Engine Cuts One Pot When Reved

[fixitsan]

Do you know which cyl cuts?



 

I was going to ask the same question, but how do you know ?

 

I remember on my 850 when it dropped a cylinder, in order to work out which one it was I pulled the ignition lead off the plug while it was misfiring...on the basis that if it kept running I had identified the dropping cylinder. Easier to do in the garage than when riding it.

 

You could also put a hand over the carb throat, or, pull the low voltage 12V spade terminal from a coil.

 

If it happens from cold then the missing cylinder would have a cooler temperature exhaust downpipe

 

A fancy-pants Infra Red camera might help. Wish I had one of those !
