First, thanks for the encouragement to keep posting it helps. The absolutely worst part of going to Chiang Mai is that it's a hard place to leave, one day rolls into the next and before you know it another week has slipped by. So I resolved myself to get moving. I was reasonably happy with the way the bike was running but had some concerns about the air fuel mixture. The air box had been modified to accept the high flow K&N filter to give the FinBro more air and this was the only thing I couldn't put back to standard. I hunted high and low for jets to fit the old Keihin carb but couldn't find any the right size they were all 90 or over and I needed an 80 or 82. So without a clear picture of a route I decided to head towards Uttaradit and then to make a decision one way or the other about heading to Laos or not. Had a scary moment along the way when the motor seized momentarily from running lean and hot. I stopped to let it cool down, checked the oil level and then after adjusting the mixture screw to make it as rich as I could get it and still have it running I rode very slowly for the next few hours to Uttaradit. Looked around in vain for a cheap guesthouse before deciding I needed coffee to collect my thoughts and make a plan. Saw a sign for this place. <a href="http://s1160.photobucket.com/user/RDT953/media/Thailand%20Postie%20Bike%20Ride/R_WP_20140215_001.jpg.html" target="_blank"><img src="http://i1160.photobucket.com/albums/q493/RDT953/Thailand%20Postie%20Bike%20Ride/R_WP_20140215_001.jpg" border="0" alt=" photo R_WP_20140215_001.jpg"/></a> Ordered a coffee and got chatting to the owner who directed me to a nice new hotel close by where I secured a room for two nights at 500 baht a night. Also spoke to the coffee shop bloke about the motor problems and he took me to a workshop but still no luck finding a jet. The next day I did some tuning and test rides and by the spark plug colour I could see improvement but it's still running lean. With these problems I decided to kill the idea of heading to Laos and to just take a leisurely trip south to see the bits of Thailand I'd bypassed on my rushed trip north several weeks previous. The highlight of my stay here was this massive serve of mango and sticky rice for 20 baht. <a href="http://s1160.photobucket.com/user/RDT953/media/Thailand%20Postie%20Bike%20Ride/R_WP_20140215_005.jpg.html" target="_blank"><img src="http://i1160.photobucket.com/albums/q493/RDT953/Thailand%20Postie%20Bike%20Ride/R_WP_20140215_005.jpg" border="0" alt=" photo R_WP_20140215_005.jpg"/></a> Next day I took back roads south and made it to Nakhon Sawan. For most of the day I was riding in a smokey haze so no pictures. Arrived quiet late, tired and hungry so booked into an overpriced dump of a hotel right in the heart of the city. Had a shower and went looking for food. How lucky am I? I've arrived right at the time there's a food and produce fair on just around the corner from the hotel. <a href="http://s1160.photobucket.com/user/RDT953/media/Thailand%20Postie%20Bike%20Ride/R_WP_20140217_001.jpg.html" target="_blank"><img src="http://i1160.photobucket.com/albums/q493/RDT953/Thailand%20Postie%20Bike%20Ride/R_WP_20140217_001.jpg" border="0" alt=" photo R_WP_20140217_001.jpg"/></a> I'm worried about the motor and riding at 60 kph or less so I made the decision to leave early in the morning to give me more riding hours at lower speeds to achieve some distance.
