changing valve seals and guides

Absence of commercial self-promotion in the regular discussion forums applies equally to all members, regardless of status.

KZRider may not be used as a member's store-front. No hawking, pitching or peddling products or services of any kind is permissible except as expressly provided under the rule.

Simply put -- it is off-limits for any member to pitch their own sales and services in the discussion threads.

Good Fortune!
