it was a long story, firstly we guessed from carbu and fuel tank because of water leak to inside when sunk down at that time. then it all clean and the time drive back home engine stop again then back to garage once again and start to find root couse again and found electic current to distributor not smooth may from generator!
and it was right!!! seal at cover for transister room (at the back of generator)was old and let water leak inside all rust to every circuit....
I have no chance must go to a shop at woprajak he said it was new but when garage saw that he said it was rebuilt one not new he point out and it was true that shop charged me THB6500.
up to day I didn't drive him yet...let see what happen..I hope ne problem.
Next week I will be away from Thailand and after comeback I may call a TMVC BKK meeting some where...my idea is some place that we can drive as a small parade and park as a team...like suan loom night bazar or soi khao sarn.etc. what do you think..let me know...I will fly Sunday midnight
