D16rr 15,000 Mile Service

Discussion in 'D16 Desmosedici RR' started by Dave, Sep 30, 2015.

  1. It really does take a very special tech to work on a D16.

    Very impressive, what's the final bill, if you don't mind that is !
     
  2. Free, in with the price when purchased.
     
  3. Yeah I read that [emoji106] just wondered if any additional work was needed that was not covered by the voucher.
     
  4. After viewing this set of pics I need to go and take a cold shower. Or something.
     
  5. Thanks for posting the pics. What a machine.
     
  6. I paid for some parts and some labour to have the engine apart while it was out and the carbon cleaned off (not part of the 15k service but I thought it worth doing). I'll dig the invoice out and post it here.

  7. Thanks for posting the pics. Something you'd not normally see

  8. Wow that's what you call a service!! Impressive
     
  9. At £40k or whatever they were the D16RR was actually quite good value taking into account residuals, service cost etc.

  10. Just seen this thread (I've been having work and life in general getting in the way of most things fun) and WOW! That's some serious service - on a serious motorcycle!
     
  11. I feel dazed & confused :)
     
  12. Wow, you definitely need to know what you are doing when working on that.
     
  13. I’ve just heard from another D166rr owner that his bike is at JHP and needs new valves. It was mis-firing and 50% down on compression. I’m not sure what mileage it has done but likely a lot less that 15K.

    New valves - over £500 each.
    New gaskets - £250 each.
    Total cost excluding labour - over £7.5K !!!

  14. Ive never seen valves do that before!
     
  15. Carbon coke build-up is a known problem with these bikes, and burnt valves like these in some cases as well. Mine needed a clean at 3 years/15,000 miles in the service described earlier in this thread …. but thankfully nothing more.

  16. Any ideas as to what causes carbon coke buildup? I'd be curious to know the reasons.
     
  17. This reminded me of the Bikeworld Desmo... I wonder what happened to that bike, I think there must be a story behind that bike, maybe it was found to be stolen or something?

  18. Incomplete fuel combustion.

    Those of us that grew-up on 2-strokes know the problem very well (expansion chamber off, plug one end and fill with caustic soda) but it can also occur in 4-strokes.

    Good explanation here https://axi-international.com/carbon-deposits-what-is-carbon-buildup-and-how-to-prevent-it/

    Low-speed stop-start riding seems to be the biggest contributor. My D16rr was used mainly on track and open-road touring and had only a little carbon build-up after 3 years / 15,000 miles but nothing like this bike and could be sorted with a clean.

  20. I was watching a TT programme the other night and Tony Scott the engine tuner was on it saying that engines need to be revved and used hard , that's what they were designed for. Worst thing for an engine is short trips and not giving it the beans.
