  1. Yes its a bit of a mystery  and thank you for the information regarding cams.

    The carbs are ultrasonic cleaned and rebuilt . the compression is within the spec's in the Suzuki manual.  The exhaust headers are made by Devil in France. though the rear can is unknown.

    I agree its a big drop from 112 down to 78

  2. Well the dyno has spoke and the result is arm wrenching 78bhp!! It ran well and quite cleanly but thats

    all she had on offer.

    I know someone mentioned ages ago the JDM bikes were restricted but has anyone any idea how.

    Is it all in the ECU or would the cams be altered profiles, etc,

    can this be sorted without spending another  fortune  on the 750 lump.

    The dash also has an annoying 'speed' light that comes on about 50 mph. thought it was the oil light first time

    and nearly soiled myself O.o

     

  3. Can anyone point me in the right direction for the colour codes used on a 1988 gsxr 750j.

    My local paint shop says the pearl white is no problem but need a code for the darker blue.

    the panels are too curved for his machine to take a reading,

    Slingshot 750s and 1100s are line bored the same so its fairly straight forward to build an 1100 into 750 cases. does it have a 6 speed gearbox?

    So does this mean an 1100 crank, block and pistons could be fitted to a 750 short stroke (J model) motor ?

    if so has anyone done this?

  5. Can anyone tell me what size the front master cylinder should be on a 89 slingshot 750.

    the one I have is marked 14. but have been told it should be 5/8 (15.9mm) struggling to get a firm

    lever that does not travel back to the bars. the calipers are 1200 bandit.

  6. I have a Jap domestic market 750 j and am trying to sort the light before mot and registration.

    As a jap market is Right side dipping (same as uk) should be ok, but the bike was registered in Belgium

    for a while so lights might be Left side dipping?? Have tried then against a flat wall and beam pattern seems flat with no breaks or kick up on

    either side.

    Is there any markings that would tell me what I have fitted before buying more.

  7. If you check the beginning part o the Chassis number it might help identify it. (though I obviously wouldn't post the whole thing on here!)

     

  8. Can anyone suggest what fork oil and quantities work best  on the 750 J front forks.

    I have stripped mine to change the seals, and managed to free off the seized top and bottom adjusters

    so could do with advice on basic settings. sometimes members find a different answer through experience

    than listed in the Haynes Manual.  Cheers.

  9. Is there a rear shock unit that is a known fit for the 88 j model . maybe from a later model(later K series) or even another make

    perhaps R1,R6, CBR,ZX6 etc. Looking for something that's been use before and proven.(might also be cheeper on Eblag).

    I know a new Nitron unit is about 450, but really on a budget with this one!

     

  10. Does anyone have a rear seat cowl for the 88/89 slingshot available for sale or rent/ loan.

    I am looking to take a mould from 1 for myself and then maybe offer a few up for sale at sensible money.

    I know they appear to be the proverbial rocking horse deposit, but someone must have a spare on a shelf somewhere.

    Cheers Nick.

  11. Well having been through the carb and some expense , New slides, guides, needles, jets and seals.

    I am now thinking the ECU may be faulty, engine starts but wont rev cleanly without misfire then dies just before coming back  to  tickover.

    Any idea's or recommended sources for ecu testing / exchanges.

     

  12. Hmm, possibly not the 'easy project' I thought, but they never are I guess. Just waiting for the carburettor refurb parts  to arrive then I'll give it a run,

    I don't mind a few mods but if it has different heads /cams pistons etc then  it a different game.The pink wire to the cdi reminds me of my 400 import gixer.

    Does anyone still do a rear solo seat converter for this model?

  13. Having just bought a project 750 j from this weekends Stafford show, (Dutch import to be registered). I have been informed that the chassis number shows this to be a Jap home market bike.

    I have also read on a few forums that this might be restricted to 77 hp. Anybody got any info on what restrictors might be fitted.

    Not ridden the bike yet, was hoping to re-live a bit of my youth that included 750 j and l models.
