Hello everyone, I'm a new proud owner of a 44k km 5th gen VFR 800 FI I have above average mechanics skills so i started to investigate / learn how to remove the fairings. Indeed i replaced a lot of screws, mounted a PC Fan on the RRectifier and small stuff there and there Then i came across green coolant that the previous owner had no knowledge about it (how old it was or how many km it had) I observed that the VFR runs a little hot (read about this here on the forum) and so i started to investigate how can i clean any deposits inside the coolant system. Some one posted how to Citric Acid Flush the coolant system but as far as i know and investigated, citric acid attacks aluminium... So i wanted to ask about this... Has any one tried this Citric Acid Radiators flush ? I want to remove any rust, mineral deposits, and miscellaneous crud that the system may have for an 19 years old bike and add BelRay Moto Chill coolant or Motorex M3.0 (these options are available for me) Thank you in advance !
