    I think I am going to have to do something like that :shock:

    Now for the insane side of things :evil:

    Would it be possible to put a engine on both the bike and sidecar? As in 2 engines for more vroom vroom power to haul 2 people easy? This is of course only if needed... I am just wondering if it would be impossible to time the engines to work in unison to pull at once.

    yeah the neat thing about that sidecar is that it actually allows the bike to lean! I do have some compressed gas struts from my Audi. They hold the hood up would be enough I think to allow me to lean without crushing :)

    The struts may be dead that were for the car but they will restrict the movement allowed.

    i just put the link in to further the discussion.

    properly "tuned", i think the gas-charged strut is a good idea, sorta help keep you upright, absorb bike/sidecar vibration, and help control lean when needed 8)

    Yeah I was noticing on that sidecar that there was looked like tierod ends for a car. Anyway the lower ones I could replace one of those with the gas strut. Then above I could put one so they are opposing forces that create a stable non tugging setup?

    a brake lever that pulls two cables at once could be used to control the throttles of both engines. It would need some balancing in the length of the cables to get it right, though.

    I was thinking of using the stock accelerator and a cantilever yoke to allow both to be pulled at once. This would require some barrel rollers to make it smooth I think but it would work? Then I could just use a single cable for the clutch/throttle.

    What do you think?

    I like that link Augi,Bird did some nice work.It looks more like a sidehak for racing than a side car very cool. That gives me an Idea :shock:

    ^IMHO... No way, 2 cables and one handle is a must... if you try to use one cable for both I fear you will rob yourself of the ease of barrel adjustments for each cable... if you are trying to adjust 1 cable for 2 motors then every adjustment will have to be directly offset by an adjustment for the other... essentially you would be fine tuning from the very start of the project and forevermore, instead of just a bit at the end and a little every so often...

    Where would you mount that? The dual pull lever is good becuase you can route each cable individually to each engine, taking whatever path is most convenient.

    With that yoke you will have to find some place to mount it, and then continue to route the cables after that. I guess it could work. Seems harder though.

    I say this becuase from the cantilever yokes I see on google images, it seems hard to mount in any place other than for the brakes.

    old twins

    Joseph,The older Jap,and British twins had a throttle that pulls two cables at the same time.The bonus is they can be bought at almost any motorcycle shop,and they fit 7/8s bars like our bikes have. Then you just have to adjust the cables one to each motor.They also have a top adjustment at the throttle for cable sleaves.Hope this helps out alittle.I was planning on doing something like this with the two motors can you tell. :grin: :grin:

    Re: old twins

    Nice, I didn't know that. I think telling the OP that info would be more helpful than stating it to me by name. :grin:

    Yea I noticed that alittle late sorry about that Joe. :grin: I do like his idea for the clutch though.One cable for 2 clutch's thats got to be cool.Sorry about the mix up Rod

    No worries I read through it :)

    I will have to look into that and find out what can be done. I think if I do dual motors I may have to add like 20lbs to the sidecar by the wheel to keep traction when nobody is riding.

    Is this similar to what you were talking about?

    As well as this for the clutch.

    After seeing that dual-pull twist throttle, I think your best option would be to use that twisty one for the throttle, and the dual pull lever for the clutch. That would basically be the perfect setup for you. Only problem would be balancing these motors so they get the same throttle amount. you wouldn't want one going faster than the other....

    I would love to see this made.

    Thats exactly the same throttle I was talking about,But I didn't even know about that brake pull.That would work out great for the clutch's,and you could adjust each as you need to.

    Indeed it would be a bit difficult to get them to match that is my main question. This is only a plan if I have issues with having the extra weight. However I may just do it for fun :)

    I wonder if they would consider it 140cc or just 70cc motors on there :) given they are separate and do not allow it to go any faster :lol: .. they being the Law

    Retro thanks very much for the idea it should work wonderful :razz: and it seems that its not expensive Ebay has it for 20$

    No Problem thats why were here :grin: Thats were I saw them was in Ebay. 20 bucks is pretty cheap too. You'll probably have to order the pull lever though.I still like the other idea (one pull,one cable)working both clutches,but you wouldn't have as much adjustment.
