    i may have to switch over to it. So where would a person find a 68µF 25V electrolytic capacitor?

    The internet!

    Is radio shack still open? they would probably have some. otherwise, amazon. http://www.amazon.com/pieces-Electro.../dp/B00M2ES2F2 these are 35v, but thats fine, its just a rated voltage. you could run it through a 250v cap if you wanted even.

    Personally, i feel like the Monkey father / Finbro / Franco of finbro, should go back to the drawing board, and use the US based grom ecu and put their programming on one of those to keep the stock auto enrichment. BUT because that is not the case a kit of something like this would be nicely included with the ecu and really its all of 5 bucks extra in parts. You could even go as far as not requiring any soldering by using a bigger DPDT switch that you could use blade connectors on so everything is just crimped together.

    Thanks for this info. Does the 31 mm TB finbro sells support the high idol valve?
    No idea, but i think the 31mm TB that finbro sells is simply a forza 300 TB, those stock do not have a high idle valve, but better they have an idle air control valve which actually does the job of the idle air screw and the high idle valve on our groms. That stated, this is a much more complicated piece of equipment and our ECU does not support this, so its blocked off on the "finbro" ones.

    Like the person above linked to any 68uF cap will work so long as its got some headroom above 12v (i would say 25v would be the lowest id go). That stated i got my 68uf cap out of an "assorted bag of capacitors" from radioshack.

    Did you install dual valve springs? I hear the Finbro ECM revs to 12,500 rpm

    Yup the revlimit on the finbro is 12500.... for the stock 125cc and stock exhaust its pointless to run past about 10k or so, so nope i have not put dual springs in.

    I just purchased all the parts to get this done, will hopefully do it this week after work one day. Still waiting on my exhaust so will be delayed in trying it out. fwiw, Radioshack only sells the 68µF cap in the mutli pack, can't buy them individually. We'll see if it's the same for my 8-hole injector/170 4v. The Koso 34mm TB I'm using has the high idle valve.

    I would also suggest to add some hotglue or epoxy around the switch solder joints for extra security in regards to vibration, especially on this bike.

    Definitely report back!!! The 68uf cap worked well with my pcx 150 injector, it might not be the same with the bigger 8 hole injector (though theoretically if its the same OHM rating the 68uf should do just fine) But worst case you go the variaty pack from radio shack and i think there is a 100uf cap in there.

    And yeah On my switch i captured every solder point with some heat shrink then encapsulated all the connections in a big piece of heat shrink. Vibration disconnections shouldn't be an issue!

    What size jumper wires is safe to connect these together? 18 AWG or 16AWG?

    18awg will be more than sufficient. Highest current draw is from the injector and thats all of maybe 1.5amps at absolute most.
