    So this weekend i got the service done, new oil/filter, new plugs. Also managed to do the twin disc setup.

    Im gonna do the rec/reg tests today.
    Just wondering what people are measuring @ idle / @ 5000rpm.

    I've also got another couple of stators and regs i can get my hands on (spare parts motors/bikes) but just wondering whats available aftermarket stator wise thats possibly upgraded ???

    So i tested the stator, 70v ac across all terminals @ 5000rpm. Thats good :)
    Tested the reg output, avg under 14, around the 13.2v @ 5000rpm.
    I also noticed the 2 pin 12v DC plug on the bike side was melted, so i replaced that, also replaced the reg with another one i had.
    Bam presto, 13.8-14.0v charge at idle, 14.2/14.4v at 5k rpm.

    I dont think that was my issue tho (it was another issue but not the cause of hard start), I also tested the battery, leaving it for 24hrs, voltage checked out 12.7v so thats ok. During crank dropped to 11.6v, so thats ok also.

    I did notice when i got it started, it smelt rich. I've leaned out the needles and set the idle mix screws, but i think i might have some air passages in my carbs blocked. Anyway i got another set of across carbs i'll build up and changeover.

    Here's the charge plug on the bike, or what was left of it before repair.

    Here is the twin disc setup. Uses all across parts. The only non across part is the master which is still a suzuki 5/8 unit.
    Whilst i was at it, i put new seals in the forks, cleaned up the inner tubes and used synthetic 10w fork oil.
    Keep in mind the parts used are from used bikes, so it was more if its possible/how it feels before i spend money and get new discs etc...

    Pretty much.
    Used my original RH fork/brake setup, used the LH fork/brake setup from donor inc wheel spacer and axle, bolted right on.
    I did trim the backside of the wheel spacer but that was about it. When im not feeling lazy i'll make up a new spacer for it.
    Used a double banjo bolt in the master and done.

    just checked the donor's bike front wheel, that isnt pre drilled for the disc, so you would have to drill and tap it or use rh disc front wheel that is pre drilled.

    edit : another interesting thing is early across/rh disc models, have the same part number as gs500 front wheels, not sure if this is another option but its possible.
    the last 3 digits of the part number are different but thats just paint color identifier

    I just sync'd up the carbies, seems to idle better and smoother. Time will tell if it helps.
    They were are fair bit out LH vs RH sides.

    So far, i haven't had an issue starting the bike. It has been a bit warmer this week, so will wait and see.
    I still plan to rebuild my spare set of carbs for it. Just waiting on parts to come through.

    Just be aware that the charging system won't be too happy about LED globes... less current draw.

    If it is a standard reg/rec, it will be shunting unused current to earth and it will get mighty hot.

    It may not affect the Reg/Rec immediately.. check the cables from it and the connector.. just to be safe..
    Apart from that the lights look good.. care to share which one you used and how easy / hard it was to fit up etc.

    Yeah i did check all the connectors and cables, no issues so far. Rec/Reg wasnt even warm.

    This is the kit i used, super easy and simple H4 setup, Plug and play and i just cable tied the little box to the flasher can. No mods needed. Bonus is in the kit i got a spare H4 if something goes on the setup.

    Any troubles removing the reg from its frame , the across screws almost always strip when undoing them

    Cool mod. I checked my 3 x Across/Bandit front rims & they all have holes in both sides!
