cylinderhead is from Tomos CTX. it is good, becouse it has almost excellent squish, but i still need to make some measurements

realy nice
I have some question
I wanna give my bt engine more compression
i have a Bt cilinder High pressure cilinderhead and another exhaust 18mm intake and dellorthe 19mm carburater
Ive heard that there are 2 holes in the carter where your crankshaft is
if i fill them it have more compression
Can you confirm that?
And is there any limiter in the exhaust i have a NTX exhaust something like on a CTX
II hope you will help me

you can fill those holes in crankshaft with cork... it have some effect, and if something happens, cork is soft and it cannot do any dammage
it wont lift your compression, but performances will be better.
the only thing you can do for better compression is lowering cilinderhead
ctx exhaust has limiter. inside is a longer tube, wich disable resonant effect... and it have metal grid allover the exhaust

well it depends on what fi of cilinder do you have...
if you want to know which mark... there are a lots of marks of pistons for tomos... i use vertex or meteor, könig is also very good
, i strongly reccomend that you do NOT use sukoki... it is very bad quality and toleranced for watercooled engines...
