Im getting these compression test results in PSI, all plugs removed and full throttle. 

 

 

150   155   150   155   COLD Engine

 

200   210   200   200   HOT Engine

 

 

do these look pretty good, i've had a search but cant find anything specific on 1098 engines. 

 

Thanks

I can't see anything to worry about. Check the compression, then check it with a couple of squirts of engine oil down the bores, using a a little oil can. Seem consistent though. :highfive:

As above, hot compression readings look sensible. Are you running about 10:1 CR?

 

Cold readings are however lower than I would have expected.
