If you are in Bangkok the place to go on a Saturday nite, are the markets on
Lat Phrao
Take MRT to Lat Phrao station, follow signs for Park And Ride, when you come out market across road.
Market starts about 7pm, have for sale, Honda 70's, 90's, bikes like in fotos, heaps and heaps of vintage indacators, head lights bike parts etc, even a new speedo for lambretta scooter, ( my interest)
need a couple of hours there to check out the stalls
was there last Saturday, and good to see the immaculately restored VW Kombi vans the owners wer bringing there stuff in.
More or less guaranteed to get any bits you want for your bike, they also had a cuple of bikes like yours for sale there
