  2. Looks a nice bike, enjoy!
     
  3. Welcome dude, we do like a SS
     
  4. Nice bike well done, ref the head studs even if they are the weaker ones they may never go, someone above suggested changing them as a precaution, personally I wouldn’t unless you’re going on a round the world trip or something, up to you though, one thing to look out for at oil change time is aluminium bits on the oil strainer gauze, the oil gallery plug on the crank is made of aluminium and can (very rarely) unscrew itself, it then makes contact internally and gradually gets skimmed away, this creates slivers of alloy usually finger nail clipping shaped, or sometimes ribbon like, if the plug comes out completely you lose oil pressure and it’s all a bit disastrous for the crank/bearings, so have a look at the strainer (big nut RH low down on the engine case, undo and pull out long plastic gauze strainer) when you change the oil as it’s the only early warning you’ll get, it’s very very rare though so don’t ride around thinking it’s likely to happen!, a few little metallic specs on the gauze and other small non metallic detritus is normal and nothing to worry about, in general these are very strong reliable engines so ride and enjoy!

  5. Thanks - but it will much cleaner once I have had it in bits! Needs a fairing off, deep clean / check over. Few bits to sort but not much. Will do the studs over winter.

  6. This is the best way to familiarise yourself with the new machine in the stable block,as i've just done this with my new bike.:upyeah:

  7. Great choice! Hope you have many happy miles together:cool:
    (think your bike bike may have worn half fairing at some time, has the correct rear fitting)
     
  8. Nice one mate, 944 kit, set 0f v2 cams and some 41's and your good to go :)

    Forgot, splash of yellow paint will finish it off.

  9. Agree - it has frame mounting points for CR model fairing. Import from Japan, only original paperwork is Japanese! Wonder if their bikes had fixings for both style of fairings?
     
  10. Bloody love a 900 ss! Welcome to the forums. +1 on the mods above also run it on the best fuel available. Cheap hi ethanol fuel causes havoc in the carbs if it's left for a long time as it forms varnish and clogs jets. A fuel additive before she is put away for the winter is always a good move.
    Enjoy the beast!

  11. Just a suggestion/question, is it possible to replace the studs 1 at a time? So as not to have to remove heads etc?
     
  12. The issue is getting them out, they can be in extremely tight, may need heated and to unscrew them you need a double nut at the end, which there is no room for with heads on. I doubt most of them would even get past the head either.
     
    • Thanks Thanks x 1
  13. One could try but the issue comes from limited access for a stud extractor.
    The head bolts on the cam drive side are very difficult to get to and I would imagine you couldn't get in with an extractor well enough to get sufficient purchase.

    For what it takes to take the heads off you may as well go down that line ad seals etc can be replaced at the sametime.

    These are my own thoughts, I may of course be wrong (usually am)

  14. And disturbing one head bolt will more than likely make the gasket leak :(
     
  15. I did say head studs will be on your shopping list, but I agree mith Mark9, don't go looking for trouble there, wait and see if it finds you.
    Mine was only a couple of years old and had done about 14000 miles when one failed, so they came out fairly easily.
    John Baines did them in a few hours, while I waited. (I had taken the motor out and took it down in my car).
     
  16. Got the bike back home yesterday afternoon, after a quick blat (nice!) back for an initial clean and disassembly to check it out :) There are a few problems to sort out - leaking clutch hose is number one. New one ordered from HEL.

    Had some evil stainless cleaning fluid I bought from Hein Gericke years ago, cleaned up the headers a bit.

    Couple of tiny cracks in headlight fairing to repair, plus crack around front mudguard mounting bolt. Also noticed rear tyre has perviously worn / sliced into rear hugger? Current 180 fitted has just enough clearance.


    Anybody recommend best method of cleaning ingrained brake dust from calipers?

  17. Was the 900 SS originally supplied with 170 section tyre? May be the hugger issue. Brake calipers come up a treat with Bilt Hamber stuff
     
  18. It was a 170 Harry, I believe a fair few have fitted 180’s though.
    PS to clean the callipers I start with a strong mix of household washing up liquid, agitate with a toothbrush (then put it back in wife’s toothbrush holder) then thoroughly rinse with water and dry off, then use Holts brake cleaner.
