Carbtune II.

[Saul]

I have had mine for 20 years, used it for my BMW Airheads many times in the past (if you have owned one you will know how obsessive carb balancing can be with those bikes).    It's a great piece of kit that works well.  Anyway in the time I have had it the the pipes that came with it have aged to the extent that are no longer usable.  I tried softening them with heat but they are past use.  I looked at sourcing some new genuine Carbtune replacements and it is cheaper to buy a Chinky set of gauges with all the adaptors and pipes than buying 4 new pipes for my Carbtune.    I can bin the Chinky gauges  if I need to and still have all I need to use my Carbtune again.

Know exactly what you mean @Saul....my carb synchronizer's tubes are getting pretty stiff from age as well. Don't have much use for them anymore as my bikes now just have pedals... Going w/ the chinesium route makes much more sense...especially w/ the wallet.

They are just vacuum hoses.
