150cc upgrade for SYM VS125 By rooman (Read 505 times)

[rooman]

I'm having trouble identifying my engine.
On the lower left side there is a number DM809893 and on the cylinder head I see H6T.
Chassis N° RFG HV12WY CS00 6144

I'l be looking for a trustworthy on-line vendor either for a standard 150cc sym cylinder & piston or a BBK.
It's a 4-valve (two 3-bolt covers) head. Engine-bolt center-to-center not yet measured.
HV12W variant...?

Any thoughts (not forgetting re-jetting).

center-to-center horizontal stud spacing 67.5mm,
center-to-center vertical stud spacing 45mm approx
inlet & exhaust valve covers 3-bolts
