clear timing plug

Hello,

My friend own a Sportster 1200 and wants to check the timing with a strobe.
We do not have a clear timing plug and don't find one in our town, Arad (Romania).
Could you please tell me if it is possible to check the timing w/o using the clear timing plug ? Just remove the OEM plug and let the hole open, or put a glass window in front of the hole...

Thank you in advance
Marcel

I prefer to static time. With Ultima style and points you can set the timing without the motor running.
Another option on the Shovelhead is putting a scratch in the primary on the rotor where the piston is tdc.

You can do it but it's messy. Bike has to be at operating temperature and running at 2500RPM.
The key is to have an adjustable timing light.
I did mine like hoginedgewood suggested. Through the inspection cover.
