Hi All Is it normal when you remove the oil filler cap for the rev’s to increase on a 1275s motor? How do you tell whether you have a vented or non vented cap Thanks |

Q1 Yes, the extra air into the manifold increases rpm. Q2 The vented cap has an air intake below the handgrip. Either cap type works. I have run one of each on my 1360 and 1412 stroker. |
