I bought a non running 2006 Midnight 1700 about a year and a half ago and been working on it a little bit at a time to get it up to where it needs to be. I have no idea how many total miles are on it. The speedo unit was hosed up and I bought a good used speedometer with about 20k miles -- that replacement item works great. The fuel pump was removed and that whole system was hands on setup to be pumpless by SkwearPeg. (he lives close by) Pretty sure that part is OK because he remotely helped hundreds of people on this message board do that in the past. We used Mikuni jets and stuff from a Barons kit to do that.
I thought I had a blown head gasket on the rear cylinder because the rear plugs get crudded up / black after every thousand miles (or less). Attached are the cylinder compression readings this morning after being cranked from cold start and then warmed up about 60 seconds before the test. Decompression solenoid was disconnected and the throttle opened up. I am at about zero ft elevation / sea level here in the Florida panhandle. Both were really equal and about 142 - 143 psi. .

The guy I bought it from had over six qts of oil in the crankcase that I drained out when I trailered it home. No telling how long he had ran it like that.
I removed the AIS and Barons block off plates were installed about a year ago.
My next thought is to do Curts SVS cure procedure step by step but I am wondering if the engine compression is ok to keep going forward?
Your thoughts?
Thanks
