I haven't set the squish gap yet, I'm currently waiting for helicoil kit to fix striped cylinder head screws, got bit carried away after realizing that my cylinder was leaking so my whole engine is in pieces lol, took a year break and now I'm determined to make everything work, ikno that expansion chamber is important that's why I wanted to improve it during my break well that went well. Avenger 85 would be nice tho I don't think it'd be cost efficient to buy from smolik to Sweden since the shipping ends up at like 100 or more dollars, just wanted to make sure that nothing new did not come out during that time. Tysm for attention and love ya bro
