maison.Je suis parti de carters 125 TLR pour la boite 5 vitesses mieux etagee que la boite 6 des 200TLR.Apres la pose d'inserts acier a la base des goujons de cylindre{l'insert arriere gauche desaxe de 1mm vers la gauche et de 1mm vers l'arriere,pour une meilleure emprise dans la fonderie et taraude a l'entraxe d'origine.Ensuite,pour que l'alesage cylindre passe entre les goujons d'origine{a cause de la culasse}j'ai decalle l'axe du cylindre de 1,2mm vers l'arriere et de 1mm vers la gauche de l'axe d'origine.Alesage du carter a 76mm pour passer le fut du gros cylindre. Le cylindre est pris dans une fonderie de "Kit 220 cc pour ATC 200 China realese a 76mm dans la fonderie.{l'alesage tombe dans le puits du goujon arriere droit mais tant pis pour les deformations thermiques.En partant d'une chemise de Citroen AX reusinee a 76mm exterieure que j'emmanche dans la fonderie ,j'alese le cylindre a 72mm d'alesage pour mettre un piston de 72mm china {de CB 250 china,a 17 euro piece,on ne se prive pas} Pour aller avec ce piston qui a un axe de 17mm je monte une bielle de Bajaj Pulsar 180 qui a le meme maneton que le Honda}Cet ensemble est monte dans des masses de vilebrequin de Honda 230 CRF qui donnent 66mm de course soit 1 mm de plus que la RTL Il faut reprendre l'usinage de la masse gauche en diametre .Faire une reduction epaulee a 104mm de diametre {celui de la 125 TLR} sur une partie de l'epaisseur pour passer vers le pignon de boite a vitesses qui toucherait. Ensuite il faut reprendre la queue gauche car la TLR n'a pas de demarreur electrique{faire une copie de la queue de 200 TLR pour mettre un volant moteur de 200 TLR}. Pour le circuit de radiateur d'huile j'ai pris tout le debit de pompe a huile pour l'envoyer au radiateur. Le retour passe par un bossage que j'ai fait souder derriere le cylindre sur le carter central et qui debouche dans le circuit d'huile d'origine . Le piquage de pression en reperçant le conduit de sortie pompe a huile {qui debouche sous le bouchon d'usinage a l'avant du carter }taraude a 10mm au pas de 1,00 pour visser le raccord de depart au radiateur.Sur le raccord,j'ajoute un piquage de pression pour mettre un flexible de graissage de l'arbre a cames fait avec de la durite de freins de VTT,et le diametre suffit. La culasse est une de XLR pour les grosses soupapes et les gros conduits dans la fonderie recreusee comme celle de RTL avec les epaulements autour des sieges de soupapes pour ne pas les dechausser.Je ne me souviens plus du volume de chambre que j'ai mis mais pour osciller vers un taux de compression de 8,il a fallu rehausser le cylindre de 4mm pour avoir du volume mort en haut.{faire le calcul avant l'usinage de la mise a longueur de la fonderie,ce qui evite une cale de hauteur disgratieuse}.Un decompresseur manuel fait l'affaire.Les goujons de cylindre plus longs sont tailles dans des grandes vis Allen.Pour supporter les deux beaux bebes qui sont sur l'engin,j'ai monte l'embrayage avec 6 disques garnis et 5 lisses.L'embrayage est le point faible du montage.Je suis en train de me casser la tete avec un montage a 8 disques garnis de grand diametre a base de noix de NS 400 R ,de cloche maison ,mais le carter d'embrayage en mecano soudure necessaire me cause des soucis de conception et realisation{je n'ai pas le poids du HRC pour faire un carter comme la 270 STW.}Avant d'attaquer l'usinage du cylindre,j'ai fait faire et souder des grosses ailettes de cylindre par un ami{celui qui a fait la Terrot 500 trial des 2 jours d'Ecosse }Je les ai fait faire avant l'usinage pour que le l'insert fonte d'origine tienne l'ensemble et limite les tortions a la soudure. Mon engin n'est pas le plus beau,ni le plus performant,mais il me va et a mon age je ne compte pas faire 100000Km avec surtout qu'en france,pour avoir des papiers c'est une autre paire de manches on est en france.
