    Spence, do you have any idea how much lighter the titanium retainers are compared to stock?

    I have not measured myself, here is a copy paste post about weight. Back in the 215 4tec days but assume its similar

    "stock valve retainers 11 g
    rotax racing alu retainers 5.3 g
    titanium Retainer 4.2 g

    the rotax racing aluminum retainers are "hard-anodize" and general have no issues, but you should check every 25 h like Jerry says.

    problems with the RR aluminium retainer also depend on valve/CAM setup.
    the are running in the factory engine very well over 9000 RPM for 25h+

    the titanium valve retainer are a bit stronger and lighter,"

    Thank you for that info, Spence. Reading what you said, I would stick with Titanium.
