    Dunno about that notion dude.
    With the weight of the chain and its velocity at even relatively slow speeds, I expect it'll just be a mess - you'd be better staying as you are at that stage.
    I...

    OK, so even if the lower support was gone, you still need to limit upwards travel, which means you need an additional element in any case and so the whole cycle reverts.

    Have you considered...

    Isolating the casing of the charger isn't going to fix anything is the charger isn't plugged in.

    ...I had a far longer post than this almost written but as I was finishing it something occurred to...

    In the case of this arrangement, an increase in L1 will have a disproportionate impact on the chain slack on account of the narrowing effect it has with respect to that window of travel in the...

    Stevo: that idler pully - is that just to take the chain over the top of the center stand support bracket?

    ...if so, is just cutting that out altogether an option?
    Can't imaging that chain...

    Agreed



    You're right!
    I had actually meant to encompass that into the formulaic result but I've not actually done that successfully in that first equation.
    Despite this, for L1 'much less...

    OK - now I see the problem.

    ...and even with the humour intended, the below indeed outlines the missing factor (the undesirable design feature if you like) which I wasn't seeing.

    As requested Ted (and in nice Crayola colours too ;) ).

    It all comes down to the ratio of the lengths and the manitude of the Cos scalar. As long as the L1 << L2 then you're never going to be too...

    Not sure I agree with this - the alignment of the swingarm pivot, drive sprocket and driven sprocket has a bearing certainly; assuming good alignment, for any reasonable measure of suspension travel,...

    Yup, that much I understand, and assuming an inline arrangement, there's no problem there - a mismatch in torque between the wheels simply amounts to front to rear drive bias which won't impact on...

    I don't expect that would work, you might be able to balance the torque response to throttle with the main drive wheel for one gear ratio on the main engine, but as soon as you'd change gear the two...

    Hmmm.. in theory I could see this working with the Hub motor on the sidecar wheel alright; but ideally (and perhaps necessarily) the motor itself would have to be an induction or doubly fed machine...

    The Agni's are great motors, but I wouldn't even consider using one in a hub config if you're after 100MPH and race spec performance.
    Suggest doing some reading up on 'unsprung mass' and its effect...

    Looking good - have you incorporated compression plates into that pack? Those pouch cells need some help in that regard if you're to avoid premature failure on account of delamination.

    Looks like you're basically dialling in what would otherwise be 'slip'... interesting way of doing things, not one I've seen before.

    As Frodus says, top balance is best even if for no other reason than you're at the top of the pack far more regularly than you're at the bottom which makes the whole lot far easier to monitor.

    Can't wait to see the look on any 2T kart pilots face when they mash the throttle on that thing! :D
