I've recently bought myself a 93' Honda CB400. This bike is in fantastic condition but is let down by a few parts that are less than fantastic. I like my bikes to look like new. My question is, where in Chiangmai can I buy spare parts for this bike?

Your best bet is Red Baron in Bangkok. 02-729-4131. Here in Chiang Mai check with Khun Sa. His shop is on Mahidol Rd. on the west side of the street just before the post office. The CB400 is such a common bike in Thailand there's bound to be clean used spares around somewhere that fit your needs.
