Actual Engine Compression Test (TBR7, etc) specs?
 

Sorry if this was already covered in an old post but can't find it via searching, so posting a new thread.


I have a TBR7, noticed more than what I should expect gases coming out of the crank case vent. So figured I would do a compression test, but now that I have results I don't actually have specs to compare them too.



I know the basics numbers we all share when doing any compression tests, but wondering if there were actual specs for the 229cc engine(TBR7, Hawk 250, etc.)?


Thanks!!!!

I'm not aware any as yet. Being that these motors are clones of the Japanese motor, you may be able to find the Japanese spec and use it as a rough reference.

This may provide some guidance.
