I have been using this cylinder for 1000 km , it is not as good as an athena. You need to add more base or head gaskets as the psiton heads the head with the supplied gaskets. Its is better than a standard 43mm iron kit but needs the conditions to be good to pull 4th gear properly. Save your money and buy an athena.
I am English,sorry no Danish and apologies in advance for muddled Google translations.
yes yes i am absolutly enig with allspeed - i have a athena 43mm and it is more tight between piston and cylinder, so there is fantastic hi pressure = good power at low rpm... it is allso a long live cylinder - nc is just a bad kopi off athena without performance and it is not a nicasil as athena are... athena is a expensive cylinderkit, i pay 1500 dkk for it ( it`s 200 euro ) peaple who just say`s a alu cylinder is some fuck, have never tryed a athena... many peaple on this fs1 forum say`s a alu cylinder have no power under 10000 rpm becauce off the big exhaust port, and that`s not korrekt - it`s becauce a athena cylinder need a expantion exhaust... normaly exhaust is bad for big ports... can you explain it too them ??? hilsen claus olieklud...
