Topic: seeking info on screw in compression guage adapters

[jonda500]

Hi just wondering where I might find an adapter that will convert my compression guage to the smaller spark plug size these bikes have?- sorry I'm fairly certain this has already been discussed somewhere but I can't find it, Thanks

Thanks Dave, I found the thread from fenders profile and explored the links - gee they want a lot of money for a simple adaptor! I wonder if I can just remove the guts of an old sparkplug and braize on a nut with the right thread for my guage...

Haha! I wish I was the expert. Trying to learn more. 

Plethora of gauge adapters in eBay. Make sure they come with o-rings and are from a reputable brand. I recommend Actron, formally known as "Sun Pro".

You may just snatch the CP7828. For $40, you get a lot on the dollar and the gauge is pretty decent. Plenty of adapters and a nice pouch for storage.

[dave500]

[dave500]

i believe my home made adaptors are as good as you can buy?just not as shiney?

I believe my 8 miles high is below sea level....compression gauges suck.  They only lead to to believe that you should tear apart perfectly good engine.
