-6 people
-Hilux 2.8D DC 2003 (diesel:tank 65l+40l in carnisters)
-Jeep Unlimited 3.6 automatic LWB, larger wheels, well prepared (petrol: tank 70l+70l in carnisters).
-Honda XR650R tank 10l + 55l in carnisters on hilux.
Observations:
-no problems with regard to security at all
-it was harder to ride/ drive than in the late November (warmer-looser sand in April).
-1day was very hot- above 30*C, the rest were pleasant, windy (20-27*C). We even encountered a small sand storm but we were able to move on. It was beautiful, but very easy to get lost.
- 1first ended in the late afternoon with jammed throttle in XR. At first glance I thought it was a broken gas cable. After close inspection it turned out that there was some sand in the carburettor that had caused all the problems. My air filter must have weighted at least half a kilo. It was all clogged with sand.
The good thing about the 650r is that it is very easy to take out carburettor if needed. I cleaned everything, put a new air filter and slightly smaller main jet to get rid of starting problems. I used a lot of universal bearing grease to seal the air filter and the cover. It all worked perfectly and I had not any sand in airbox till the end of the trip. After changing the main jet I was able to start the engine while sitting on the seat.
I recon that if you ride smart: take the line of the least resistence, choose firm sand, use momentum and avoid excessive wheelspin your air filter will not clog so fast. But if you like to challenge each dune, one after another for the whole day it would be sensible to change airfilter in the lunchbreak.
-air pressure in XR: front 0,75Bar Rear 0,55Bar (S12XC Michelin tyres),
in Hilux: 1,0Bar; in Jeep 1-1,5Bar
-fuel consumption: XR used 40l for 400km including one major cleaning of the carburettor and the airbox. If you count 10l/100km it should be enought.
Both cars used all of their fuel in carnisters. Jeep used almost everything... For loaded Hilux it was not more than 25l/100km and for the Jeep it Was almost 35l/100km.
- for Tunisian desert SWB with good approach and deperture angles is best
-for the whole group we had 168l of drinking water in bottles + 40l for washing
-after the sand storm the central locking and power windows in Jeep refused to work, the local electrician in Douz flushed the main module with petrol and everything started to work again
-I wish someday I could ride from Lac Erreched to N3 in Algeria, that would be a chellange
