Into town for some fuel, it was chaos with the roadworks
Jack's hydraulic clutch had failed on the KTM 990. All the oil had leaked out of the reservoir, through the master cyl. seal, this was not good news with 7,000 km to go. He went to hunt down some vegetable oil to see if we could get it working again
The local kids were very confused by us waiting there
10 RMB and they were gone
Jack had a little bit of clutch control so we pressed on
Yaks
Back up at a pass, Jack's clutch resvr. was leaking again, he had no way to disengage the clutch now
Rob inspected it inside to see if there was any obvious seal damage, we couldnt see anything
We manage to bump start Jack with no clutch, he rode in 3rd gear all the way then. Getting close to Ya Jiang now, looks like Jack will make it
Jack made it as far as town, he was then pushed the last bit to the hotel.
After dinner, more vegetable oil was added & the clutch started working again - not leaking, all very strange.
What we think happened was at 4,600 meters the different air pressure, forced the hydraulic fluid to blow passed the seal. Think of a bag of potato chips you take up high and how it looks like its about to burst, we think the same thing happened to Jacks hydraulic clutch system. Once it had been opened and the pressure equalized, the seals could then cope with the climatic pressure again. It's now working fine. All very unusual, would never have thought that would happen.
All fixed and time for a good nights sleep in Ya Jiang
