well, I fear the rings may have crapped out on the CB550 cafe…I have an el-cheapo HF compression testor, but they don’t go down to small enough threads to fit the spark plug ports on the bike…If anyone has a quality compression testor that I could borrow, I’d be greatly appreciative. If it helps, I used my digi-micrometer and it says the diameter at the threads is 11.85mm. Thanks in advance. -Nick ---

yeah, I’ve seen some of the higher quality ones come with adapters that thread on the end to fit multiple plug-sizes so you can compression-check ANY internal combustion motor… ---
