    Size Chain Disk Goped esr

    Hello,

    I have a ESR750 and I want to change the chain transmission in a gear with belt . I'm looking for someone who has the dimensions of the '' old '' ESR measurements (see photo) .What i need is de size of the mounting holes and there places on the X and Y-axes .The bolt on the gear doens't want to come off sow i have to drill them out , but until then i want to make the gear with belt first (So i can still ride )

    Maybe someone has the drawing, or can measure it....

    I will post some pics how my goped looks like...

    Already did on my goped:

    * lifepo4 24ah (home build)
    * brake light

    One remote for:
    * remote control to start
    * remote control for light
    * remote control fot turbo or economy

    * City light Leds
    * Key if the remote doesn't work
    * Main switch if storage for a long time
    * 7 Amp charcher ( 3,5 hours full charge )
    * Anti slip upside deck
    * Front fender

    To Do :
    * change the chain for a belt
    * Rear brake kit

    Kind regards

    Cool ESR
    I dont have mine yet so i cant mesure it for you yet.
    Maybe you can find it on goped or ddm ?

    how did you wire the remote control for the power, turboband lights?

    Can you show the other power mods you did ?

    Already tried on Goped and ddm but no results....think i have to measure it by myself ...

    there is a lot of wiring about the gopeds on ddm or goped ( pinsettings ) i measured al the pins a long time ago from the switch to the controller....The remote i use is one from china with 4 Chanels

    Channel 1 = on / off
    Channel 2 = turbo / economy
    channel 3 = light on / off
    Channel 4 = free

    controller that i use http://www.amazon.com/Thunbird-Chann.../dp/B00BQ842DG this one is with momentary switch ( so only click and it goes off, like pulse ) but you also can order with no pulse

    Sow the switch on my steer for turbo / economy is removed, the red power button that is normal use for power the step on / off , is now in use to trompet my horn

    Also a switch with key, if the remote control doesn't work i can use a key, and a small switch if i don't use it for a long time...( cut all power off )

    The bolt hole circle on the rim is 2 9/16" I don't know about the smaller holes though.

    There was at least 3 different throttle designs in use over the years ( i do not remember the exact model years, but roughly: 2004-2005, 2005-2007/09 and then the current design since then).

    Measuring it by yourself icertainly best, otherwise we'd need to see a pic of your throttle setup to see which model it is and then hope someonje who did that measurement already chimes in with wisdom.
