Good Mechanic need to fix modified Yamaha Nouvo

[Bealo]

Firstly let me say what a great forum this is. I have been reading threads in the back ground learning whats what from the experienced group on here. Thank you for you help/advise.

 

I have a Yamaha Nouvo which i've had the engine made bigger with a 158cc Yamaha big engine from a scooter shop on Soi Bukhao. 

 

Unfortunately the bike is slower than when it went in for the new engine and it keeps eating batteries.

 

I am losing my patience with the owner and have come to the conclusion that i need to find a decent mechanic who can look after my scooter for me and set up the carb and sort out the battery charging issue.

 

Can anyone recommend a good tuning shop/mechanic who knows what there doing with modified Scooters.

 

Thanks in advance.
