    I had a collegue at work let me know she had a Suzuki Across under the house that wasnt running, I dropped over had a look and made her offer, suffice to say its in the garage and after an oil change, new battery and plugs she runs. Needs a few minior things for RWC, but wont take much. Its a 98 model wth 39000 on the clock and has a pipemasters exhaust on it.

    Needs mirrors, carby clean and the front disk sorted.


    thanks

    Chris

    The pipemasters exhaust has been removed a standard one fitted, carbs have been rebuilt and it runs like a top, its now registered and Im cruising around on it, nice bike.

    I fitted the 6sigma carby jet kit last week to my 1997 Across, ( cost $86 delivered from America). I was pretty peeved off when the kit arrived as it only consisted of 6 main jets and some nylon washers and spacers and 2 drill bits.  Suffice to say, I fitted the jets, adjuested the needles and the bike now has a heap more power, I still need to get my carbs balanced but it does go alot harder. 

    Im wondering if I should invest in the unrestricted igniter ? has anyone fitted one.

    Hey has anyone gone for one of these deresteicted CDI units?

    I'm keen to hear if they make any difference. What could actually be derestricted?

    Curious about that myself, mine seems restricted in no form at all, revs to about 17,500rpm in 1-3rd gear, and the cdi has no way of knowing what gear your in given theres no sensor. Doesnt seem speed limited either altho i do have the early model!

    Yeah, seems a bit 'snake-oil'... but then I've not tried revving mine out to anything past 13k in third.

    It's an easy replace job though I imagine - is that the CDI unit below the headlight on the Across?

    Brad, havent been apst 13k in 3rd, OMG, thats where the fun starts  :)

    Yes, the CDI is under the headlight, one day I will get one of these derestricted CDI's for my Across, it will be interesting to see if theree any noticable differences.

    Hey All
    Was chatting with a mechanic the other day and he assured all bikes are restricted in some way, therefore I guess it's a fair bet that fitting a new igniter will have some improved performance.
    My guess is this, the major manufacturers have to provide warranties with there bikes, hence the restrictions to minimise failure.
    Some one has to bite the bullet and get one of these igniters, if for no other reason than to put us out of our misery.
    Your thoughts                                            Phil

    I'm tempted, but I'm about to move into a house we've built and am paying the rent + mortgage double whammy at the moment - i.e. funds are thin on the ground.

    These units seem to be plentiful though - I'll be up for one in a couple of months.

    I so seriously doubt they would make a difference for a few reason -

    One the cbr250 ones already been dismissed as snake oil and they come from the same seller (look it up on the jdm cbr forum)

    Two, just ride the bike above 15k, there's no power at all there. An extra 500rpm if the unit even does allow that (doubt it) is beyond worthless. I don't think there's even a road long enough in the country to let you rev this bike out to the limiter in 6th let alone higher :p

    Third, No way would the Black top engines and the VVT versions use the same ignition curves.

    and lastly, a chinese CDI? >.>

    You'd be better off getting an aftermarket ignition controller and having it setup on the dyno. Doubt there'd be much to be had power wise regardless.

    I'm thinking you're right Desmo. I took the Across out on the weekend and wrang it's neck. It went to 15k no problem - after that I didn't see the point. i.e. it felt pretty much the same rom 13.5-ish upwards. Plus I kinda feel revs like that (often) is a good way to wreck an engine.

    Certainly found out where the power is on an Across though - after 11/12k.

    Hey I just put a 1990 igniter unit in my 1996 Across.

    It *seems* to have a few more herbs - and it's much happier revving out to 14-15K.

    Cool, well it stands to reason they would be a little different given the later models have variable valve timing on the inlet and i think they have different cams for more midrange. So if you have the later bike perhaps the ignition on the older ignitor is such that it gives it a bit more top end. Or something like that :p

    Would be interesting to see them back to back on the dyno.

    Not too related but some interesting info in the below link :0
