Question 1: 1982 CB900c Compression results. Motor tear down needed?
Answer: Results look normal for its age! Get it tuned up right and run it!


Question 2:1999 Yamaha WR400F low idle and bog issues

Answer: Check out some of Matt’s videos on accelerator pump tuning. Sounds like you just need some small subtle tuning to get it dialed in.
