Let me start by saying I have not posted much on here so if this is the wrong place for this I apologize. I just had my whole top end rebuilt. 479 cylinder works big bore kit with vertex piston. Port/polish head, valve seats re cut SS KW valves and springs kit, HRC cam, Dasa exhaust and uni air filter no lid. Started fine when I got it back with 93 pump gas. I drained it and put in VP T4 for a race and had a hard time starting it on a cold start. I have to kick it quite a few times. Any ideas. Idles fine and good throttle response. It’s an 04.
