Hello Roelof,
Thanks for all your helpfull posts about engine porting timing and mods,I curently test the singh grooves.
About the engine it is AAC and the sleeve is exactly the same as the ABC(I can't post pics yet cause these are my first posts here.).
It is a Sirio based engine but I do not know which sirio conrod will have a direct fit.
As i can't find any Capricorn-Sirio Glow plug I need help on which brand plug should I use.
Thanks in advance Dsond.
