  1. I should have taken a picture of my fix but didn’t.  I lapped the rotor on the taper and it smoothed out pretty good.  I didn’t do anything to replace the missing metal.  After the lapping I seated the rotor to the taper with Loctite 638 retaining compound and used red Loctite on the nut threads, she’s holding up so far.

  2. Soon to be started, cleaned carbs, fuel tank, petcock, lapped rotor to taper and secured with Loctite 638, new battery and cables, oil & filter & plugs.  This one sat it a garage dormant for eight years after the alternator rotor spun.

  3. Hello again,  can anyone give me the part number for the fuel adjustment screws on this ‘82 GS1000SZ ?   I looked on an online microfiche and they are not shown, presumably because they are “non-serviceable” plugged off pieces.  I have aluminum top cv carbs (US market), measured at 34mm.  Thanks 

  4. Talked to a friend of mine who has been in the mc repair and wrecking yard business for many years, his recommendation was after lapping the taper heat the rotor on a hot plate until it’s as hot as it will get then install to shaft and torque to spec.  This will allow the expanded rotor to cool and contract tightly to the crank taper.  Also he suggests making sure the ign timing is standard not advanced and maintaining a good proper battery that holds its charge 

  5. Recently acquired a non-running 1982 Katana in fair shape.  Removed the tank and carbs for cleaning, two stroke oiled the cylinders and installed a new battery.  After letting the cylinder oil set for a day I turned the motor over manually, so far so good.  Figured I try the starter and it free spun, no clatter and no crank rotation.  I remember back in the day that some of the 1000 Katanas would spin the alt. rotor on the end of the crank.  Pulled the cover and rotor off, it’s eaten up pretty bad.  I’m going to use lapping compound and get as much good contact area back as I can, then put Loctite retaining compound on the surfaces.  Any suggestions welcome.

  7. 3 hours ago, no class said:

    why 525 ? if your motor is stock.... drop the weight of your 630 chain and sprockets down to a 520 ..... it can handle the massive 125ish hp the efe puts out ;)

    Just looked up RK’s 520 ZXW chain, it’s rated 9,500 lbs tensile strength and 200hp.  I just didn’t realize a 520 would work on the 1150.  Seems that it would be fine.  

     

  8. I have found a lot of websites that do have countershaft sprockets for the GS1150 but none offering a 525.

    I went to the link you gave me, www.sportsbikeshop.co.uk and checked every 525 countershaft available for Suzuki’s, this is what’s listed:   DL1000, DL650, GSF650, GSR600’ GSR750, GSXR600, GSXR750, GSX650F, SV650.  Maybe one of these have the same output shaft splines as an 1100/1150 but they gave no specific fitment reference as such.                                

     

     

  9. I’m taking my 1150 clutch apart to check the condition of the plates as I have an intermittent slip problem.  There is a wire ring that holds the last metal plate in, I haven’t removed it yet, debating whether or not I should.  What’s up with that thing?

  10. APE has a 1327cc stock block big sleeve kit.  Their website has a drawing of the available sleeves and measurements.  If you are asking about factory Suzuki sleeves, I dunno 

     

  11. I have recently changed oil and filter, and I don’t know what oil was in it prior.  Now using  Valveoline mc, half 10/40 dino, and half 20/50 dino, not synthetic and not synth blend.

  12. 10,000 miles, but I have only had it for 1,500 miles and the clutch issue has just recently shown up.

     I am going to check the arm alignment and it’s free play, cable adjustment also.  I am most familiar with those clutches that use an adjustable “worm gear” that have you run the adj screw in and back out 1/4 turn.  So maybe I’m missing something on the GS setup.  Thanks for the responses
