So I just bought this bike to flip and I am trying to get the info together to list it and can't quite figure this out. The bike is titled as a 92 Special Construction using a Paughco S147 frame. The crankcase is numbered EBLF900###. I was told the bottom end was Harley but I can't get that serial to cross reference. Secondly, look at the pics. Do you think someone has installed plugs in the compression release ports? Ever seen that? I can tell it has high compression because of how it starts and how it kicks. BTW, this bike has been running strong for over 20 years.

The compression release hole would be on the top of the heads, those are just dual plug revtech heads, I cant speak for the rest of the motor.

I have a bike in the shop with the same setup, like I said to my knowledge those ports are intended for plugs.

Did some more research. CC catalog has automatic compression release valves that can be used in the second plug port so I guess they are optional.

Hope ya never need any motor parts for it.....
If so.... They will be on a slow boat from So. Korea.... Yup, that's where they are being made... :eek:

That cc number may be a state issued VIN number that was stamped in the case (maybe a blank replacement case originally?) as part of the process to get that SC titled

But in this case, if you have a SC bike, who cares if its an hd case or not? I say that only because it isnt titled as a HD, its titled as a SC. As long as the numbers on your title match whats on the bike, you are ok.

The number is not stamped it's actually cast in, "embossed" or raised, instead of stamped. It doesn't follow the Harley scheme. At first I thought it was a FXRS case because of the EB and then the L being 1340 but the F messes up the Harley scheme. I don't know if it is a full revtech motor or just revtech jugs and heads. The guy I bought it from said the case was Harley. Revtech motors have a bad reputation but this one has lasted over 20 years. I want to flip it but want to add some cred to it if it is not a full revtech motor.
