1. Why are there vendors listing the new engines as temporarily unavailable for the last few weeks?
2. What can I expect to pay for a piston/sleeve for the S5 L2G?
3. For as much as people like these engines, I know they cannot be perfect. What are some of the common issues I should expect if I get an S5 next season? I can't find any negative comments about RB other than isolated failures that were probably due to the user.
