I have an 08 525S that I built 3yrs ago, new HC piston, rings, valve job, 807cam… Recently It has been kinda hard to start when warm so I adjusted the valves. Were only out by .002”. Seemed to help but still wont bust off when warm. (run 93oct) Im cleaning the carb as we speak. It does not smoke at all. I’ve ran fuel fragrance a few times and wondered if this has caused any problems. Runs great when running but noticed losing power (got outrun by stock yzf450). Im ready to build top end if needed. Don’t know where to start. Thank you
