    Do you ever notice how big some parts tend to stay even with displacements that small? Cam for instance. The carbs are as big as the engine top end is. And charging parts.

    'Left paddle shifter declutches and shifts only the left transmission.
    Right paddle shifter declutches and shifts only the right transmission.'

    That may well give trouble. Both actions of...

    Not electronic YET, your engine coupling idea would force you coming up with at least one engine ignition and timing unit since you likely lose it on one crank end. The electric servos will have at...

    If you knew the numbers of things I have thought up to never be built or made, the vast majority of them worked, but are they practical, the answer being no puts the idea out of my head. It working...

    Yes.

    The turns MUST have excellent grounds to cycle properly. Front bulbs need to be IIRC 1157 and back 1134? Or 1034, been while.

    The flasher may use only 2 leads, one green ground is...

    Maybe. The beeper is simply unplugged to stop it and what I did on my same year same circuit 550. The turns must have enough load to flash or they won't, like if someone has used LED bulbs. The...

    LOL, this one can't go there, it makes too much sense. He has the trickitis really bad.

    'Most of the driving would be in matching gears.'

    I have to ask why after so much argument over having the 'half' gears.

    You're already doing what I predicted you would and before it's even...

    If the top triple contacts the locknut you do NOT need further, it serves the same function when the back nut gets tightened. Bikes have used that method as well for many years.

    There is no points, all electronic, leave it alone. Replacing the rotor may just get you another bad one, common. Run the one you have if it's working.
  12. Actually I'm somewhat wrong there, chordal action...

    Actually I'm somewhat wrong there, chordal action is reserved for chain drive not gear to gear. Gear to gear has close to the same issue with velocity ratio variation.

    Chordal issue comes from...
  13. Another thing you haven't considered is chordal...

    Another thing you haven't considered is chordal wear based on using the spiders so much as power splitters. Spiders have very wide teeth and the chordal effects go way up with them. Not a problem...

    I understand that you think the difference in drive speeds is auto-evened out with the center gear adjusting for the difference in the two side speeds. It may not blow up instantly but at the least...

    'This differential is not like a two wheel rear end with one ring gear.'

    WRONG, it is EXACTLY the same thing.

    '...the rear wheel would take the place of the drive shaft...'

    Incorrect, they...

    Dude, you are still missing that you have a standard differential there, I don't care how much you say no. And misusing the term sun gear too there is NO sun gear anywhere in a spider gear set, only...

    What brand of 4-1? I ask because a lot of them are eye candy only and do not work that well and if well baffled to be pretty quiet. A few headers can flow better and help the engine enough to need to...

    Since most weight is on the front there then that would lower the ability of the weight alone possibly empowering the diff to turn one engine backwards but does not get rid of it completely. And you...

    No, but valve adjustment is called for as nobody ever did them. It then lowers the compression. The valves tend to close up to no compression. The engine can be run until compression drops to 120 ish...

    The motors are identical. Any slight carb changes are due to exhaust system differences. If still using the F type 4-2 exhaust they will work perfectly and even without if you change maybe a couple...

    'There would never be a case where one side is held stationary...'

    Not possible, the vehicle weight can do it through the center of your diff. Then the power engine overrules the weak one. Say at...

    I strongly feel there is no refining for where you want to go, only whopping more complication. When you refine you trim back not add more. You obviously have dealt with such things only on paper....

    Get/use an OEM airbox, they run better than with filters like that.

    Compression test to see how bad the valves are, nobody ever sets them and why the engines are not running when you get them....

    Lucky you with no ethanol in fuel, I'd kill to get some. Do they even use any ethanol in the fuel there at all? If so, the stuff may be leaching into the fuel lines for non if like here. News reports...
